Published 12 Oct 2026 · NVD status: Undergoing Analysis · AI triage by gemini-3.8-flash

6.6Medium

Attack vector: Local
Complexity: Low
Privileges needed: Low
User interaction: Required
Impact: High impact on confidentiality, integrity
Weakness: CWE-732

Impact

Local attackers on shared Unix hosts can steal private keys generated by winpr-makecert. They need local account access and rely on a target user running the key generation tool.

Root cause

The winpr-makecert utility creates unencrypted private key files with overly permissive world-readable permissions and protects PFX files with a hard-coded default password.

Affected systems

FreeRDP 2.0.0 before 3.32.0 on Unix hosts

CVSS v3.1 · CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N

Fix & remediation

Upgrade FreeRDP to version 3.32.0 or later. If patching immediately is not possible, restrict permissions on existing generated keys and PFX files using 'chmod 600 <keyfile>'.

shell

$ sudo apt-get update && sudo apt-get install --only-upgrade freerdp2-x11

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?

NVD description

FreeRDP from 2.0.0 before 3.32.0 contains an insecure permission vulnerability in winpr-makecert that creates unencrypted private keys without owner-only file modes. Local users on multi-user Unix hosts can read world-readable key files or open PFX files protected by the hard-coded default password to steal private keys.
