A vulnerability has been identified in Novell GroupWise, which could be exploited by attackers to remotely take complete control of an affected system. This issue is caused by a stack overflow error in the WebAccess agent (GWINTER.exe) when processing an overly long (more than 335 bytes) HTTP Basic authentication request sent to port 7205/TCP or 7211/TCP, which could be exploited by remote unauthenticated attackers to execute arbitrary commands with elevated privileges by sending specially crafted base64 data to a vulnerable application.
