NVD-CWE-OtherPublished: August 17, 2004· Updated: Jun 16, 2026
Official Description
The (1) address.html and possibly (2) calendar.html pages in Merak Mail Server 5.2.7 allow remote attackers to gain sensitive information via an invalid HTTP request, which reveals the installation path. NOTE: it is unclear whether the calendar.html is an exposure, since the path is leaked in web logs that may only be available to the administrators, who would have access to the path through legitimate means.
Technical Analysis
CVE-2004-1720 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2004-1720. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
