| CVE-2013-1430 | Cri | 0.57 | 9.8 | 0.01 | Dec 16, 2016 | An issue was discovered in xrdp before 0.9.1. When successfully logging in using RDP into an xrdp session, the file ~/.vnc/sesman_${username}_passwd is created. Its content is the equivalent of the user's cleartext password, DES encrypted with a known key. | ||
| CVE-2017-16927 | Hig | 0.55 | 8.4 | 0.00 | Nov 23, 2017 | The scp_v0s_accept function in sesman/libscp/libscp_v0.c in the session manager in xrdp through 0.9.4 uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other… | ||
| CVE-2026-33689 | Cri | 0.52 | 9.1 | 0.00 | Apr 17, 2026 | xrdp is an open source RDP server. Versions through 0.10.5 have an out-of-bounds read vulnerability in the pre-authentication RDP message parsing logic. A remote, unauthenticated attacker can trigger this flaw by sending a specially crafted sequence of packets during the initial… | ||

In versions through 0.10.5, the session execution component did not properly handle an error during the privilege drop process. This improper privilege management could allow an authenticated local attacker to escalate privileges to root and… | ||

| CVE-2026-33145 | Med | 0.34 | 6.3 | 0.00 | Apr 17, 2026 | xrdp is an open source RDP server. Versions through 0.10.5 allow an authenticated remote user to execute arbitrary commands on the server due to unsafe handling of the AlternateShell parameter in xrdp-sesman. When the AllowAlternateShell setting is enabled (which is the default… | ||
| CVE-2008-5904 | 0.04 | — | 0.07 | Jan 15, 2009 | The rdp_rdp_process_color_pointer_pdu function in rdp/rdp_rdp.c in xrdp 0.4.1 and earlier allows remote RDP servers to have an unknown impact via input data that sets crafted values for certain length variables, leading to a buffer overflow. | |||
| CVE-2025-68670 | 0.00 | — | 0.01 | Jan 27, 2026 | xrdp is an open source RDP server. xrdp before v0.10.5 contains an unauthenticated stack-based buffer overflow vulnerability.
