A vulnerability was found in ISS BlackICE PC Protection and classified as critical. Affected by this issue is the component Cross Site Scripting Detection. The manipulation as part of POST/PUT/DELETE/OPTIONS Request leads to privilege escalation. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

The weakness was shared 06/14/2003 by Marc Ruef with scip AG (Website). The advisory is shared for download at computec.ch. This vulnerability is handled as CVE-2003-5001. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1068. The problem is said to lie in the detection of cross-site scripting vulnerabilities when embedded within various HTTP requests. Specifically, BlackICE does not match cross-site scripting attacks embedded within PUT and DELETE requests. As a result an attacker may be capable of evading intrusion detection while carrying out these attacks against a target system.

A public exploit has been developed by Marc Ruef in HTTP Request and been published immediately after the advisory. The exploit is available at computec.ch. It is declared as proof-of-concept. As 0-day the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 11492 (Sambar Server Multiple Script XSS), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses : XSS, running in the context r and relying on port 80.

Upgrading eliminates this vulnerability. The upgrade is hosted for download at iss.com. Attack attempts may be identified with Snort ID 1497.

The vulnerability is also documented in the databases at Tenable (11492) and SecurityFocus (BID 7942†). cgisecurity.com is providing further details.
