CVE-2026-7078: Buffer Overflow in Tenda F456
CVE-2026-7078 is a high-severity buffer overflow vulnerability in the Tenda F456 router firmware version 1. 0. 0. 5. The flaw exists in the fromSetIpBind function within the /goform/SetIpBind component of the httpd service. Remote attackers can exploit this vulnerability by manipulating the 'page' argument, potentially causing a buffer overflow. Although an exploit has been publicly released, there are no confirmed reports of exploitation in the wild. No official patch or remediation guidance has been provided by the vendor as of the published date.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the fromSetIpBind function of the /goform/SetIpBind endpoint in Tenda F456 firmware 1.0.0.5. The issue arises from improper handling of the 'page' argument, allowing remote attackers to trigger a buffer overflow condition. The vulnerability is remotely exploitable without user interaction and requires low attack complexity and privileges. The CVSS 4.0 base score is 8.7, indicating high severity with high impact on confidentiality, integrity, and availability. No official fix or patch has been documented, and the product is not a cloud service, so remediation depends on vendor action.
Potential Impact
Successful exploitation of this vulnerability can lead to a buffer overflow, which may allow remote attackers to execute arbitrary code or cause denial of service on the affected device. The high CVSS score reflects significant potential impact on device confidentiality, integrity, and availability. Since the exploit code is publicly available, the risk of attacks may increase. However, there are no confirmed reports of exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been published by Tenda as of the vulnerability disclosure date. Users should monitor vendor communications for updates and consider restricting remote access to the affected device until a patch is available.
