Lifecycle Timeline
3DescriptionCVE.org
A vulnerability was determined in Tenda F451 1.0.0.7. This affects the function fromP2pListFilter of the file /goform/P2pListFilter. This manipulation of the argument page causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.
AnalysisAI
Stack-based buffer overflow in Tenda F451 router (version 1.0.0.7) enables authenticated remote attackers to execute arbitrary code via malformed 'page' parameter in fromP2pListFilter function at /goform/P2pListFilter endpoint. Publicly available exploit code exists. Attack requires low-privilege authentication (PR:L) but no user interaction, yielding high confidentiality, integrity, and availability impact on vulnerable device.
Technical ContextAI
CWE-119 buffer overflow in fromP2pListFilter function fails to validate 'page' parameter length before stack copy operation. CVSS 4.0 vector indicates network-accessible attack surface with low complexity (AC:L, AT:N). Affects embedded router firmware without modern memory protections typical of SOHO devices.
RemediationAI
No vendor-released patch identified at time of analysis. Tenda has not published security advisories addressing CVE-2026-5992 on official support channels (https://www.tenda.com.cn/). Recommended immediate mitigations: disable remote administration interfaces, restrict administrative access to trusted internal networks only via firewall rules, implement network segmentation isolating IoT devices. Monitor vendor advisory page for future firmware updates. Consider replacing device if vendor does not issue patch within reasonable timeframe, as publicly disclosed exploit increases attack likelihood. VulDB tracking: https://vuldb.com/vuln/356546
