Title: MyWebServer GET Request Buffer Overflow Vulnerability

Severity: CRITICAL

Description:

MyWebServer is an application and web server for Microsoft Windows operating systems.

MyWebServer is prone to a remotely exploitable buffer overflow condition. This is due to insufficient bounds checking of headers in incoming GET requests. GET requests of 1000+ bytes may trigger the condition.

Successful exploitation of this condition may allow remote attackers to execute arbitrary instructions with the privileges of the webserver. Exploitation may lead to a full compromise of the underlying host as the webserver will typically run in the SYSTEM context.

Affected Products:

  • MyWebServer MyWebServer 1.0.1
  • MyWebServer MyWebServer 1.0.2
