TP-Link has acknowledged multiple severe vulnerabilities impacting Aginet networking devices managed by ISPs, including mesh systems, routers, PON units, and xDSL modems This article explores router filesystem cve. . These flaws could enable unauthorized access via network penetration, elevate privileges, steal sensitive data, read device files, and execute OS commands.
An attacker on an adjacent network can send specially crafted requests to exploit unauthenticated functions without providing valid credentials. CVE-2025-30240 involves a medium-severity arbitrary file-read flaw affecting the USB HTTPS access path, due to improper handling of symbolic links on external USB storage by certain devices. A physical attacker can exploit this vulnerability by creating a malicious symbolic link on supported media and gaining elevated privileges to read sensitive files in the router's filesystem.
CVE-2025-30237 Authentication bypass High CVE-2025-30238 Privilege escalation High CVE-2025-30239 Sensitive data exposure High CVE-2025-30240 Arbitrary file read Medium The final issue, CVE-2025-30241, is an OS command injection vulnerability with a severity rating of 8.6. CVE-2025-30237, CVE-2025-30238, and CVE-2025-30239 contribute to the overall security risks associated with this issue, while CVE-2025-30241 specifically addresses a critical vulnerability that could lead to elevated privileges and unauthorized access. As several flaws necessitate local or neighboring network access, users are advised to restrict exposure of management interfaces, utilize strong, distinct administrator credentials, disable unnecessary remote management features, and keep untrusted individuals off the local network.
