Vulnerability Of Multitude Of CISCO Small Business Routers To XSS Attacks

Cisco has notified its customers of a severe vulnerability. As a consequence, it affects many Small Business RV Series Router models.

This risk, CVE-2024-20362, poses a major risk. Additionally, it allows unauthenticated, remote attackers to use cross-site scripting (XSS).

The RV016, RV042, RV042G, RV082, RV320, and RV325 routers are among those impacted. They are often used in small business contexts for secure internet connectivity and VPN access.

A Glance At CVE-2024-20362

The affected routers have a vulnerability. This vulnerability arises from insufficient input validation in their web-based management interfaces.

Attackers can exploit this flaw by convincing users to click on a specially crafted link. This can lead to executing arbitrary script code in the context of the affected interface. Additionally, it can also be susceptible to the potential leakage of sensitive and browser-based information.

The Common Vulnerabilities and Exposures (CVE) system has assigned this vulnerability the identifier CVE-2024-20362. Furthermore, it relates this flaw with a base score of 6.1 on the Common Vulnerability Scoring System (CVSS).

This score reflects a moderate severity level. Later on, it emphasized the need for affected users. Along with this, the score inspired them to take immediate action to mitigate the risk.

Affected Products And Mitigation Strategies

The alert states that all software versions for the RV016, RV042, RV042G, RV082, RV320, and RV325 routers are insecure.

This vulnerability does not impact other models in the Cisco RV Series, including the RV160, RV260, and RV340 series routers.

In the shortage of software upgrades to resolve CVE-2024-20362, Cisco has provided particular mitigation measures for vulnerable users.

Disabling remote management is advised for the RV320 and RV325 models.

For the RV016, RV042, RV042G, and RV082 models, Cisco recommends deactivating remote management. Plus it also appreciated and restricted access to ports 443 and 60443, which may be done using the router's web-based administration interface.

Fixed Software

Cisco has indicated that it would not distribute software upgrades to fix this vulnerability. But it is possible until the impacted routers have reached the end-of-life stage.

Customers are recommended to review these products' end-of-sale and end-of-life notifications. Furthermore, they also consider upgrading to newer models. Over time, these models will continue to receive security enhancements and maintenance.

This event highlights the significance of conducting frequent security assessments. Besides, promptly implement mitigations or updates to guard against emerging cybersecurity threats.

Customers should check Cisco's security advisories on a regular basis. Along with this, they should also contact the Cisco Technical Assistance Center (TAC) or their authorized service suppliers. The main purpose of doing so was to guarantee the security and resilience of their network infrastructure.
