Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Server-Side Template Injection (SSTI) via model metadata in **llama.cpp**. π₯ **Consequences**: Remote Code Execution (RCE). Attackers can hijack the server completely!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-76** (Improper Neutralization of Equivalent Special Elements). The flaw lies in how the system processes **model metadata**, allowing malicious templates to execute code.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **llama-cpp-python** by vendor **abetlen**. Specifically, versions vulnerable to SSTI via metadata injection. Check your GitHub advisories for exact version ranges.
Q4What can hackers do? (Privileges/Data)
π **Attacker Power**: Full **RCE**! High impact on Confidentiality, Integrity, and Availability. Hackers gain the same privileges as the application process. Total system compromise.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: **Low**. CVSS Vector: **AV:N/AC:L/PR:N/UI:R**. Network accessible, Low complexity, **No Privileges required**. However, it requires **User Interaction** (UI:R) to trigger.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: No specific PoC code listed in the data. However, the vulnerability is confirmed via GitHub Security Advisory (**GHSA-56xg-wfcc-g829**). Treat as exploitable.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **llama-cpp-python** installations. Check if you are processing untrusted model metadata. Look for the commit **b454f40** as a reference point for the fix.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: Yes! A fix commit exists: **b454f40a9a1787b2b5659cd2cb00819d983185df**. Update to the patched version immediately to mitigate the risk.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Mitigation**: Strictly sanitize/validate all **model metadata** inputs. Do not process untrusted models. Isolate the service running llama.cpp to limit blast radius.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. CVSS Score indicates Critical impact (H/H/H). Even with UI requirement, the ease of exploitation (L/AC) and network access (N) make this a priority patch.
