CVE-2005-4559: n/a vulnerability

mail/include.html in IceWarp Web Mail 5.5.1, as used by Merak Mail Server 8.3.0r and VisNetic Mail Server version 8.3.0 build 1, does not properly initialize the default_layout and layout_settings variables when an unrecognized HTTP_USER_AGENT string is provided, which allows remote attackers to access arbitrary files via a request with an unrecognized User Agent that also specifies the desired default_layout and layout_settings parameters.

Security readout for executives and security teams

This older IceWarp Web Mail flaw can let a remote attacker access files on the mail server when the webmail component mishandles an unrecognized browser User-Agent. It matters mainly for organizations still running the specific legacy IceWarp, Merak, or VisNetic versions named in the sources. Exposure is most likely on internet-facing legacy webmail deployments using the named IceWarp Web Mail component. Modern or unrelated IceWarp versions are not confirmed affected by the supplied sources. Prioritize quickly if any named legacy webmail is internet-facing, because arbitrary file access on mail infrastructure can expose credentials or sensitive messages. If those products are absent, urgency is low. Mitigation focus: Inventory exposed IceWarp, Merak, and VisNetic webmail instances.; Confirm whether IceWarp Web Mail 5.5.1 or named mail server versions are present.; Check vendor or archived Secunia guidance for fixed versions or configuration workarounds..
