Title
Cisco UCS and UCS-Based Appliances UEFI Shell Secure Boot Bypass Vulnerability
Summary
A vulnerability in the Unified Extensible Firmware Interface (UEFI) Shell implementation of Cisco UCS Servers and UCS-based appliances could allow an authenticated attacker with valid credentials for a user account with the role of user or admin or an unauthenticated attacker with physical access to an affected device to bypass UEFI Secure Boot validation checks and execute unauthorized software.
This vulnerability is due to the availability of memory write commands in the UEFI Shell while UEFI Secure Boot is enabled on a device. An attacker could exploit this vulnerability by selecting the UEFI Shell boot option at boot time and using available shell commands to modify UEFI memory variables. A successful exploit could allow the attacker to manipulate the preboot environment, overwrite UEFI Secure Boot-related memory values, and execute unauthorized software on the affected device.

Title
Cisco Secure Email S/MIME Ciphertext Decryption Vulnerabilty
Summary
Multiple vulnerabilities in the Secure/Multipurpose Internet Mail Extensions (S/MIME) decryption functionality of Cisco Secure Email could allow an unauthenticated, remote attacker to recover plain text from encrypted email messages.
These vulnerabilities are due to insufficient validation of message integrity. An attacker could exploit these vulnerabilities by using a machine-in-the-middle technique to intercept and modify traffic between email gateways. A successful exploit could allow the attacker to obtain plaintext content from the encrypted communication.

Title
Cisco Secure Email S/MIME Ciphertext Decryption Vulnerabilty
Summary
Multiple vulnerabilities in the Secure/Multipurpose Internet Mail Extensions (S/MIME) decryption functionality of Cisco Secure Email could allow an unauthenticated, remote attacker to recover plain text from encrypted email messages.
These vulnerabilities are due to insufficient validation of message integrity. An attacker could exploit these vulnerabilities by using a machine-in-the-middle technique to intercept and modify traffic between email gateways. A successful exploit could allow the attacker to obtain plaintext content from the encrypted communication.

Title
Cisco Desk Phone 9800 Series, IP Phone 7800 and 8800 Series, and Video Phone 8875 with SIP Software Denial of Service Vulnerability
Summary
A vulnerability in Cisco Desk Phone 9800 Series, Cisco IP Phone 7800 and 8800 Series, and Cisco Video Phone 8875 that are running Cisco Session Initiation Protocol (SIP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper memory management when an affected device processes HTTP packets. An attacker could exploit this vulnerability by sending a continuous stream of crafted HTTP packets to the device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, resulting in a DoS condition. A manual reboot of the device is required to recover from this condition.
Note: For this vulnerability to be exploitable, the phone must be registered to Cisco Unified Communications Manager (Unified CM) and have Web Access enabled. Web Access is disabled by default.

Title
Cisco Nexus 3000 and 9000 Series Switches Silicon One Hardware Abstraction Layer Remote Code Execution Vulnerability
Summary
A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute code with root privileges.
This vulnerability exists because TCP ports 43210 and 43211 are accessible in the default Layer 3 (L3) virtual routing and forwarding (VRF). A successful exploit could allow the attacker to connect to an affected device and send crafted input that could be executed as code with root privileges. The exploitation of this vulnerability could also cause the S1HAL process to crash, which could cause the device to reload.

Title
Cisco UCS and UCS-Based Appliances UEFI Shell Secure Boot Bypass Vulnerability
Summary
A vulnerability in the Unified Extensible Firmware Interface (UEFI) Shell implementation of Cisco UCS Servers and UCS-based appliances could allow an authenticated attacker with valid credentials for a user account with the role of user or admin or an unauthenticated attacker with physical access to an affected device to bypass UEFI Secure Boot validation checks and execute unauthorized software.
This vulnerability is due to the availability of memory write commands in the UEFI Shell while UEFI Secure Boot is enabled on a device. An attacker could exploit this vulnerability by selecting the UEFI Shell boot option at boot time and using available shell commands to modify UEFI memory variables. A successful exploit could allow the attacker to manipulate the preboot environment, overwrite UEFI Secure Boot-related memory values, and execute unauthorized software on the affected device.

Title
Cisco Secure Email S/MIME Ciphertext Decryption Vulnerabilty
Summary
Multiple vulnerabilities in the Secure/Multipurpose Internet Mail Extensions (S/MIME) decryption functionality of Cisco Secure Email could allow an unauthenticated, remote attacker to recover plain text from encrypted email messages.
These vulnerabilities are due to insufficient validation of message integrity. An attacker could exploit these vulnerabilities by using a machine-in-the-middle technique to intercept and modify traffic between email gateways. A successful exploit could allow the attacker to obtain plaintext content from the encrypted communication.

Title
Cisco Desk Phone 9800 Series, IP Phone 7800 and 8800 Series, and Video Phone 8875 with SIP Software Denial of Service Vulnerability
Summary
A vulnerability in Cisco Desk Phone 9800 Series, Cisco IP Phone 7800 and 8800 Series, and Cisco Video Phone 8875 that are running Cisco Session Initiation Protocol (SIP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper memory management when an affected device processes HTTP packets. An attacker could exploit this vulnerability by sending a continuous stream of crafted HTTP packets to the device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, resulting in a DoS condition. A manual reboot of the device is required to recover from this condition.
Note: For this vulnerability to be exploitable, the phone must be registered to Cisco Unified Communications Manager (Unified CM) and have Web Access enabled. Web Access is disabled by default.

Title
Cisco Nexus 3000 and 9000 Series Switches Silicon One Hardware Abstraction Layer Remote Code Execution Vulnerability
Summary
A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute code with root privileges.
This vulnerability exists because TCP ports 43210 and 43211 are accessible in the default Layer 3 (L3) virtual routing and forwarding (VRF). A successful exploit could allow the attacker to connect to an affected device and send crafted input that could be executed as code with root privileges. The exploitation of this vulnerability could also cause the S1HAL process to crash, which could cause the device to reload.

Title
Cisco Catalyst SD-WAN C8000V Authenticated Heap Buffer Overflow
Summary
SUMMARY: an authenticated heap buffer overflow in cisco catalyst
c8000v sd-wan allows an attacker with low privileges to corrupt
process memory and achieve remote code execution by sending a crafted
message of type 0x0d (13) with device mode 5.
this was tested on 17.06.03 as it is the only image i had access to.
https://bst.cisco.com/quickview/bug/CSCwu48719
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-notice-L4XfJg8S
===================== the vuln =====================
the core vuln is in vdaemon. vdaemon is the core control plane binary
used by catalyst to orchestrate stuff like secure tunneling and
joining new devices when they first are introduced to the sd-wan. thus
(again) its a juicy target to get initial access on.
the core vuln is at sub_2A4D0:
lea rdi, [r12+0F34h] ; peer struct
mov rbx, [rbp+src]
lea r15, [rbx+20h]
lea rsi, [rbx+24h]
mov edx, [rbx+20h]
call _memcpy
mov byte ptr [r14+rax+0F34h], 0 ; null term
the pseudocode, essenetially, is:
memcpy(&peer->f34h, msg->dat, msg->len);
peer->f34h[msg->len] = 0;
i assume you can see the major issue in here lol. we control the
length and src since we control the message. we get a heap buffer
overflow. in this case, we get two overflows:
; second overflow
lea rdi, [r12+0F86h]
lea rsi, [rbx+100h]
mov edx, [rbx+164h]
call _memcpy
mov byte ptr [r14+rax+0F86h], 0
this time to 0xf86 in peer.
peer is allocated in sub_21B20 once you xref it:
peer = (unsigned int *)((__int64 (__fastcall *)(__int64))g_mem)(0x1298);
so the peer struct is 4760 bytes large.
the peer struct looks like:
struct peer {
void *list_next;
void *list_prev;
uint8_t pad_10[16];
uint32_t peer_state;
uint32_t field_24;
uint8_t pad_28[14];
uint8_t flag_36;
uint8_t pad_37[101];
uint32_t msg_counter;
uint8_t pad_A0[232];
uint8_t addr_info[16];
uint8_t pad_198[161];
uint8_t tlv_block[128];
uint8_t pad_2B9[167];
uint8_t addr_data[56];
uint8_t field_398[24];
uint8_t pad_3B0[256];
void *conn_ptr;
struct timespec last_seen;
uint8_t pad_4C8[2668];
uint8_t vuln_buf_1[82]; // where we hit
uint8_t vuln_buf_2[106]; // where we hit again
uint8_t field_FF0[8];
char str_FF8[58];
uint8_t field_1032;
uint8_t pad_1033[12];
uint8_t field_103F;
uint8_t flag_1040;
uint8_t pad_1041[3];
uint32_t field_1044;
uint32_t field_1048;
uint8_t pad_104C[28];
void (*bev_ssl)(...); // funcptr HIT THIS HIT THIS
uint8_t pad_1070[48];
uint8_t field_10A0[128];
uint8_t field_1120[128];
char name1[41];
char name2[41];
uint8_t pad_11F2[14];
void *sub_obj;
uint8_t field_1208[144];
};
ideally, we could probably overflow the buffers to hit the function
ptr; put a stack pivot gadget then start ropping in the heap. later
versions of c8000v have pie + aslr obviously, so that would make
exploitation significantly harder but not impossible.
unforutnately the requirements to reach this heap bof mean that it
isnt preauth rce. youd still need a valid cert; but you could send a
message of type 13 (0x0D), or a REGISTER_TO_VMANAGE type, make the
device mode 5 (vManage device mode), then include your payload to hit
the sink.

"value": "SUMMARY: an authenticated heap buffer overflow in cisco catalyst\nc8000v sd-wan allows an attacker with low privileges to corrupt\nprocess memory and achieve remote code execution by sending a crafted\nmessage of type 0x0d (13) with device mode 5.\nthis was tested on 17.06.03 as it is the only image i had access to.\n\nhttps://bst.cisco.com/quickview/bug/CSCwu48719\n\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-notice-L4XfJg8S\n\n===================== the vuln =====================\n\nthe core vuln is in vdaemon. vdaemon is the core control plane binary\nused by catalyst to orchestrate stuff like secure tunneling and\njoining new devices when they first are introduced to the sd-wan. thus\n(again) its a juicy target to get initial access on.\n\nthe core vuln is at sub_2A4D0:\n\nlea rdi, [r12+0F34h] ; peer struct\nmov rbx, [rbp+src]\nlea r15, [rbx+20h]\nlea rsi, [rbx+24h]\nmov edx, [rbx+20h]\ncall _memcpy\nmov byte ptr [r14+rax+0F34h], 0 ; null term\n\n\nthe pseudocode, essenetially, is:\n\nmemcpy(\u0026peer-\u003ef34h, msg-\u003edat, msg-\u003elen);\npeer-\u003ef34h[msg-\u003elen] = 0;\n\ni assume you can see the major issue in here lol. we control the\nlength and src since we control the message. we get a heap buffer\noverflow. in this case, we get two overflows:\n\n; second overflow\nlea rdi, [r12+0F86h]\nlea rsi, [rbx+100h]\nmov edx, [rbx+164h]\ncall _memcpy\nmov byte ptr [r14+rax+0F86h], 0\n\nthis time to 0xf86 in peer.\n\npeer is allocated in sub_21B20 once you xref it:\n\n peer = (unsigned int *)((__int64 (__fastcall *)(__int64))g_mem)(0x1298);\n\nso the peer struct is 4760 bytes large.\n\nthe peer struct looks like:\n\nstruct peer {\n void *list_next;\n void *list_prev;\n uint8_t pad_10[16];\n uint32_t peer_state;\n uint32_t field_24;\n uint8_t pad_28[14];\n uint8_t flag_36;\n uint8_t pad_37[101];\n uint32_t msg_counter;\n uint8_t pad_A0[232];\n uint8_t addr_info[16];\n uint8_t pad_198[161];\n uint8_t tlv_block[128];\n uint8_t pad_2B9[167];\n uint8_t addr_data[56];\n uint8_t field_398[24];\n uint8_t pad_3B0[256];\n void *conn_ptr;\n struct timespec last_seen;\n uint8_t pad_4C8[2668];\n uint8_t vuln_buf_1[82]; // where we hit\n uint8_t vuln_buf_2[106]; // where we hit again\n uint8_t field_FF0[8];\n char str_FF8[58];\n uint8_t field_1032;\n uint8_t pad_1033[12];\n uint8_t field_103F;\n uint8_t flag_1040;\n uint8_t pad_1041[3];\n uint32_t field_1044;\n uint32_t field_1048;\n uint8_t pad_104C[28];\n void (*bev_ssl)(...); // funcptr HIT THIS HIT THIS\n uint8_t pad_1070[48];\n uint8_t field_10A0[128];\n uint8_t field_1120[128];\n char name1[41];\n char name2[41];\n uint8_t pad_11F2[14];\n void *sub_obj;\n uint8_t field_1208[144];\n};\n\nideally, we could probably overflow the buffers to hit the function\nptr; put a stack pivot gadget then start ropping in the heap. later\nversions of c8000v have pie + aslr obviously, so that would make\nexploitation significantly harder but not impossible.\n\nunforutnately the requirements to reach this heap bof mean that it\nisnt preauth rce. youd still need a valid cert; but you could send a\nmessage of type 13 (0x0D), or a REGISTER_TO_VMANAGE type, make the\ndevice mode 5 (vManage device mode), then include your payload to hit\nthe sink.\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives \u0026 RSS: https://seclists.org/fulldisclosure/"
