Vulnerability Details

This vulnerability allows remote attackers to delete all files on a system with a vulnerable installation of the Novell iPrint Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.

The specific flaw exists within the nipplib.dll module that can be reached via the ienipp.ocx ActiveX control with CLSID 36723f97-7aa0-11d4-8919-FF2D71D0D32C. The CleanUploadFiles method appears to be used to remove temporary files within a contained directory. However, due to a logic flaw a remote attacker can abuse the function to force the process to recursively delete all files on the target system.

Novell has issued an update to correct this vulnerability. More details can be found at:
