Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the OS command injection vulnerability by requiring timely application of vendor-provided patches for affected TP-Link Omada products.
Prevents arbitrary OS command execution by enforcing input validation and error handling on network-facing interfaces vulnerable to CWE-78 injection.
Limits remote unauthenticated network access to the vulnerable router management interfaces through boundary protection controls.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
CVE enables unauthenticated remote exploitation of public-facing application (T1190) leading to arbitrary OS command execution on network devices (T1059.008).
NVD Description
An arbitrary OS command may be executed on the product by a remote unauthenticated attacker.
Deeper analysisAI
CVE-2025-6542 is a critical OS command injection vulnerability (CWE-78) with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), published on 2025-10-21T01:15:37.063. It affects TP-Link Omada networking products, including various router models listed under Omada routers, Omada Pro wired routers, and SOHO Festa gateways.
A remote unauthenticated attacker can exploit the vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation enables execution of arbitrary OS commands on the affected product, resulting in high impacts to confidentiality, integrity, and availability.
