Summary

The Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, allowing remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets sent to UDP port 2048.

Risk Assessment

The lack of authentication in WCCP poses a risk of redirecting network traffic, potentially leading to data confidentiality loss and man-in-the-middle attacks.

Recommendation

It is recommended to upgrade to a newer version of Cisco IOS that implements authentication mechanisms for WCCP to minimize the risk of attacks.
