Sybari · Sybari Antigen · CVE-2005-3027
**Name of the Vulnerable Software and Affected Versions**
Sybari Antigen version 8.0 SR2
**Description**
The issue allows remote attackers to bypass custom filter rules and send file attachments of arbitrary file types via a message with a subject of "Antigen forwarded attachment". This occurs because Sybari Antigen 8.0 SR2 does not properly filter SMTP messages.
**Recommendations**
For Sybari Antigen version 8.0 SR2, consider implementing additional filtering rules to restrict file attachments based on type to mitigate the risk of exploitation. As a temporary workaround, restrict the ability to send messages with subjects that could bypass existing filter rules.
