CVE-2023-40265
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 · uneditedAn issue was discovered in Atos Unify OpenScape Xpressions WebAssistant V7 before V7R1 FR5 HF42 P911. It allows authenticated remote code execution via file upload.
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 · high confidenceThis is an authenticated remote code execution vulnerability in Atos Unify OpenScape Xpressions WebAssistant. Attackers with valid credentials can exploit insufficient file upload validation to upload malicious files that get executed on the server, potentially giving them full control of the affected system.

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.
-
Confirm OpenScape Xpressions WebAssistant is deployedInventory your environment for installations of Atos/Mitel Unify OpenScape Xpressions, specifically the WebAssistant component. Check server inventories or consult with system administrators responsible for unified communications infrastructure.Affected if The product is present in your environment
-
Verify WebAssistant web interface is accessibleAttempt to access the WebAssistant URL path (typically /WebAssistant or similar) on your OpenScape Xpressions server from a network location. Check if the service is listening on HTTP/HTTPS ports.Affected if The WebAssistant interface responds and is network-accessible
-
Determine the installed version of OpenScape XpressionsLog into the WebAssistant admin interface or check system documentation, release notes, or installed software inventory for the exact version string (e.g., 7.0, 7r1_fr1, etc.). Consult vendor documentation for version location if unclear.Affected if You obtain a specific version number from the installation
-
Compare version against affected rangeCheck if your installed version falls within >= 7.0 and < 7r1_fr5_hf42_p911. If your version is 7r1_fr5_hf42_p911 or later, the vulnerability is patched.Affected if The version is 7.0 or any 7.x release prior to 7r1_fr5_hf42_p911
You are affected if OpenScape Xpressions WebAssistant is running and the installed version is 7.0 or later but earlier than 7r1_fr5_hf42_p911.
