Cisco cleared a vulnerability in the web management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) that could allow an authenticated, remote attacker to perform an unauthorized system reset on an affected device.

This was one of eight vulnerabilities that ended up ranked in the high category, while there were six in the medium category and two as informational.

The WSA vulnerability is due to improper authorization controls for a specific URL in the web management interface.

An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could have a twofold impact: The attacker could either change the administrator password, gaining privileged access, or reset the network configuration details, causing a denial of service (DoS) condition.

In either scenario, manual intervention is required to restore normal operations, Cisco said in its advisory.

Cisco released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
