CVE-2025-11586 Details
Description
A vulnerability was determined in Tenda AC7 15.03.06.44. This affects an unknown function of the file /goform/setNotUpgrade. This manipulation of the argument newVersion causes stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.
A stack-based buffer overflow vulnerability has been identified in the Tenda AC7 router, specifically in the firmware version 15.03.06.44. The issue arises in the POST /goform/setNotUpgrade interface, where the newVersion parameter is processed without proper input size validation. This lack of validation allows for the injection of excessively long strings, which can overflow the stack buffer and potentially lead to remote code execution or a device crash.
