Cisco Intrusion Prevention System and IOS with Unicode Encoding Issue

CVE-2007-2688

Summary

The Cisco Intrusion Prevention System (IPS) and Cisco IOS with Firewall/IPS Feature Set are susceptible to vulnerabilities stemming from improper handling of both full-width and half-width Unicode character encodings. This flaw permits remote attackers to potentially bypass detection mechanisms designed for HTTP traffic. As a result, malicious activities could go unnoticed, compromising the security integrity of affected systems. Organizations using these products must implement remediation strategies to mitigate the risk of such evasion techniques effectively.
