Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Vociferous < 4.4.2 has a critical **Access Control Error**. The `export_file` route ignores filename validation.β¦
π‘οΈ **Root Cause**: **CWE-22** (Path Traversal). The flaw lies in `src/api/system.py`. The API fails to validate user-supplied filenames and has **loose CORS configuration**.β¦
π₯ **Affected**: Users of **Vociferous** by **WanderingAstronomer** (Andrew Brown). Specifically, all versions **prior to 4.4.2**. This is a cross-platform offline speech-to-text tool.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With **CVSS 9.8 (Critical)**, attackers get **Full Control**. They can: 1. Read sensitive files (High Confidentiality). 2. Modify system files (High Integrity). 3.β¦
π **Exploitation Threshold**: **VERY LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. Network accessible, Low complexity, **No Privileges** needed, No User Interaction required. It's a 'one-click' remote exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π¦ **Public Exploit**: **No PoC provided** in the data. However, given the low CVSS score and clear root cause (CWE-22), wild exploitation is **highly likely** soon. The advisory link is public, so details are known.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Vociferous** services. Check if the version is **< 4.4.2**. Look for the `/export_file` API endpoint. Test if you can send `../` in filename parameters.β¦
β **Official Fix**: **Yes**. The vendor released an advisory (GHSA-7cpr-frgj-h85v). The fix is included in **Version 4.4.2**. You must upgrade to this version or later to resolve the issue.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: 1. **Block** external access to the Vociferous API. 2. Implement strict **WAF rules** to block `../` sequences. 3. Restrict CORS to specific trusted origins. 4.β¦
π₯ **Urgency**: **CRITICAL / IMMEDIATE ACTION**. CVSS 9.8 is near-maximum. Remote code execution/file write is possible without auth. **Patch immediately** to version 4.4.2+ to prevent system takeover.
