Title: MailEnable Mail Server HTTPMail Remote Heap Overflow Vulnerability
Severity: CRITICAL
Description:
MailEnable is a commercially available POP3 and SMTP server for the Windows platform.
The 'Professional' and 'Enterprise' editions of MailEnable are reported to be prone to a remote heap buffer overflow, allowing remote code execution.
It has been reported that HTTPMail, a mail access protocol based on WEBDAV, cannot properly handle very large GET requests. If the service has logging enabled and receives a request larger than 4045 bytes, or 8500 bytes with logging disabled, the attacker will overflow a buffer.
The overflow allows the attacker to control the EAX and ECX registers, allowing arbitrary code execution as SYSTEM.
All versions up to and including 1.18 are reported to be affected.
