Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: ClipBucket V5 has a critical file upload flaw. π **Consequences**: Attackers can upload and execute **webshells** or malicious files directly on the server. π₯ This leads to total server compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **CWE**: CWE-434 (Unrestricted Upload of File with Dangerous Type). π **Flaw**: The application performs **incorrect checks** on uploaded files.β¦
π’ **Vendor**: MacWarrior. π¦ **Product**: ClipBucket V5. π **Affected Versions**: Versions **5.5.1** and earlier (up to build 238). β οΈ If you are running an older build, you are at risk.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full Remote Code Execution (RCE). π **Data**: Complete access to server files and databases. π **Impact**: High CVSS score (9.8).β¦
π₯ **Public Exploit**: YES. A PoC is available on GitHub (shreyas-malhotra/CVE-2025-21624). π’ **Status**: Active. Wild exploitation is likely imminent given the low barrier to entry and public proof-of-concept.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for ClipBucket V5 instances. π€ **Test**: Attempt to upload a malicious file (e.g., PHP shell) via the video upload interface.β¦
β **Fixed**: YES. A patch commit exists: `893bfb0f1236c4a59b5e2843ab8d27a1e491b12b`. π **Advisory**: See GHSA-98vm-2xqm-xrcc on GitHub. π **Action**: Update to the latest version immediately to apply the fix.
Q9What if no patch? (Workaround)
π« **Workaround**: If patching is impossible, **disable file uploads** entirely. π **Restrict**: Block upload endpoints via WAF rules.β¦
π΄ **Priority**: CRITICAL (P1). π **Urgency**: Immediate action required. With CVSS 9.8 and public PoC, this is an **active threat**. Deploy patches or mitigations TODAY to prevent server takeover.
