Remote Desktop Client Code Execution Flaws
2026-06-09
Remote code execution in Microsoft Remote Desktop Client is possible when a victim connects to an attacker-controlled or compromised RDP server, triggering a heap-based buffer overflow that runs attacker code in the client's context. The flaw (CWE-416 use-after-free / heap corruption) carries CVSS 8.8 and requires user interaction, with no public exploit identified at time of analysis. A vendor patch is available via Microsoft MSRC.
Remote code execution in Microsoft Remote Desktop Client is possible when a victim connects to an attacker-controlled RDP server, where a heap-based buffer overflow (linked to use-after-free memory corruption per vendor tags) enables arbitrary code execution on the client machine. The CVSS 7.5 score reflects high attack complexity and required user interaction, and no public exploit identified at time of analysis. SSVC assessment from CISA rates exploitation as 'none' and automatable as 'no', though technical impact is total.
Remote code execution in Microsoft Remote Desktop Client is possible when a user connects to an attacker-controlled or compromised RDP endpoint, where a race condition (CWE-362) can be triggered to corrupt heap memory and execute arbitrary code in the client process. The flaw is unauthenticated from the network attacker's perspective but requires user interaction to initiate the connection, and no public exploit has been identified at time of analysis.
Remote code execution in Microsoft Remote Desktop Client is possible when a user connects to an attacker-controlled RDP server, where a heap-based buffer overflow triggered by a race condition (CWE-362) allows arbitrary code execution on the client machine. The flaw carries a CVSS 7.5 (High) rating with high attack complexity and required user interaction, and no public exploit identified at time of analysis. Microsoft has released a patch via MSRC advisory CVE-2026-42913.
Remote code execution in Microsoft Remote Desktop Client is possible when a user is lured into connecting to an attacker-controlled RDP server, where a heap-based buffer overflow (CWE-122) can be triggered to run arbitrary code on the client machine. The flaw was reported by Microsoft (secure@microsoft.com) and carries a CVSS 3.1 score of 7.5, reflecting high attack complexity and the requirement for user interaction. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Remote code execution in Microsoft Remote Desktop Client arises from a heap-based buffer overflow (CWE-122) that an unauthenticated network attacker can trigger when a victim connects to or interacts with a malicious server. Microsoft (secure@microsoft.com) is the originating reporter and has published an advisory in the MSRC update guide, with no public exploit identified at time of analysis. The CVSS 7.5 (High) rating reflects high attack complexity and required user interaction, but successful exploitation yields full confidentiality, integrity, and availability impact on the client host.
