Unauthenticated command execution via SMTP input overflow
Published Jul 15, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Cellopoint Secure Email Gateway before 4.5.0 allows remote attackers to execute system commands via SMTP input. The SMTP Listener accepts attacker-controlled input without adequate validation before stack-buffer processing; the affected field and copy operation are not publicly documented. No authentication or user interaction is required, and successful exploitation grants command execution on the gateway.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <4.5.0
- Affected versionversion=all <=4.5.0
