Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A critical **Stack-based Buffer Overflow** in Tenda WH450. ๐ฅ **Consequences**: Attackers can overwrite memory, leading to **Remote Code Execution (RCE)**.โฆ
๐ก๏ธ **Root Cause**: **CWE-121** (Stack-based Buffer Overflow). ๐ **Flaw**: Improper handling of the `page` parameter in the `/goform/NatStaticSetting` endpoint. Input exceeds buffer limits, corrupting the stack.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected Product**: Tenda WH450 Wireless Access Point. ๐ **Vulnerable Version**: **1.0.0.18**. โ ๏ธ Other versions may be safe, but this specific build is confirmed vulnerable.
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: **Root/System Level**. ๐ **Data**: Full access to device data. ๐ **Impact**: Since CVSS is **High (H)** for C/I/A, hackers can execute arbitrary code, steal data, or crash the device remotely.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. ๐ซ **Auth**: No authentication required (`PR:N`). ๐ฑ๏ธ **UI**: No user interaction needed (`UI:N`). ๐ **Vector**: Network accessible (`AV:N`). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exploit**: **YES**. ๐ **Source**: GitHub PoCs available (e.g., `z472421519/BinaryAudit`). ๐ **Status**: Technical descriptions and reproduction steps are public. Wild exploitation is possible.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Tenda WH450 devices running firmware **1.0.0.18**. ๐ก **Detection**: Look for requests to `/goform/NatStaticSetting` with oversized `page` parameters.โฆ
๐ฉน **Official Fix**: Data does not list a specific patch version. ๐ **Note**: Published Dec 23, 2025. Check Tenda's official support site for firmware updates > 1.0.0.18. ๐ Update immediately if available.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If no patch, **disable remote management** or block access to `/goform/NatStaticSetting` via firewall rules. ๐ Isolate the device on a segmented network to prevent lateral movement.โฆ
๐ฅ **Urgency**: **CRITICAL**. ๐ **Priority**: **P1**. With **CVSS 9.1**, **No Auth**, and **Public PoC**, this is an immediate threat. Patch or isolate **NOW**. โณ Time is of the essence.
