Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: Admidio 5.0.6 and earlier versions suffer from missing permission and CSRF token validation in document/file modules.…
🛡️ **Root Cause**: CWE-862 (Missing Authorization). The system fails to verify if the user has the right permissions or a valid CSRF token before executing delete operations on files/folders.
Q3Who is affected? (Versions/Components)
📦 **Affected**: Admidio (Open Source Member Management System). Specifically versions **5.0.6 and earlier**. Components: Document and File modules.
Q4What can hackers do? (Privileges/Data)
💀 **Attacker Capabilities**: Can delete **any file or folder** within the system. Impact: High Integrity (I:H) and High Availability (A:H) impact. No confidentiality loss (C:N) directly, but destruction is total.
Q5Is exploitation threshold high? (Auth/Config)
⚡ **Exploitation Threshold**: **LOW**. CVSS Vector: AV:N/AC:L/PR:N/UI:N/S:U. No authentication (PR:N), no user interaction (UI:N), and low complexity (AC:L). It's a remote, unauthenticated attack.
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔍 **Public Exploit**: Currently **NO** public PoC or wild exploitation detected (POCs array is empty). However, the low CVSS score suggests it is easily exploitable by anyone with basic knowledge.
Q7How to self-check? (Features/Scanning)
🔎 **Self-Check**: Scan for Admidio instances (version <= 5.0.6). Check if the Document/File modules are accessible. Look for endpoints handling file deletion that lack CSRF tokens or proper permission checks.
Q8Is it fixed officially? (Patch/Mitigation)
🛠️ **Official Fix**: **YES**. Update to a patched version. Reference: [GitHub Advisory GHSA-rmpj-3x5m-9m5f](https://github.com/Admidio/admidio/security/advisories/GHSA-rmpj-3x5m-9m5f).
Q9What if no patch? (Workaround)
🚧 **No Patch Workaround**: Restrict access to the Document/File modules via WAF or network ACLs. Disable the file upload/download features if not essential. Implement strict input validation on the server side.
Q10Is it urgent? (Priority Suggestion)
🔥 **Urgency**: **HIGH**. With CVSS 8.6 (High), no auth required, and destructive capability (deletion), this is a critical risk. Patch immediately to prevent data destruction.
