Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Path Traversal vulnerability in Firebird's external engine plugin loader.β¦
π‘οΈ **Root Cause**: **CWE-22 (Path Traversal)**. The flaw lies in failing to filter path separators or `..` components when concatenating user-supplied engine names into file system paths. π
π» **Attacker Capabilities**: With authentication, hackers can execute arbitrary code. π― This results in **High** impact on Confidentiality, Integrity, and Availability (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Medium**. Requires **Local Network** access (AV:N) and **Low Complexity** (AC:L). However, it strictly requires **User Authentication** (PR:L). π
Q6Is there a public Exp? (PoC/Wild Exploitation)
π΅οΈ **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept (PoC) or wild exploitation is currently available based on the provided data. π«
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Firebird installations running versions **older than** 3.0.14, 4.0.7, or 5.0.4. Check if external engine plugins are enabled and if input validation is missing for engine names. π
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: **Yes**. Patches are available in: β’ v3.0.14 β’ v4.0.7 β’ v5.0.4 π Refer to GitHub Security Advisories for details.
Q9What if no patch? (Workaround)
π οΈ **No Patch Workaround**: Disable external engine plugins if not needed. Implement strict input validation to reject `..` and path separators in engine names.β¦
β‘ **Urgency**: **High**. CVSS Score indicates Critical impact. Since it allows RCE with low effort (if authenticated), immediate patching to the latest stable versions is strongly recommended. π
