SiteGuard Server Edition command injection grants root or SYSTEM access, now exploited
SiteGuard Server Edition has an OS command injection flaw that lets a low-privileged local user run commands as root or SYSTEM. CISA confirms active exploitation. Apply the vendor's mitigations now, since no fixed version is listed.
In plain terms
SiteGuard Server Edition, from EG Secure Solutions (listed by NVD under the vendor name e-guardian), has a flaw called OS command injection. The software passes attacker-influenced input to the operating system as part of a command, so an attacker can slip in commands of their own. Those commands run with the highest privileges on the machine: root on Linux or Unix systems, SYSTEM on Windows.
The attacker needs some form of access to the system running SiteGuard first, but only a low-privileged account. Any organisation running SiteGuard Server Edition should treat this as urgent. The US cybersecurity agency CISA has confirmed that attackers are already exploiting it.
