CVE-2005-4558: Deerfield Visnetic Mail Server

Medium severity, CVSS 6.5. EPSS: 8.5% chance of exploitation in the next 30 days.

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 restrict acceptable values for the language parameter to mail/settings.html before it is stored in a database, which can allow remote authenticated users to include arbitrary PHP code via a URL in a modified lang_settings parameter to mail/index.html.

Affected products

• Deerfield Visnetic Mail Server: version 8.3.0_build1 only
• Icewarp Web Mail: version 5.5.1 only
