Cisco Small Business RV042, RV042G, RV320, and RV325 Remote Command Execution Vulnerabilities
Description
A vulnerability in the web-based management interface of Cisco Small Business RV042, RV042G, RV320, and RV325 Routers could allow an authenticated, Administrator-level, remote attacker to execute arbitrary code as the root user. To exploit this vulnerability, an attacker would need to have valid Administrator credentials on the affected device.
This vulnerability is due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system as the root user.

Authenticated admin-level remote code execution in Cisco Small Business RV042, RV042G, RV320, and RV325 routers due to improper input validation.
Vulnerability
A vulnerability in the web-based management interface of Cisco Small Business RV042, RV042G, RV320, and RV325 Routers (all software releases) allows an authenticated Administrator-level remote attacker to execute arbitrary code as the root user. The issue stems from improper validation of user-supplied input in the web-based management interface [1].
Exploitation
An attacker must have valid Administrator credentials on the affected device. The attacker then sends crafted HTTP requests to the web-based management interface, triggering the improper input validation and leading to code execution [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code on the underlying operating system as the root user, resulting in full compromise of the device [1].
Mitigation
Cisco has not released and will not release software updates because the affected products are past their End of Software Maintenance Releases. No workarounds are available. Users should consider migrating to supported products [1].
