CVE-2004-0052: Multiple content security gateway and antivirus products allow remote attackers to bypass content restricti...

Security readout for executives and security teams

This CVE describes an email filtering weakness: some security gateways or antivirus filters may interpret malformed MIME separators differently than the recipient’s mail client. That mismatch can let restricted content pass filtering. The provided sources do not name specific affected products, patches, CVSS score, or current exploitation. Organizations relying on older or affected mail content security gateways, antivirus scanners, or MIME-filtering systems may be exposed. The bundle lists affected vendor and product as n/a, so exposure must be determined from local product inventories and vendor advisories. Prioritize assessment where email filtering is a primary control against malware, data leakage, or prohibited attachments. Urgency depends on whether deployed products match vendor-identified affected versions, which the provided sources do not enumerate. Mitigation focus: Identify mail gateways, antivirus scanners, and content filters that parse MIME email.; Check each vendor’s advisory or support channel for CVE-2004-0052 guidance.; Apply available vendor updates or supported configuration changes..
