Where:
From remote
Impact:
System access,
Solution Status:

CVE Reference(s):
Description
eliteb0y has discovered a vulnerability in Mercury Mail Transport System, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within Mercury/32 SMTP Server Module (mercurys.dll) when processing arguments to the AUTH CRAM-MD5 command. This can be exploited to cause a stack-based buffer overflow via an overly long, specially-crafted argument passed to the affected command.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 4.51. Other versions may also be affected.
Solution:
Update to version 4.52.
