CyberRota Analysis
AI-GeneratedVersions of xrdp prior to 0.10.6.1 are vulnerable to a flaw in the processing of RDP Confirm Active PDU, allowing remote, unauthenticated attackers to exploit insufficient length validation during capability negotiation. This could lead to out-of-bounds memory reads and potential Denial of Service, although the impact is mitigated as only individual connections may be affected. Organizations using xrdp should prioritize upgrading to the latest version to mitigate this risk.

Original NVD Description
xrdp is an open source RDP server. Versions 0.10.6 and prior contain a vulnerability concerning the processing of RDP Confirm Active PDU, where during the capability negotiation phase, the parser did not perform sufficient length validation for specific capability sets. A remote, unauthenticated attacker could potentially exploit this flaw by sending a specially crafted RDP packet containing malformed capability data. Due to missing bounds checks, the xrdp process may perform out-of-bounds memory reads, which can result in the termination of the service (Denial of Service). However, since xrdp forks a new process for each connection by default, an out-of-bounds read causing a process crash is unlikely to bring down the entire xrdp service. This issue has been fixed in version 0.10.6.1.
