CVE-2026-44178: CWE-122: Heap-based Buffer Overflow in neutrinolabs xrdp
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.
AI Analysis
Technical Summary
The vulnerability in neutrinolabs xrdp (CVE-2026-44178) is a heap-based buffer overflow occurring in the virtual channel forwarding component. The xrdp process uses a fixed-size buffer without proper bounds checking on incoming payloads forwarded from remote clients to the internal channel server. An authenticated attacker can exploit this by sending an oversized virtual channel message, resulting in heap memory corruption. This may allow denial of service or arbitrary code execution under the xrdp process privileges. The flaw affects versions up to and including 0.10.6 and has been fixed in version 0.10.6.1.
Potential Impact
Successful exploitation can lead to denial of service or arbitrary code execution with the privileges of the xrdp process. This elevates the risk of system compromise or service disruption on affected systems running vulnerable versions.
Mitigation Recommendations
Upgrade xrdp to version 0.10.6.1 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the vendor advisory, but the fix version is stated.
