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 · unedited
xrdp is an open source RDP server. In versions through 0.10.5, xrdp does not implement verification for the Message Authentication Code (MAC) signature of encrypted RDP packets when using the "Classic RDP Security" layer. While the sender correctly generates signatures, the receiving logic lacks the necessary implementation to validate the 8-byte integrity signature, causing it to be silently ignored. An unauthenticated attacker with man-in-the-middle (MITM) capabilities can exploit this missing check to modify encrypted traffic in transit without detection. It does not affect connections where the TLS security layer is enforced. This issue has been fixed in version 0.10.6. If users are unable to immediately upgrade, they should configure xrdp.ini to enforce TLS security (security_layer=tls) to ensure end-to-end integrity.

Recommended fix High confidence

xrdp v0.10.6

  1. 1. Check the current installed version of xrdp (e.g., `xrdp -v` or `rpm -q xrdp` / `dpkg -l xrdp`)
  2. 2. Upgrade xrdp to version 0.10.6 or later using your system's package manager (e.g., `apt-get update && apt-get install xrdp` or `yum update xrdp`)
  3. 3. If building from source, download v0.10.6 from https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.6 and compile/install
  4. 4. Restart the xrdp service (e.g., `systemctl restart xrdp`)
  5. 5. Verify the new version is installed and running
