It is possible to initiate the attack remotely. The exploit is publicly available and might 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, all running specific firmware versions. The vulnerability arises in the 'langSwitchByBBS' function of the '/goform/langSwitchByBBS' file, where the 'langSelectionOnly' parameter is manipulated, leading to a buffer overflow. This vulnerability can be exploited remotely, causing the router to crash and disrupt services. Additionally, the overflow could potentially be leveraged to execute arbitrary code.
