TP-Link warns of critical command injection flaw in Omada gateways

Picus Blue Report 2025

TP-Link is warning of two command injection vulnerabilities inOmada gateway devices that could be exploited to execute arbitrary OS commands.

Omada gateways are marketed asfull-stack solutions (router, firewall, VPN gateway) for small to medium businesses, and are constantly increasing in popularity.

Although the two security issues lead to the same result when triggered, only one of them, identified as CVE-2025-6542 with a critical severity rating of 9.3, can be exploited by a remote attacker without authentication.

The second flaw is tracked asCVE-2025-6541 and received a lower severity score of 8.6. However, it can be exploited only if the attacker can log into the web management interface.

“An arbitrary OS command may be executed on Omada gateways by the user who can log in to the web management interface or by a remote unauthenticated attacker,” reads TP-Link’s advisory.

“Attackers may execute arbitrary commands on the device’s underlying operating system,” the company adds.

The risk the two vulnerabilities poses is significant as it can lead to a full compromise, data theft, lateral movement, and persistence.

CVE-2025-6541 and CVE-2025-6542 impact 13 Omada gateway models in the firmware versions listed below:

The vendor has released firmware updates that address the two problems and strongly recommends that users with impacted devices to apply the fixes and check the configurations after the upgrade to make sure that all settings remainas intended.

In a separate bulletin, TP-Link warned of two other severe flaws that could allow authenticated command injection and root access under certain conditions.

The first is CVE-2025-8750 (CVSS: 9.3), a command injection flaw that can be exploited by attackers holding admin passwords to access the Omada web portal.

The other one is CVE-2025-7851 (CVSS: 8.7), which could enable an attacker to obtain shell access with root privileges on the underlying OS, restricted to Omada’s privileges.

CVE-2025-7850 and CVE-2025-7851 impact all of the Omada gateway models listed in the table above.It is worth noting that the latest firmware release addresses all four vulnerabilities.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
