CVE-2025-15216
Published: 30 December 2025
Description
A vulnerability was identified in Tenda AC23 16.03.07.52. This impacts the function fromSetIpMacBind of the file /goform/SetIpMacBind. Such manipulation of the argument bindnum leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is publicly…

Mitigating Controls (NIST 800-53 r5)AI
Directly requires identification, reporting, and correction of the stack-based buffer overflow flaw in the fromSetIpMacBind function via firmware patching.
Mandates validation of the bindnum argument in /goform/SetIpMacBind to prevent improper restriction of operations within memory bounds.
Implements memory safeguards such as stack canaries or non-executable stacks to mitigate remote exploitation of the stack-based buffer overflow.
Security SummaryAI
CVE-2025-15216 is a stack-based buffer overflow vulnerability affecting the Tenda AC23 router on firmware version 16.03.07.52. The flaw resides in the fromSetIpMacBind function within the /goform/SetIpMacBind file, where improper handling of the bindnum argument allows overflow conditions. It is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow), and was published on 2025-12-30.
The vulnerability enables remote exploitation (AV:N) by attackers with low privileges (PR:L), requiring low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation can result in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), earning a CVSS v3.1 base score of 8.8 in an unchanged scope (S:U). A public exploit is available, facilitating potential abuse.
Advisories referenced on VulDB (ctiid.338601, id.338601, submit.725447) and a Notion site detail the issue, while the Tenda website (tenda.com.cn) serves as a source for vendor guidance on patches or mitigations.
