Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a network.
AnalysisAI
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. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must initiate or accept an RDP connection from the Microsoft Remote Desktop Client to an attacker-controlled or attacker-influenced RDP server (UI:R), so a purely passive client on the network is not exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals point to a meaningful but not top-tier priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker stands up a malicious RDP server and lures a target - via phishing link, .rdp file attachment, watering-hole, or rogue Wi-Fi captive portal - to connect with the Windows Remote Desktop Client. During session negotiation or virtual-channel data exchange, the malicious server returns a crafted message that overflows a heap buffer in the client, achieving code execution in the user's context on the victim workstation. … |
| Remediation | Apply the Microsoft security update for CVE-2026-44799 as listed in the MSRC update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-44799; patch available per vendor advisory, but a specific fixed build is not included in the provided data and must be read from that advisory and the associated monthly cumulative update for each affected Windows release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Inventory all RDP deployments by criticality level, disable Remote Desktop on non-essential systems, and alert remote workers to avoid connecting to untrusted servers. …
