Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version and configuration, the Cisco Adaptive Security Appliance (ASA) software running on the remote device is affected by an XML command injection vulnerability in the web-based management interface due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via specially crafted XML input, to inject arbitrary XML commands, resulting in an impact to the integrity of the device.

Note that Cisco considers this vulnerability to be low/medium severity, and as a result the existing check information may not be complete from the vendor. For additional verification, please contact TAC Cisco support.
