CVE-2025-4740
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 · uneditedA vulnerability was found in BeamCtrl Airiana up to 11.0. It has been declared as problematic. This vulnerability affects unknown code of the file coef. The manipulation leads to deserialization. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used.
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 confidenceA deserialization vulnerability exists in BeamCtrl Airiana up to version 11.0 in the 'coef' file. The vulnerability is locally exploitable and allows manipulation through deserialization. The exploit has been publicly disclosed.

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.
-
Verify BeamCtrl Airiana installationLocate the BeamCtrl Airiana installation directory or executable on the system. Common locations may include Program Files, installation directories, or application-specific paths. Check for presence of Airiana binaries or configuration files.Affected if BeamCtrl Airiana software is found on the system
-
Confirm installed version numberAccess the product version information through the application UI, about dialog, or check version metadata in installation files. Compare the version against the affected range: version 11.0 and below.Affected if Installed version is 11.0 or lower
-
Locate the coef fileSearch for a file named 'coef' within the BeamCtrl Airiana installation directory or associated data/config folders. This file typically stores coefficient data and may be in text, binary, or serialized format.Affected if The coef file exists in the installation or data directory
-
Check coef file deserialization usageInspect the contents and configuration of the coef file to determine if it uses deserialization mechanisms. Look for serialized data structures, magic bytes, or configuration indicating deserialization is enabled for reading coef data.Affected if The coef file utilizes deserialization for loading data or the application reads coef data using deserialization methods
-
Verify local access to coef fileConfirm that local users have read or write access to the coef file, as the vulnerability is described as locally exploitable. Check file permissions and access controls.Affected if Local users can modify or supply a malicious coef file
If BeamCtrl Airiana is installed at version 11.0 or lower and the application uses deserialization to read the coef file with accessible file permissions, the environment is affected by CVE-2025-4740.

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 dataContact BeamCtrl for the fixed version and apply any available patches; otherwise, review and sanitize the deserialization logic in the coef file to use safe deserialization methods.
