AI Analysis
Technical Summary
The vulnerability CVE-2026-10192 affects Tenda W12 version 3.0.0.7(4763) and is caused by a stack-based buffer overflow in the set_local_time_0 function within the /bin/httpd executable. Manipulating the Time argument improperly triggers this overflow, allowing remote attackers to potentially execute arbitrary code or cause denial of service. The CVSS 4.0 base score is 8.7, reflecting network attack vector, low complexity, no user interaction, and high impact on confidentiality, integrity, and availability. No official patch or vendor advisory is currently available, and the exploit code is publicly accessible.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary code or disrupt the device's normal operation, impacting confidentiality, integrity, and availability of the affected device. Given the remote attack vector and high impact metrics, this poses a significant risk to affected Tenda W12 devices running the specified firmware version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting network exposure of the affected device, such as restricting remote access to the management interface. Monitor vendor communications for updates and apply patches promptly once available.
