CVE-2025-9481 Details
Description
A security vulnerability has been detected in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function setIpv6 of the file /goform/setIpv6. The manipulation of the argument tunrd_Prefix leads to stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow vulnerability has been identified in Linksys RE6250, RE6300, RE6350, RE6500, RE7000, and RE9000 routers running specific firmware versions. The vulnerability arises in the 'setIpv6' function of the '/goform/setIpv6' file, where the 'tunrd_Prefix' argument can be manipulated, leading to remote exploitation. This vulnerability allows attackers to execute arbitrary code by overwriting the return address of the function, causing the router to crash and disrupt service.
