CVE-2004-2348 in Antigen
Summary
by MITRE
Sybari AntiGen for Domino 7.0 Build 722 SR2 alows remote attackers to cause a denial of service (hang) via an encrypted ZIP file with the "include full path info" option set, as used by certain variants of the Beagle/Bagle worm.

The vulnerability identified as CVE-2004-2348 affects Sybari AntiGen for Domino 7.0 Build 722 SR2, a security solution designed to protect IBM Domino email servers from various threats. This particular weakness stems from the software's improper handling of encrypted ZIP files that contain full path information, creating a specific condition that allows remote attackers to induce a denial of service state. The flaw is particularly concerning because it leverages techniques commonly employed by malware variants, specifically those associated with the Beagle/Bagle worm family that was prevalent during the early 2000s era.
The technical implementation of this vulnerability occurs when the AntiGen system processes encrypted ZIP archives with the "include full path info" option enabled. This configuration causes the system to attempt to extract and analyze the full directory paths contained within the compressed files, leading to a processing loop or resource exhaustion that results in system hang or complete service unavailability. The vulnerability represents a classic buffer over-read or infinite loop scenario where the software fails to properly validate or limit the processing of file path information within encrypted archives. This type of flaw aligns with CWE-129, which addresses improper validation of length of input buffers, and CWE-674, which covers uncontrolled resource consumption.
The operational impact of this vulnerability extends beyond simple service disruption, as it represents a sophisticated attack vector that could be exploited by threat actors to systematically target Domino email servers. The fact that this vulnerability can be triggered remotely without authentication makes it particularly dangerous in networked environments where email servers serve as critical communication infrastructure. Organizations relying on Sybari AntiGen for Domino would experience complete service interruption, potentially affecting business continuity and email communications for extended periods until the system is manually restarted or the vulnerable software is patched.
Mitigation strategies for this vulnerability should include immediate application of vendor patches or updates to the Sybari AntiGen software to address the specific handling of encrypted ZIP files. Network administrators should implement additional monitoring and alerting for unusual resource consumption patterns that might indicate exploitation attempts. The ATT&CK framework categorizes this type of vulnerability under T1499, which covers network denial of service attacks, and T1071, which addresses application layer protocol usage. Organizations should also consider implementing network segmentation and access controls to limit exposure, while maintaining proper backup and recovery procedures to minimize downtime during remediation efforts.
