Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: CyberPanel suffers from a **Command Injection** vulnerability. π **Consequences**: Attackers can bypass authentication and execute arbitrary commands on the server.β¦
π‘οΈ **Root Cause**: Improper validation of the `statusfile` parameter in `/ftp/getresetstatus` and `/dns/getresetstatus` endpoints. π **Flaw**: The parameter is directly used in a shell command.β¦
π₯ **Affected**: Users of **CyberPanel** (developed by Usman Nasir). π¦ **Components**: Specifically the `dns/views.py` module. π **Context**: Active exploitation noted in late 2024.β¦
π **Privileges**: Remote Code Execution (RCE) with **no authentication required** (PR:N). π **Data**: Full access to server files, databases, and DNS/email configurations. β οΈ **Impact**: High severity (CVSS 9.8).β¦
π₯ **Public Exp**: **YES**. Multiple PoCs and scanners are available on GitHub (e.g., `refr4g`, `i0x29A`, `qnole000`). π‘ **Scanners**: Nuclei templates exist for automated detection.β¦
π **Self-Check**: Use the provided Python scanners or Nuclei templates. π§ͺ **Test**: Send an **OPTIONS** request to `/ftp/getresetstatus` or `/dns/getresetstatus` with a malicious `statusfile` parameter.β¦
π οΈ **Official Fix**: Check CyberPanel's changelog for updates. π’ **Status**: As of Oct 2024, massive attacks are occurring. Users must verify if their version is patched.β¦
π¨ **Urgency**: **CRITICAL**. π΄ **Priority**: P1. With CVSS 9.8 and active wild exploitation (PSAux Ransomware), immediate action is required. Do not wait. Patch or mitigate NOW.
