CVE-2026-33516: CWE-125: Out-of-bounds Read in neutrinolabs xrdp
CVE-2026-33516 is an out-of-bounds read vulnerability in neutrinolabs xrdp versions prior to 0. 10. 6. It occurs during the RDP capability exchange phase when memory is accessed without validating the remaining buffer length. A remote, unauthenticated attacker can exploit this by sending a specially crafted Confirm Active PDU. Exploitation may cause a denial of service via process crash or potentially disclose sensitive process memory information. The issue is fixed in version 0. 10. 6.
AI Analysis
Technical Summary
The vulnerability CVE-2026-33516 affects neutrinolabs xrdp, an open source RDP server, in versions before 0.10.6. It is an out-of-bounds read (CWE-125) triggered during the RDP capability exchange phase due to insufficient validation of buffer length before memory access. An unauthenticated remote attacker can send a crafted Confirm Active PDU to trigger this flaw. Successful exploitation can lead to denial of service or information disclosure from process memory. The vendor fixed this vulnerability in xrdp version 0.10.6.
Potential Impact
Exploitation of this vulnerability can cause the xrdp server process to crash, resulting in denial of service. Additionally, it may allow an attacker to read sensitive information from the process memory, potentially leading to information disclosure. The vulnerability is remotely exploitable without authentication.
Mitigation Recommendations
Upgrade neutrinolabs xrdp to version 0.10.6 or later where this vulnerability is fixed. Since this is not a cloud service, patching the affected software version is required to remediate the issue. Patch status is confirmed by the vendor fix in version 0.10.6.
