NetAlertX - Authentication Bypass (CVE-2024-46506)

CVE-2024-46506 is a critical unauthenticated command injection vulnerability in NetAlertX versions 23.01.14 through 24.x before 24.10.12, stemming from a lack of authentication in the savesettings function. Exploited in the wild, this flaw allows remote attackers to execute arbitrary commands on the affected system via settings.php and util.php, potentially leading to full system compromise, data theft, or service disruption.

CrowdSec has been tracking this vulnerability and its exploits since 24th of September 2025.

Data from the CrowdSec community indicates that exploitation of CVE-2024-46506 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations. Data from the CrowdSec community also indicates a gradual decrease in attacks targeting CVE-2024-46506. While still present in the wild, exploitation levels have dropped noticeably week-over-week. This may signal that the vulnerability is becoming less relevant or that defenses are improving fast enough for attackers to lose interest.

Attackers exploit unauthenticated POST requests to /php/server/util.php with function=savesettings to inject arbitrary commands, followed by execution via function=addToExecutionQueue. Subsequent GET requests to /api/table_settings.json may be used to verify successful code execution.
