This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Groupwise. Authentication is not required to exploit this vulnerability.
The specific flaw exists in a function responsible for assembling an HTTP response. The following modules implement this functionality: gwpoa.exe, gwmta.exe, gwia.exe. When responding to an HTTP request sent to TCP port 7101 or 7100 or in the case of gwia.exe the user configured "Message Transfer Port", the process uses the client-specified "Host: " header to create an HTTP 301 redirection message. Within this code a local stack buffer is used to store the redirect location and can be overflown with a sufficiently long header value. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.
The HTTP interfaces for the GroupWise agents (Message Transfer Agent, Post Office Agent, Internet Agent, WebAccess Agent, Monitor Agent) are vulnerable to an exploit that could allow a remote attacker to execute arbitrary code on vulnerable installations of Novell Groupwise. Authentication is not required to exploit this vulnerability.
