No exploitation status, affected product details, or impact scope can be determined from available data.
Remote denial of service in xrdp (the open-source Microsoft RDP server from neutrinolabs) before v0.10.6.1 allows unauthenticated remote attackers to trigger an infinite loop (CWE-835) that exhausts CPU and hangs the service. No exploit code has been publicly identified and the flaw is not in CISA KEV, but the CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N, availability-only) reflects that it is reachable pre-authentication over the network against default RDP listeners. It was fixed alongside nine other vulnerabilities in the coordinated v0.10.6.1 release published 2026-07-06.
Heap-based buffer overflow in neutrinolabs xrdp (open-source RDP server for Linux/Unix) lets a low-privileged authenticated attacker corrupt heap memory over the network, achieving high-impact confidentiality, integrity, and availability compromise (CVSS 8.8), potentially arbitrary code execution in the xrdp process. Fixed in xrdp v0.10.6.1 (2026-07-06) via advisory GHSA-hh7r-2rmq-q4g4, one of ten CVEs patched in that release. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote unauthenticated heap buffer overflow in xrdp (the open-source Remote Desktop Protocol server from neutrinolabs) affects versions prior to v0.10.6.1 and is fixed alongside nine other vulnerabilities in that release. Per the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) a network attacker who can reach the RDP listener can corrupt heap memory without authentication or user interaction, with high impact to confidentiality, integrity and availability. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV.
Heap-based buffer overflow in xrdp 0.10.5 and earlier allows remote code execution after authentication via malicious EGFX graphics channel PDUs. Authenticated attackers can exploit insufficient validation of client-controlled size parameters to write beyond allocated heap buffers. Unauthenticated attackers can only trigger denial-of-service crashes. Vendor-released patch available in version 0.10.6. No active exploitation confirmed (not in CISA KEV), but heap overflows in remote services are high-value targets. Default non-privileged execution since 0.10.2 limits post-compromise impact.
Out-of-bounds read in xrdp 0.10.5 and earlier allows unauthenticated remote attackers to crash the RDP service or disclose memory contents during pre-authentication message parsing. The vulnerability (CWE-125) exploits insufficient buffer length validation in dynamic channel communication handling, affecting default installations exposed to network access. Fixed in version 0.10.6 per vendor advisory GHSA-92mr-6wpp-27jj. CVSS 8.7 reflects high availability impact; no active exploitation confirmed in CISA KEV at time of analysis, though public disclosure increases risk for internet-facing xrdp deployments.
Authenticated remote command execution in xrdp through version 0.10.5 allows users to execute arbitrary shell commands on the RDP server via an unsanitized AlternateShell parameter during session initialization. When AllowAlternateShell is enabled (the default configuration), xrdp passes client-supplied shell commands directly to /bin/sh -c without sanitization, bypassing normal session constraints. An authenticated RDP user can exploit this to run arbitrary commands in the context of their login session before the window manager starts, with no public exploit code identified at time of analysis.
Heap-based buffer overflow in xrdp 0.10.5 and earlier allows unauthenticated remote attackers to cause denial of service or memory corruption when the domain_user_separator configuration directive is explicitly enabled in xrdp.ini. An attacker sends a crafted RDP logon request with an excessively long username and domain name combination that overflows an internal buffer, corrupting adjacent memory regions. The vulnerability requires non-default configuration (domain_user_separator must be uncommented) and affects only systems with this setting enabled. Vendor-released patch: version 0.10.6.
Out-of-bounds read in xrdp RDP server versions ≤0.10.5 allows remote unauthenticated attackers to crash the service or disclose process memory by sending a malformed Confirm Active PDU during RDP capability negotiation. Attack complexity is low but requires user interaction. EPSS data not available; no CISA KEV listing or public POC identified at time of analysis. Vendor-released patch available in version 0.10.6 per GitHub security advisory GHSA-rvh9-9wm3-28c7.
Heap-based buffer overflow in xrdp's NeutrinoRDP module (versions ≤0.10.5) enables malicious downstream RDP servers or MitM attackers to achieve remote code execution or denial of service when proxying RDP sessions. Exploitation requires the victim xrdp server to have the non-default NeutrinoRDP module compiled and enabled (--enable-neutrinordp), and a user must initiate an RDP session through the affected proxy to a malicious server. EPSS data unavailable; no CISA KEV listing indicates targeted rather than widespread exploitation. Fixed in version 0.10.6.
Missing MAC signature verification in xrdp 0.10.5 and earlier allows man-in-the-middle attackers to modify encrypted RDP traffic without detection when Classic RDP Security layer is used. Unauthenticated network attackers with MITM position can alter packet contents in transit, achieving high integrity and confidentiality impact on both vulnerable and subsequent systems (CVSS 9.3, CVSS:4.0 with scope change). TLS security layer deployments are not affected. Vendor patch released in version 0.10.6. No active exploitation or public POC identified at time of analysis, but EPSS data unavailable for risk assessment.
Privilege escalation to root in xrdp 0.10.5 and earlier allows authenticated local attackers to execute arbitrary code due to improper error handling during privilege drop in the session execution component. The flaw requires low attack complexity and no user interaction (CVSS 8.8, AV:L/AC:L/PR:L/UI:N). Vendor-released patch available in xrdp v0.10.6. No public exploit or active exploitation confirmed at time of analysis, though CVSS scope change (S:C) indicates potential container/VM escape scenarios.
