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.
