Vulnerability DetailsThis 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.
