Cisco Small Business 220 Series Smart Switches Vulnerabilities

Notes

Summary
Multiple vulnerabilities in the web-based management interface of Cisco Small Business 220 Series Smart Switches could allow an attacker to do the following: Hijack a user session Execute arbitrary commands as a root user on the underlying operating system Conduct a cross-site scripting (XSS) attack Conduct an HTML injection attack For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ciscosb-multivulns-Wwyb7s5E ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ciscosb-multivulns-Wwyb7s5E"]
Vulnerable Products
These vulnerabilities affect Cisco Small Business 220 Series Smart Switches if they are running firmware releases earlier than Release 1.2.0.6 and have the web-based management interface enabled. The web-based management interface is enabled through both HTTP and HTTPS by default. Determine Whether the Web-Based Management Interface Is Enabled To determine whether the web-based management interface is enabled through either HTTP or HTTPS, use the show running-config command on the device CLI. If both of the following lines are present in the configuration, the web-based management interface is disabled and the device is not affected: no ip http server no ip http secure server Any other output indicates that the web-based management interface is enabled on the device. In the web-based management interface, the HTTP Service and HTTPS Service are configured under Security > TCP/UDP Service.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by these vulnerabilities.
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities. Details about the vulnerabilities are as follows: CVE-2021-1542: Cisco Small Business 220 Series Smart Switches Weak Session Management Vulnerability A vulnerability in session management for the web-based management interface of Cisco Small Business 220 Series Smart Switches could allow an unauthenticated, remote attacker to bypass authentication protections and gain unauthorized access to the interface. The attacker could obtain the privileges of the highjacked session account, which could include administrative privileges on the device. This vulnerability is due to the use of weak session management for session identifier values. An attacker could exploit this vulnerability by using reconnaissance methods to determine how to craft a valid session identifier. A successful exploit could allow the attacker take actions within the management interface with privileges up to the level of the administrative user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvx57925 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx57925"] CVE ID:CVE-2021-1542 Security Impact Rating (SIR): High CVSS Base Score: 7.5 CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H CVE-2021-1541: Cisco Small Business 220 Series Smart Switches Remote Command Execution Vulnerability A vulnerability in the web-based management interface of Cisco Small Business 220 Series Smart Switches could allow an authenticated, remote attacker to execute arbitrary commands as a root user on the underlying operating system. The attacker must have valid administrative credentials on the device. This vulnerability is due to a lack of parameter validation for TFTP configuration parameters. An attacker could exploit this vulnerability by entering crafted input for specific TFTP configuration parameters. A successful exploit could allow the attacker to execute arbitrary commands as a root user on the underlying operating system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvx57935 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx57935"] CVE ID:CVE-2021-1541 Security Impact Rating (SIR): High CVSS Base Score: 7.2 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H CVE-2021-1543: Cisco Small Business 220 Series Smart Switches Cross-Site Scripting (XSS) Vulnerability A vulnerability in the web-based management interface of Cisco Small Business 220 Series Smart Switches could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected device. An attacker could exploit this vulnerability by persuading a user to click a malicious link and access a specific page. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information and redirect the user to an arbitrary page. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvx57830 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx57830"] CVE ID:CVE-2021-1543 Security Impact Rating (SIR): Medium CVSS Base Score: 6.1 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N CVE-2021-1571: Cisco Small Business 220 Series Smart Switches HTML Injection Vulnerability A vulnerability in web-based management of Cisco Small Business 220 Series Smart Switches could allow an unauthenticated, remote attacker to conduct a HTML injection attack. This vulnerability is due to improper checks of parameter values in affected pages. An attacker could exploit this vulnerability by persuading a user to follow a crafted link that is designed to pass HTML code into an affected parameter. A successful exploit could allow the attacker to alter the contents of a web page to redirect the user to potentially malicious websites. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvx57830 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx57830"] CVE ID:CVE-2021-1571 Security Impact Rating (SIR): Medium CVSS Base Score: 6.1 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has released free software updates that address the vulnerabilities described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/end-user-license-agreement.html ["https://www.cisco.com/c/en/us/products/end-user-license-agreement.html"] Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.
