What is CVE-2019-10669?

A command injection vulnerability exists in the LibreNMS software through version 1.47, specifically in the file html/includes/graphs/device/collectd.inc.php. User-supplied parameters are inadequately sanitized using the mysqli_escape_real_string function, which fails to appropriately escape critical command line syntax characters. This failure enables attackers to inject arbitrary commands into the variable $rrd_cmd, which is executed through the passthru() function. Consequently, this vulnerability poses a risk of unauthorized command execution, potentially compromising the integrity of the system.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
