xrdp Vulnerability Allows Local Privilege Escalation to Root
The National Vulnerability Database has detailed CVE-2026-32107, a critical vulnerability in the xrdp open-source RDP server. Versions prior to 0.10.5 suffer from an error in the privilege drop process. This flaw allows an authenticated local attacker to escalate their privileges to root, enabling arbitrary code execution on the affected system. While an additional exploit step is required, the path to a full system compromise is significantly shortened.
This vulnerability, rated HIGH with a CVSS score of 8.8, impacts systems running vulnerable xrdp versions. The National Vulnerability Database notes the Common Weakness Enumeration as CWE-273, highlighting improper privilege management. Defenders should prioritize patching or upgrading xrdp to version 0.10.6, which addresses this security flaw. Unpatched systems present a clear, exploitable target for attackers already possessing local access.
What This Means For You
- If your organization uses xrdp for RDP access, immediately verify your version. You must upgrade to xrdp 0.10.6 or later to mitigate this privilege escalation vulnerability. Audit systems for unauthorized local user accounts and review logs for signs of privilege escalation attempts.
