TITLE:
Cacti "cmd.php" Command Execution and SQL Injection

SECUNIA ADVISORY ID:
SA23528

VERIFY ADVISORY:
http://secunia.com/advisories/23528/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
Cacti 0.x
http://secunia.com/product/3793/

DESCRIPTION:
rgod has discovered three vulnerabilities in Cacti, which can be
exploited by malicious people to bypass certain security
restrictions, manipulate data and compromise vulnerable systems.

1) The cmd.php script does not properly restrict access to command
line usage and is installed in a web-accessible location.

Successful exploitation requires that "register_argc_argv" is
enabled.

2) Input passed in the URL to cmd.php is not properly sanitised
before being used in SQL queries. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "register_argc_argv" is
enabled.

3) The results from the SQL queries in 2) in cmd.php are not properly
sanitised before being used as shell commands. This can be exploited
to inject arbitrary shell commands.

The vulnerabilities are confirmed in version 0.8.6i. Other versions
may also be affected.

SOLUTION:
Move the "cmd.php" script to a not web-accessible path, and update
other scripts accordingly.

Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
rgod
