CVE-2026-6988 Details
Description
A flaw has been found in Tenda HG10 HG7_HG9_HG10re_300001138_en_xpon. This issue affects the function formRoute of the file /boaform/formRouting of the component Boa Service. This manipulation of the argument nextHop causes buffer overflow. It is possible to initiate the attack remotely. The exploit has been published and may be used.
A stack-based buffer overflow vulnerability has been identified in the Tenda HG10 router, specifically in the Boa web service component. This issue arises in the 'formRoute' function within the '/boaform/formRouting' file, on the HG7_HG9_HG10re_300001138_en_xpon firmware version. The vulnerability is triggered by manipulating the 'nextHop' parameter, which is not properly validated before being copied into a stack buffer. This flaw can be exploited remotely, potentially leading to a denial-of-service condition by crashing the Boa service, and may also allow for arbitrary code execution due to the nature of the stack corruption.
