Rule Name: Cacti Server Remote Code Execution Vulnerability (CVE-2024-29895)
Severity:
CVE ID:
Rule Protection Details
Description: Cacti provides an operational monitoring and fault management framework. A command injection vulnerability on the 1.3.x DEV branch allows any unauthenticated user to execute arbitrary command on the server when `register_argc_argv` option of PHP is `On`. In `cmd_realtime.php` line 119, the `$poller_id` used as part of the command execution is sourced from `$_SERVER[argv]`, which can be controlled by URL when `register_argc_argv` option of PHP is `On`. And this option is `On` by default in many environments such as the main PHP Docker image for PHP. Commit 53e8014d1f082034e0646edc6286cde3800c683d contains a patch for the issue, but this commit was reverted in commit 99633903cad0de5ace636249de16f77e57a3c8fc.
Impact: An attacker can execute arbitrary code via a successful exploit in the context of the vulnerable software.
Affected OS: Windows, Linux, Others
