Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: CyberPanel suffers from a **Command Injection** vulnerability. ๐ **Consequences**: Attackers can bypass authentication and execute arbitrary commands on the server.โฆ
๐ก๏ธ **Root Cause**: Improper validation of the `statusfile` parameter in `/ftp/getresetstatus` and `/dns/getresetstatus` endpoints. ๐ **Flaw**: The parameter is directly used in a shell command.โฆ
๐ฅ **Affected**: Users of **CyberPanel** (developed by Usman Nasir). ๐ฆ **Components**: Specifically the `dns/views.py` module. ๐ **Context**: Active exploitation noted in late 2024.โฆ
๐ **Privileges**: Remote Code Execution (RCE) with **no authentication required** (PR:N). ๐ **Data**: Full access to server files, databases, and DNS/email configurations. โ ๏ธ **Impact**: High severity (CVSS 9.8).โฆ
๐ฅ **Public Exp**: **YES**. Multiple PoCs and scanners are available on GitHub (e.g., `refr4g`, `i0x29A`, `qnole000`). ๐ก **Scanners**: Nuclei templates exist for automated detection.โฆ
๐ **Self-Check**: Use the provided Python scanners or Nuclei templates. ๐งช **Test**: Send an **OPTIONS** request to `/ftp/getresetstatus` or `/dns/getresetstatus` with a malicious `statusfile` parameter.โฆ
๐ ๏ธ **Official Fix**: Check CyberPanel's changelog for updates. ๐ข **Status**: As of Oct 2024, massive attacks are occurring. Users must verify if their version is patched.โฆ
๐จ **Urgency**: **CRITICAL**. ๐ด **Priority**: P1. With CVSS 9.8 and active wild exploitation (PSAux Ransomware), immediate action is required. Do not wait. Patch or mitigate NOW.
