Critical WatchGuard Fireware OS Flaw Enables Remote Code Execution - Against Invaders - Notícias de CyberSecurity para humanos.

A critical vulnerability (CVSS4.0 9.3) inWatchGuard Fireware OShas been identified that could allow a threat actor to remotely execute arbitrary code.

The bug, tracked as CVE-2025-9242, is an out-of-bounds write vulnerability affecting mobile user VPN with IKEv2 and the branch office VPN (BOVPN) using IKEv2 when configured with a dynamic gateway peer.

The WatchGuard advisory noted that if the Firebox security platform was previously configured with the above VPN and IKEv2 gateway peers it could still be vulnerable.

The vulnerability affects Fireware OS 11.10.2 up to and including 11.12.4_Update1, 12.0 up to and including 12.11.3 and 2025.1.

WatchGuard’s Firebox is a next-generation firewall (NGFW) that acts as a security gateway, controlling traffic between external and trusted networks, and includes advanced features like intrusion prevention, anti-spam and content filtering.

It can be deployed as a physical appliance, in the cloud or as a virtual machine.

The Shadowserver foundation noted that based on IP data scans, there could be over 71,000 vulnerable devices as of October 17.

Details on the vulnerability are now available on the US National Vulnerability Database (NVD) and WatchGuard has also published a security advisory.

If the Firebox is only configured with Branch Office VPN tunnels to static gateway peers and the owner is not able to immediately upgrade the device to a version of Fireware OS with the vulnerability resolution, WatchGuard has provided recommendations for a temporary workaround.

In its advisory, WatchGuard noted that it recommends BOVPN secure access policies are configured with a narrower scope to handle incoming VPN traffic, due to increasing attacks against exposed VPNs that target a wide range of vendors.

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.
