Detailsinfo

A vulnerability classified as very critical was found in ISS Proventia and RealSecure (affected version unknown). This vulnerability affects an unknown functionality of the component PAM Module. The manipulation as part of a ICQ Server Reply leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Multiple stack-based buffer overflows in the ICQ parsing routines of the ISS Protocol Analysis Module (PAM) component, as used in various RealSecure, Proventia, and BlackICE products, allow remote attackers to execute arbitrary code via a SRV_MULTI response containing a SRV_USER_ONLINE response packet and a SRV_META_USER response packet with long (1) nickname, (2) firstname, (3) lastname, or (4) email address fields, as exploited by the Witty worm.

The bug was discovered 03/08/2004. The weakness was presented 03/18/2004 by Briley Hassell-Jack (DiGiT) with eEye Digital Security (Website). The advisory is shared for download at xforce.iss.net. This vulnerability was named CVE-2004-0362 since 03/18/2004. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 07/13/2025).

It is possible to download the exploit at immunitysec.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 10 days. During that time the estimated underground price was around $25k-$100k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 34023 (ISS Protocol Analysis Module ICQ Parsing Stack Overflow Vulnerabilities).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at iss.net. A possible mitigation has been published immediately after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2446. In this case the pattern |05 00| is used for detection. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8497.

The vulnerability is also documented in the databases at X-Force (15543), Exploit-DB (168), SecurityFocus (BID 9913†), OSVDB (4355†) and Secunia (SA11073†).
