Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A Directory Traversal flaw in Severalnines Cluster Control. ๐ **Consequences**: Remote attackers can read sensitive system files via the CMON API. Itโs a critical data leak risk!
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Directory Traversal vulnerability. ๐ **Flaw**: The CMON API fails to sanitize input, allowing attackers to include and display arbitrary file contents in HTTP requests.
Q3Who is affected? (Versions/Components)
๐ฏ **Affected Versions**:
โข 1.9.8 (before 1.9.8-9778)
โข 2.0.0 (before 2.0.0-9779)
โข 2.1.0 (before 2.1.0-9780).
โ ๏ธ Check your Cluster Control version immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Power**: Since Cluster Control often runs as **root**, hackers can retrieve:
โข `/etc/shadow` & `/etc/passwd` ๐ค
โข `/root/.ssh/id_rsa` ๐
โข `/etc/cmon.cnf` (RPC Key) ๐
Full system compromise potential!
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: Low! ๐ **Auth**: Remote exploitation via CMON API (Ports 9500/9501). โ๏ธ **Config**: No complex setup needed. If the port is open, youโre vulnerable.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฅ **Public Exp?**: YES! ๐ **PoC**: Available on GitHub by Redshift Cyber Security. ๐ **Wild Exploitation**: High risk. Nuclei templates also exist for automated scanning.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for open ports **9500** and **9501**. ๐งช **Test**: Use the provided PoC script to attempt reading `/etc/passwd`. ๐ **Tool**: Run Nuclei with the CVE-2024-41628 template.
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Fix**: YES! ๐ **Patch**: Updated versions released on July 24th, 2024. ๐ **Action**: Upgrade to 1.9.8-9778+, 2.0.0-9779+, or 2.1.0-9780+ immediately.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Block ports **9500/9501** at the firewall level. ๐ซ **Restrict**: Ensure CMON API is not exposed to the public internet. ๐ Limit access to trusted IPs only.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: CRITICAL! ๐จ **Priority**: Patch NOW. ๐ **Risk**: High severity due to root privileges and easy exploitation. Donโt wait!
