NSFOCUS Security Advisory (SA2007-02)
Cisco Security Agent Remote Buffer Overflow Vulnerability
Release Date: 2007-12-06
CVE ID: CVE-2007-5580
Affected systems & software
Cisco Security Agent for Windows < 188.8.131.522
Cisco Security Agent for Windows < 184.108.40.206
Cisco Security Agent for Windows < 220.127.116.11
Cisco Security Agent for Windows < 18.104.22.168
Unaffected systems & software
NSFOCUS Security Team discovered a remote buffer overflow vulnerability in
Cisco Security Agent for Windows which allows remote code execution by sending
a malicious SMB request.
Cisco Security Agent is a security software agent that provides threat protection
for server and desktop computing systems.
A driver bundled with Cisco Security Agent for Windows does not correctly
check the data length provided by users when processing a SMB packet, which
might trigger a stack buffer overflow in the system kernel. A remote attacker
might cause system with CSA installed to restart or BSOD. By sending carefully
crafted data an attacker might cause remote code execution, thus gains complete
control over the system.
By default CSA allows access to TCP ports 139 and 445. After establishing a
session to TCP ports 139 and 445, an attacker can complete an exploitation
without any authentication simply by sending a single packet.
Cisco Security Agent for Windows version 22.214.171.124 and prior are affected.
Other Cisco software that uses CSA component is also affected.
* Restrict access to TCP ports 139 and 445.
