CVE-2025-34319: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in TOTOLINK N300RT
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.
AI Analysis
Technical Summary
CVE-2025-34319 is an OS command injection vulnerability (CWE-78) affecting TOTOLINK N300RT wireless routers with firmware versions before V3.4.0-B20250430. The flaw exists in the Boa formWsc handling functionality, where the targetAPSsid request parameter is improperly neutralized, allowing unauthenticated attackers to execute arbitrary OS commands remotely. The vulnerability has a critical CVSS 4.0 base score of 9.3, reflecting its high impact and ease of exploitation without authentication.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary operating system commands on the affected device, potentially leading to full compromise of the router. This can result in unauthorized control over network traffic, device configuration, and further network attacks. No known exploits are reported in the wild so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the router's management interfaces from untrusted networks to reduce exposure. Monitor vendor channels for firmware updates addressing this vulnerability.
