CVE-2019-16663

CWE-78Published: October 28, 2019· Updated: Jun 17, 2026

8.8

CVSS v3.1

Official Description

An issue was discovered in rConfig 3.9.2. An attacker can directly execute system commands by sending a GET request to search.crud.php because the catCommand parameter is passed to the exec function without filtering, which can lead to command execution.

Technical Analysis

CVE-2019-16663 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
