CVE-2026-7029: Buffer Overflow in Tenda F456
CVE-2026-7029 is a high-severity buffer overflow vulnerability in Tenda F456 version 1. 0. 0. 5. It exists in the fromaddressNat function within the /goform/addressNat file. An attacker can remotely trigger this vulnerability by manipulating the menufacturer/Go argument, potentially leading to a buffer overflow. The exploit code is publicly available, increasing the risk of exploitation. No official patch or remediation guidance has been provided by the vendor as of the publication date.
AI Analysis
Technical Summary
This vulnerability affects Tenda F456 firmware version 1.0.0.5. The flaw is a buffer overflow in the fromaddressNat function of the /goform/addressNat endpoint, triggered by crafted input in the menufacturer/Go argument. The vulnerability can be exploited remotely without user interaction or elevated privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:N). The CVSS 4.0 base score is 8.7, reflecting high impact on confidentiality, integrity, and availability. Public exploit code is available, but there is no vendor-provided patch or official remediation at this time.
Potential Impact
Successful exploitation can lead to a buffer overflow, which may allow an attacker to execute arbitrary code or cause a denial of service on the affected device. The vulnerability impacts confidentiality, integrity, and availability with high severity. The attack can be performed remotely with low complexity and no user interaction, increasing the risk to exposed devices running the vulnerable firmware version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, affected users should consider disabling remote access to the vulnerable endpoint or isolating the device from untrusted networks to reduce exposure. Monitor vendor channels for updates and apply patches promptly once available.
