CVE-2026-44178 Details
Description
xrdp is an open source RDP server. Versions 0.10.6 and prior contain a heap-based buffer overflow vulnerability within the virtual channel forwarding mechanism. When forwarding data from a remote client to the internal channel server, the xrdp process utilizes a fixed-size buffer without adequate bounds checking on the incoming payload. An authenticated remote attacker can exploit this flaw by sending a specially crafted virtual channel message that exceeds the buffer capacity, leading to heap memory corruption. This may result in a denial of service or the execution of arbitrary code with the privileges of the xrdp process. This issue has been fixed in version 0.10.6.1.
A heap-based buffer overflow vulnerability has been identified in xrdp, an open-source RDP server, in versions through 0.10.6. The vulnerability arises within the virtual channel forwarding mechanism, where the xrdp process uses a fixed-size buffer to forward data from remote clients to the internal channel server. This buffer lacks proper bounds checking, allowing authenticated remote attackers to send specially crafted virtual channel messages that exceed the buffer capacity. Exploitation of this vulnerability leads to heap memory corruption, which could cause a denial of service or allow arbitrary code execution with the privileges of the xrdp process.
Users can upgrade to xrdp version 0.10.6.1 to address this vulnerability.
