What is CVE-2012-10046?

The E-Mail Security Virtual Appliance (ESVA) is susceptible to an unauthenticated command injection vulnerability in the learn-msg.cgi script. This issue arises from the failure to properly sanitize user-supplied input through the 'id' parameter, which permits attackers to inject arbitrary shell commands. Successful exploitation does not require authentication and enables full command execution on the underlying system, posing significant security risks.

Affected Version(s)

E-Mail Security Virtual Appliance ESVA_2057

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
