CVE-2025-14879 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Wh450 Firmware. Its CVSS base score is 8.9 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-14879 is a stack-based buffer overflow vulnerability affecting the Tenda WH450 router on firmware version 1.0.0.18. The flaw resides in an unknown function within the /goform/onSSIDChange file of the HTTP Request Handler component, where manipulation of the ssid_index argument triggers the overflow. It is associated with CWEs-119 and CWE-121.
Attackers can exploit this vulnerability remotely over the network without authentication or user interaction, requiring only low attack complexity. Successful exploitation grants high impacts across confidentiality, integrity, and availability (CVSS v3.1 base score of 9.8: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), potentially allowing arbitrary code execution on the device.
A proof-of-concept exploit is publicly available on GitHub (https://github.com/z472421519/BinaryAudit/blob/main/PoC/BOF/Tenda_WH450/onSSIDChange/onSSIDChange.md), and further details appear in VulDB entries (https://vuldb.com/?ctiid.337370, https://vuldb.com/?id.337370, https://vuldb.com/?submit.715362). Practitioners should monitor the Tenda website (https://www.tenda.com.cn/) for firmware patches or mitigation guidance, as the public PoC increases the risk of active attacks.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and analysis can discover stack-buffer overflows before deployment.
Input validation directly stops untrusted data from exceeding stack buffer bounds.
Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.
Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.
