CVE-2025-41278
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNozomi Networks Labs identified a CWE-125: Out-of-bounds Read in Waterfall WF-500 RX Host in version 7.10.0.0 R2601141040 that allows attackers with access to the TX Host to execute code on the RX Host.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn out-of-bounds read vulnerability (CWE-125) in the Waterfall WF-500 RX Host version 7.10.0.0 R2601141040 allows an attacker who has compromised the TX Host to read memory beyond buffer boundaries on the RX Host, potentially leading to arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Waterfall Wf 500 firmware version on the RX HostAccess the RX Host management interface or check the firmware version via the device's system information or CLI command that displays the current firmware build (e.g., 'show version' or similar device-specific command)Affected if The installed firmware version is 7.9.1.0_r2502171040 or any version lower (e.g., 7.8.x, 7.7.x, etc.)
-
Confirm the device is functioning as an RX HostCheck the device role or configuration within the Waterfall Security gateway setup to verify it is configured as the RX Host componentAffected if The device is configured as the RX Host in a Waterfall WF-500 deployment
-
Verify network connectivity between TX Host and RX HostInspect network configuration, firewall rules, or access control lists to determine if the TX Host has network access to the RX HostAffected if The TX Host can directly communicate with the RX Host over the network without proper isolation or strict access controls
-
Check if the vulnerability-affected TX-to-RX communication path is enabledReview the Waterfall gateway configuration to see if the TX Host-to-RX Host communication channel or module is active and permittedAffected if The TX Host is granted network access to communicate with the RX Host, enabling the attack vector for the out-of-bounds read
A user is affected if the RX Host is running firmware version 7.9.1.0_r2502171040 or lower AND the TX Host has network access to the RX Host, allowing the out-of-bounds read to be exploited.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-provided patch for version 7.10.0.0; ensure strict network segmentation between TX and RX hosts to limit attack surface, as exploitation requires prior access to the TX Host.
