CyberRota Analysis
AI-GeneratedVersions of xrdp prior to 0.10.6.1 are vulnerable to a denial-of-service attack due to improper validation of the totalLength field in the RDP protocol control header, allowing unauthenticated remote attackers to send crafted packets that cause the xrdp process to enter an infinite CPU-bound loop. This can lead to service unavailability and potential system-wide resource exhaustion if multiple attacks occur simultaneously. Organizations using affected versions of xrdp should prioritize upgrading to the patched version to mitigate this high-severity vulnerability.

Original NVD Description
xrdp is an open source RDP server. In versions 0.10.6 and prior, a n issue was discovered where the software fails to properly validate the totalLength field within the RDP protocol control header during packet reception. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted packet that forces the xrdp process or thread into an infinite, CPU-bound loop. Because the internal pointer fails to advance and the deadlock prevention mechanism is bypassed for specific protocol data unit types, the process consumes excessive CPU resources indefinitely. This can render the xrdp service unavailable and potentially lead to system-wide resource exhaustion if multiple malicious connections are established. This issue has been fixed in version 0.10.6.1.
