| Título | Totolink WA300 V5.2cu.7112_B20190227 OS Command Injection |
|---|
| Descripción | A security flaw exists in the `cstecgi.cgi` interface of certain TOTOLINK WA300 V5.2cu.7112_B20190227. When processing requests for the `setting/recvUpgradeNewFw` function, the firmware fails to validate user-supplied parameters before concatenating them into system commands. An attacker can leverage this by sending a crafted JSON request to achieve Root-level Remote Code Execution (RCE) without authentication. |
