CVE-2026-2192 Details
Description
A security vulnerability has been detected in Tenda AC9 15.03.06.42_multi. Affected by this vulnerability is the function formGetRebootTimer. Such manipulation of the argument sys.schedulereboot.start_time/sys.schedulereboot.end_time leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda AC9 router, specifically in the firmware version 15.03.06.42_multi. The issue arises in the 'formGetRebootTimer' function, where the application improperly validates input for the 'sys.schedulereboot.start_time' and 'sys.schedulereboot.end_time' configuration fields. This lack of proper bounds checking allows an attacker to manipulate these fields with excessively long strings, leading to a stack overflow that can crash the web service or cause it to repeatedly restart. In severe cases, this vulnerability could potentially be exploited to execute arbitrary code remotely.
