Tenda · Jd12L · CVE-2026-13515
**Name of the Vulnerable Software and Affected Versions**
Tenda JD12L version 16.03.53.23
**Description**
A stack-based buffer overflow occurs in the `formSetPPTPServer()` function within the `/goform/SetPptpServerCfg` file. This issue is triggered by the manipulation of the `startIp` argument, allowing a remote attacker to execute the attack.
