Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: CVE-2025-15045 is a **Stack-based Buffer Overflow** in Tenda WH450. π₯ **Consequences**: Attackers can crash the system or execute arbitrary code, leading to total device compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-121** (Stack-based Buffer Overflow). The flaw lies in the **HTTP Request Handler** processing the `/goform/Natlimit` parameter `page`. Improper bounds checking allows stack corruption.
π **Impact**: **Critical** (CVSS 9.8). Hackers gain **High** Confidentiality, Integrity, and Availability impact. Potential for **Remote Code Execution (RCE)** with no authentication required.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. Network-accessible, Low complexity, **No Privileges** needed, No User Interaction required. Easy to exploit!
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Exploit Status**: **YES**. Public PoCs exist on GitHub (`z472421519/BinaryAudit`). π See `Natlimit/Natlimit.md` for reproduction steps. Wild exploitation is possible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Tenda WH450 devices running **v1.0.0.18**. Test the `/goform/Natlimit` endpoint with oversized `page` parameters to trigger buffer overflow. π΅οΈββοΈ
π§ **Workaround**: If no patch, **disable remote management**. Restrict access to the admin interface via **Firewall rules**. Monitor logs for abnormal `/goform/Natlimit` requests. π
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. High CVSS score + Public PoC + No Auth needed. **Patch immediately** or isolate the device. Do not ignore! β±οΈ
