Title: Mirabilis ICQ Web Front Plug-In DoS Vulnerability

Severity: MODERATE

Description:

ICQ is a internet instant messaging application by Mirabilis. The ICQ Web Front plug-in assists a user in designing, creating and hosting a personal web site. Once the user is online, Web Front plug-in will serve requested web pages residing on the user's local machine to remote users.

Due to the handling of unusual input in a GET request, ICQ Web Front plug-in is subject to a denial of service.

Submitting a GET request composed of approx 86 metacharacters (ie. %, .., \, and various ascii encoded characters) will cause the server to consume all available system memory. This consumption of available resources will eventually cause the service to crash and possibly other applications depending on it.

A restart of the service is required in order to gain normal functionality.

Affected Products:

  • Mirabilis ICQ 2000.0.0 b Build 3278
