Vulnerability Assessment Details
Tries to write a file using PatchLink Update Server
Detailed Explanation for this Vulnerability Assessment
The remote web server contains an ASP script that is affected by a
directory traversal flaw.
The remote host is running PatchLink Update Server, a patch and
vulnerability management solution.
The version of PatchLink Update Server installed on the remote fails
to sanitize input to the '/dagent/nwupload.asp' script of directory
traversal sequences and does not require authentication before
removing directories and writing to files as the user 'PLUS
ANONYMOUS'. An unauthenticated attacker can leverage this flaw to
remove directories required by the application and write arbitrary
content to files on the affected host.
Note that Novell ZENworks Patch Management is based on PatchLink
Update Server and is affected as well.
