Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Critical Remote Code Execution (RCE) in CyberPanel. π **Consequences**: Attackers gain full control over the server, leading to data theft, ransomware deployment, or system destruction.β¦
π― **Affected**: CyberPanel versions **v2.3.6** and **v2.3.7** (unpatched). π¦ **Component**: The `upgrademysqlstatus` API endpoint. If you are running these versions, you are in the danger zone!
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Remote attackers can execute **arbitrary commands** with the privileges of the web server process.β¦
β‘ **Threshold**: Extremely Low. π **Auth**: No authentication required (Pre-Auth). π **Network**: Accessible over the network (AV:N). You donβt even need a password to trigger this exploit!
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Exploit Status**: YES, Public PoCs exist on GitHub. π **Wild Exploitation**: Actively exploited in the wild by the **PSAUX** ransomware group targeting ~22,000 instances. Do not wait!
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the endpoint `/dataBases/upgrademysqlstatus`. Use Nuclei templates or the provided Python PoCs to test if the CSRF token bypass works.β¦
π οΈ **Fix**: Upgrade to a version **after** commit `5b08cd6`. The vendor has acknowledged the issue. Check the official CyberPanel changelogs for the patched release. Immediate update is non-negotiable.
Q9What if no patch? (Workaround)
π§ **Workaround**: If you can't patch immediately, **block external access** to the `/dataBases/` directory via WAF or firewall rules. Disable the endpoint if possible. This is a temporary band-aid, not a cure!
Q10Is it urgent? (Priority Suggestion)
π¨ **Urgency**: CRITICAL (Priority 1). β³ **Time**: Act NOW. With active ransomware campaigns exploiting this, every minute counts. Patch immediately or isolate the server to prevent catastrophic data loss.
