MITRE ATT&CK
2 techniques across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | High risk for affected devices (CVSS 8.6). While requiring authentication, default/weak router credentials are commonly unchanged. EOL status means no patches will be released, leaving affected devices permanently vulnerable. |
| Exploit ScenarioDerived | An attacker uses default credentials to access the router admin panel, navigates to Parental Control, and injects OS commands through the configuration parameters. The commands execute with root privileges on the router, enabling traffic interception and network pivot. |

2DescriptionCVE.org
The authenticated remote command execution (RCE) vulnerability exists in the Parental Control page on TP-Link Archer C7(EU) V2 and TL-WR841N/ND(MS) V9.
This issue affects Archer C7(EU) V2: before 241108 and TL-WR841N/ND(MS) V9: before 241108.
Both products have reached the status of EOL (end-of-life). It's recommending to
purchase the new product to ensure better performance and security. If replacement is not an option in the short term, please use the second reference link to download and install the patch(es).
Executive ViewAI
CVE-2025-9377 presents significant security risk, a OS command injection vulnerability rated CVSS 8.6. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. This vulnerability is actively exploited in the wild (KEV-listed) and requires immediate remediation. Immediate patching is required per CISA KEV mandate.
Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.
