Analysis

TOTOLINK N300RT wireless router firmware versions prior to V3.4.0-B20250430 (discovered in V2.1.8-B20201030.1539) contain an OS command injection vulnerability in the Boa formWsc handling functionality. An unauthenticated attacker can send specially crafted requests to trigger command execution via the targetAPSsid request parameter.

Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells. This vulnerability is classified as OS Command Injection (CWE-78).

Affected Products

Affected: V2

Remediation

Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
