Unspecified vulnerability in TOS 2.1.x, 2.2.x before 2.2.5, and 2.5.x before 2.5.2 on TippingPoint IPS allows remote attackers to avoid detection by sending certain fragmented packets.

TippingPoint IPS before 20070710 does not properly handle a hex-encoded alternate Unicode '/' (slash) character, which might allow remote attackers to send certain network traffic and avoid detection, as demonstrated by a cmd.exe attack.
