Optergy Proton - RCE (CVE-2019-7276)

CVE-2019-7276 is a critical vulnerability in Optergy Proton and Enterprise devices that allows remote attackers to achieve root code execution through a backdoor console. This flaw can be exploited without authentication, enabling attackers to fully compromise affected systems and potentially take complete control over device operations.

CrowdSec has been tracking this vulnerability and its exploits since 15th of October 2025.

Data from the CrowdSec community indicates that exploitation of CVE-2019-7276 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-2019-7276. 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 the backdoor console by sending requests to /tools/ajax/ConsoleResult.html, allowing unauthenticated remote code execution on Optergy Proton and Enterprise devices. Both GET and POST methods targeting this endpoint are used to execute arbitrary system commands.
