CVE-2026-35512: CWE-122: Heap-based Buffer Overflow in neutrinolabs xrdp
A heap-based buffer overflow vulnerability exists in neutrinolabs xrdp versions prior to 0. 10. 6 in the EGFX graphics dynamic virtual channel implementation. This occurs due to insufficient validation of client-controlled size parameters, allowing out-of-bounds writes via crafted PDUs. Exploitation before authentication can crash the server process, while exploitation after authentication may lead to remote code execution. The issue is fixed in version 0. 10. 6. Running xrdp as a non-privileged user can limit exploitation impact if immediate updating is not possible.
AI Analysis
Technical Summary
CVE-2026-35512 is a heap-based buffer overflow vulnerability in neutrinolabs xrdp (an open source RDP server) affecting versions before 0.10.6. The flaw exists in the EGFX dynamic virtual channel due to inadequate validation of client-supplied size parameters, enabling out-of-bounds memory writes through crafted protocol data units. This vulnerability allows unauthenticated attackers to cause a denial of service by crashing the process, and authenticated attackers may achieve remote code execution. The vulnerability is addressed in xrdp version 0.10.6.
Potential Impact
Successful exploitation can cause a denial of service via process crash without authentication and potentially remote code execution with authentication. This elevates the risk of unauthorized control over the xrdp server, impacting confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Upgrade xrdp to version 0.10.6 or later where this vulnerability is fixed. If immediate upgrade is not feasible, ensure xrdp runs as a non-privileged user (default since version 0.10.2) to reduce the impact of exploitation. Monitor vendor advisories for any additional guidance.
