CVE-2005-2841
HighSummary
Buffer overflow vulnerability in the Firewall Authentication Proxy for FTP and/or Telnet Sessions in Cisco IOS versions 12.2ZH, 12.2ZL, 12.3, 12.3T, 12.4, and 12.4T. A remote attacker can exploit crafted user authentication credentials to cause a denial of service (DoS) and potentially execute arbitrary code.
Risk Assessment
The risk to the organization includes potential disruption of network services and possible takeover of the Cisco device, leading to breaches of data confidentiality and integrity.
Recommendation
It is recommended to immediately upgrade Cisco IOS to a version without this vulnerability and implement network traffic filters to restrict access to proxy authentication services.
