Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OpenEMR suffers from **OS Command Injection**. π **Consequences**: Attackers can execute arbitrary system commands via the `backup.php` file, potentially leading to full system compromise and data theft.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-78 (OS Command Injection)**. The flaw lies in `/interface/main/backup.php`. It fails to properly sanitize user input before passing it to system commands.β¦
π₯ **Affected**: **OpenEMR** (Open Source Medical System). Specifically versions prior to the patch mentioned in community releases (e.g., 5.0.2-1). π¦ **Component**: The `backup.php` interface module.
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Execute **System Commands** with the privileges of the web server.β¦
π **Public Exp?**: Yes. References from **SonarSource** and OpenEMR community confirm active discussion and proof-of-concept availability. Wild exploitation is possible if the endpoint is exposed.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for OpenEMR instances. Check if `/interface/main/backup.php` exists. π§ͺ **Test**: Send a crafted POST request attempting command injection (e.g., `; ls`).β¦
β **Fixed?**: **Yes**. OpenEMR released patches (e.g., **5.0.2 Patch 5**). π **Action**: Update to the latest patched version immediately via the official wiki or community release notes.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Mitigation**: Restrict access to `/interface/main/backup.php` via WAF or firewall rules.β¦
π₯ **Urgency**: **HIGH**. Medical data is critical. π‘ **Priority**: Patch immediately. This vulnerability puts **health records** at direct risk. Do not delay remediation.
