Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Path Traversal in WAVLINK AC3000. ๐ **Consequences**: Attackers can access files outside the intended directory, leading to severe data leaks or system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-22 (Path Traversal). ๐ **Flaw**: The firmware fails to properly sanitize user input, allowing directory traversal sequences (e.g., `../`) to escape restricted folders.
๐ **Privileges**: High Impact (CVSS H). ๐ **Data**: Full access to Confidentiality, Integrity, and Availability. Hackers can read sensitive configs, logs, or upload malicious files.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Auth Required**: Yes (PR:H). ๐ง **Threshold**: Medium. Attackers need valid credentials to exploit this, but the attack complexity is Low (AC:L).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: No specific PoC listed in data. ๐ **Source**: Referenced by Talos Intelligence (TALOS-2024-2057). Wild exploitation risk exists due to low complexity.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for WAVLINK AC3000 devices. ๐งช **Test**: Look for unhandled directory traversal inputs in web interfaces if authenticated. Use vulnerability scanners targeting CWE-22.
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Fix**: Update firmware to a version newer than V5030.210505. ๐ฅ **Action**: Check Wavlink's official support page for security patches immediately.
Q9What if no patch? (Workaround)
๐ซ **No Patch?**: Restrict network access to the router. ๐ **Mitigation**: Change default passwords, disable remote management, and isolate the device on a VLAN.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: HIGH. ๐ **Priority**: Patch immediately. CVSS Score indicates Critical impact on CIA triad. Do not ignore this vulnerability.
