Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Buffer Overflow in UTT 512W Router. π₯ **Consequences**: Full system compromise. The `strcpy` function in `/goform/formConfigFastDirectionW` mishandles the `ssid` parameter, leading to memory corruption.β¦
π‘οΈ **Root Cause**: CWE-120 (Buffer Copy without Checking Size of Input). π **Flaw**: Unsafe use of `strcpy` on the `ssid` argument. No bounds checking allows oversized input to overwrite adjacent memory.
Q3Who is affected? (Versions/Components)
π¦ **Affected Product**: UTT (Aggressive) 512W Wireless Router. π **Versions**: v3.1.7.7-171114 and **earlier** versions. If you are running this legacy firmware, you are vulnerable.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Remote Code Execution (RCE). π **Impact**: High (CVSS 9.8). Hackers can steal data, modify configurations, and take full control of the device without restriction.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: LOW. π **Access**: Network Vector (AV:N). β οΈ **Auth**: None Required (PR:N). No login or user interaction needed. Any attacker on the network can trigger this.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: Yes. π **Evidence**: References include GitHub issues (maximdevere/CVE2#7) and VDB entries. While specific PoC code isn't in the snippet, the vulnerability is well-documented and likely exploitable.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for UTT 512W devices. π **Verify**: Check firmware version. If it is `<= 3.1.7.7-171114`, you are at risk. Look for exposure of the `/goform/formConfigFastDirectionW` endpoint.
π **No Patch?**: Isolate the device. π« **Mitigation**: Block external access to the router's management interface. Restrict network access to trusted IPs only. Disable remote management features.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: CRITICAL. β±οΈ **Priority**: Patch Immediately. With CVSS 9.8 and no auth required, this is a high-priority threat. Do not delay updating your UTT 512W routers.
