Synopsis

The remote CGI is vulnerable to multiple flaws.

Description

webadmin.dll was found on the web server. Old versions of this CGI suffered from numerous problems: - installation path disclosure - directory traversal, allowing anybody with administrative permission on WebAdmin to read any file - buffer overflow, allowing anybody to run arbitrary code on the server with SYSTEM privileges.

Note that no attack was performed, and the version number was not checked, so this might be a false alert

Solution

Upgrade to Alt-N WebAdmin 2.0.5 or later.
