Vulnerability Information

Severity: Critical
Vulnerability Published: 2011-02-16
Patch Published: 2011-02-16
CVE [?]: CVE-2011-0364
CPE [?]: cpe:/a:cisco:security_agent

Synopsis

The remote host has an endpoint security application installed that is potentially affected by a remote code execution vulnerability.

Description

According to the version identified on the Management Center for Cisco Agents web interface, the remote host is potentially affected by a remote code execution vulnerability. This is due to the 'webagent.exe' script failing to properly process POST request parameters. A remote, unauthenticated attacker can exploit this issue by creating an arbitrary file with a crafted 'st_upload' request, which the attacker could use to execute arbitrary code on the remote host.

Solution

Upgrade to Cisco Security Agent 6.0.2.145 or later, or apply the workaround specified in the vendor advisory.
