DESCRIPTION:
rgod has reported a vulnerability and a weakness in Sysinfoscript,
which can be exploited by malicious people to disclose system
information or compromise a vulnerable system.
1) Input passed to the "name" parameter in sysinfo.cgi is not
properly sanitised before being used. This can be exploited to inject
and execute arbitrary shell commands via the ";" (semicolon)
character.
Example:
http://[host]/cgi-bin/sysinfo.cgi?action=systemdoc&name=;[code]
2) It is possible to disclose the full path to the installation by
setting the "action" parameter to "debugging".
The vulnerability and weakness have been reported in version 1.21.
Other versions may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised and
that path information is not returned to users.
