Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Buffer Overflow in UTT HiPER 810 router. ๐ **Consequences**: Full system compromise. High CVSS score (Critical) means attackers can steal data, modify settings, or crash the device completely.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-120 (Buffer Copy without Checking Size). ๐ **Flaw**: Improper handling of the `passwd1` parameter in the `/goform/setSysAdm` endpoint. Unsafe string operations lead to memory corruption.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected Product**: UTT HiPER 810 Smart Broadband Router. ๐ **Vulnerable Version**: Specifically **1.7.4-141218**. Check your firmware version immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Power**: Remote Code Execution (RCE). ๐ **Impact**: Complete loss of Confidentiality, Integrity, and Availability.โฆ
โก **Threshold**: LOW. ๐ **Access**: Network Vector (AV:N). No authentication required (PR:N). No user interaction needed (UI:N). Anyone on the network can trigger this exploit instantly.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Exploit Status**: YES. ๐ **Evidence**: Public PoCs and technical descriptions exist on GitHub and VulDB. Wild exploitation is highly likely given the low barrier to entry.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for UTT HiPER 810 devices. ๐งช **Test**: Attempt to send malformed payloads to `/goform/setSysAdm` via the `passwd1` parameter. Use vulnerability scanners configured with CVE-2026-1162 signatures.
Q8Is it fixed officially? (Patch/Mitigation)
๐ฉน **Patch Status**: Data does not confirm an official vendor patch yet. โ ๏ธ **Action**: Monitor UTT (่พๆณฐ) official channels for firmware updates. Currently, rely on mitigation strategies.
Q9What if no patch? (Workaround)
๐ **Workaround**: Block external access to the router's management interface. ๐ซ **Filter**: Restrict access to `/goform/setSysAdm` via firewall rules. Disable remote administration features if possible.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Priority**: CRITICAL. ๐จ **Urgency**: Immediate action required. With CVSS H:H:H and no auth needed, this is a high-risk vulnerability. Isolate affected devices until a patch is available.
