TITLE:
Website META Language Insecure Temporary Files

SECUNIA ADVISORY ID:
SA28856

VERIFY ADVISORY:
https://secunia.com/advisories/28856/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Website META Language 2.x
https://secunia.com/product/17492/

DESCRIPTION:
Two security issues have been reported in Website META Language,
which can be exploited by malicious, local users to perform certain
actions with escalated privileges.

The security issues are caused due to the wml_backend/p1_ipp/ipp.src
and wml_contrib/wmg.cgi scripts using temporary files in an insecure
manner. This can be exploited via symlink attacks to overwrite or
delete arbitrary files with the privileges of the user running the
program.

The security issues are reported in version 2.0.11. Other versions
may also be affected.

SOLUTION:
Restrict access to the temporary directory to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported via a Debian bug report.
