AnalysisAI

Information disclosure in xrdp (neutrinolabs open-source RDP server) before version 0.10.6.1 stems from an integer overflow (CWE-190) reachable over the network without authentication, allowing remote attackers to leak sensitive memory contents and crash the service. The flaw was reported via Ubuntu and fixed in the v0.10.6.1 release, which bundled remediation for ten separate CVEs. There is no public exploit identified at time of analysis, and the EPSS score is modest (0.59%, 44th percentile), indicating no confirmed active exploitation.

Technical ContextAI

xrdp is a widely-used open-source implementation of Microsoft's Remote Desktop Protocol (RDP) that lets clients establish graphical remote sessions to Linux/Unix hosts on TCP port 3389. The affected component is the neutrinolabs xrdp package (CPE cpe:2.3:a:neutrinolabs:xrdp) at all versions prior to 0.10.6.1. The root cause is CWE-190 (Integer Overflow or Wraparound): an arithmetic operation - almost certainly on an attacker-influenced length or size field parsed from the RDP protocol stream - wraps around, producing an undersized allocation or a miscomputed bounds check. This class of bug typically leads to out-of-bounds reads (exposing adjacent heap/stack memory, consistent with the Information Disclosure tag and CVSS C:H) and to memory-corruption-driven crashes (consistent with A:H). The fix is part of the GHSA-v8w6-pf78-9458 security advisory.

RemediationAI

Vendor-released patch: 0.10.6.1 - upgrade xrdp to version 0.10.6.1 or later, which fixes this issue (GHSA-v8w6-pf78-9458) along with nine other CVEs and a TLS regression; obtain it from https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.6.1 or via your Linux distribution's updated package (Ubuntu users should apply the distro security update since Ubuntu reported the flaw). If you cannot patch immediately, reduce exposure by restricting network reachability of TCP port 3389: firewall xrdp so it is only reachable from trusted management networks or over a VPN rather than the public internet, which cuts off unauthenticated remote attackers at the cost of requiring VPN/jump-host access for legitimate users. Where remote graphical access is not actively needed, stop and disable the xrdp service entirely. These are compensating controls only - because the overflow is triggered during protocol parsing before authentication, access restriction is the reliable mitigation until the upgrade is applied.
