CVE-2025-0501
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 in the native clients for Amazon WorkSpaces (when running PCoIP protocol) may allow an attacker to access remote sessions via man-in-the-middle.
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 man-in-the-middle vulnerability in the native Amazon WorkSpaces clients using the PCoIP protocol allows an attacker to intercept and gain unauthorized access to remote desktop sessions. The vulnerability stems from insufficient validation of the remote session connection, enabling session hijacking.

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.
-
Check if Amazon WorkSpaces client is installedOn Windows, check for the presence of the Amazon WorkSpaces client in the installation directory (typically C:\Program Files\Amazon Web Services, Inc\Amazon WorkSpaces\ or C:\Program Files (x86)\Amazon Web Services, Inc\Amazon WorkSpaces\). Look for the client executable file.Affected if The WorkSpaces client is present on the system.
-
Determine installed WorkSpaces client versionRight-click the Amazon WorkSpaces executable (commonly named Amazon WorkSpaces.exe or WorkSpaces.exe), select Properties, and check the File Version on the Details tab. Alternatively, run the client and look for version information in the About or Help section.Affected if The installed version matches or falls within an affected version range that is older than the patched version provided by Amazon.
-
Verify PCoIP protocol is in useOpen the WorkSpaces client settings or connection properties and confirm that PCoIP is selected as the session protocol. PCoIP is the default protocol for WorkSpaces, but verify this is not changed to another protocol.Affected if PCoIP protocol is selected or is the default active protocol for the WorkSpaces connection.
-
Assess network exposureDetermine whether WorkSpaces connections traverse untrusted networks (such as public WiFi, open internet) without VPN protection. Check network configuration and routing paths used when connecting to WorkSpaces.Affected if The client connects to WorkSpaces over untrusted or public networks without an encrypted VPN tunnel, making MITM attacks feasible.
You are affected if the Amazon WorkSpaces PCoIP client is installed with an unpatched version and connects to sessions over networks where a man-in-the-middle attack is possible.

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 dataUpdate all Amazon WorkSpaces PCoIP clients to the latest version provided by Amazon. Until patched, avoid untrusted networks and consider using VPN tunnels for WorkSpaces connections to reduce MITM exposure.
