Name of the Vulnerable Software and Affected Versions Cisco Small Business RV320 versions not specified Cisco Small Business RV325 versions not specified Cisco Small Business RV016 versions not specified Cisco Small Business RV042 versions not specified Cisco Small Business RV082 versions not specified

Description The issue is related to the lack of input validation in the web-based management interface of the affected devices. This could allow a remote attacker with administrative privileges to execute arbitrary commands on the device by sending specially crafted requests. The vulnerabilities exist because the web-based management interface does not properly validate user-supplied input to scripts. An attacker could exploit this by sending malicious requests to an affected device, potentially allowing the execution of arbitrary commands with root privileges on the underlying operating system.

Recommendations For Cisco Small Business RV320, update to a version that fixes the input validation issue in the web-based management interface. For Cisco Small Business RV325, update to a version that fixes the input validation issue in the web-based management interface. For Cisco Small Business RV016, update to a version that fixes the input validation issue in the web-based management interface. For Cisco Small Business RV042, update to a version that fixes the input validation issue in the web-based management interface. For Cisco Small Business RV082, update to a version that fixes the input validation issue in the web-based management interface. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation.
