The vulnerability stems from an insufficient UI warning mechanism when dangerous operations are about to be performed within an RDP session. An attacker could potentially exploit this to spoof legitimate actions or elements within the RDP interface, misleading the user into performing unintended actions. This vulnerability could be exploited by an attacker positioned on the same network as the victim, or through other means of network access. Successful exploitation could lead to information disclosure, unauthorized access, or other forms of compromise, depending on the specific actions spoofed. The vulnerability has a CVSS v3.1 score of 7.1, indicating a high severity.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains network access to a system that has an active RDP connection or will have an RDP connection in the future.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages their network position to intercept and manipulate RDP traffic.\u003c/li\u003e\n\u003cli\u003eThe attacker exploits CVE-2026-26151 to inject spoofed UI elements into the RDP session.\u003c/li\u003e\n\u003cli\u003eThe victim, unaware of the spoofed UI, interacts with the malicious elements.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the spoofed UI to trick the user into performing unintended actions, such as providing credentials or running malicious commands.\u003c/li\u003e\n\u003cli\u003eIf credentials were stolen the attacker authenticates using the stolen credentials.\u003c/li\u003e\n\u003cli\u003eThe attacker pivots to other systems on the internal network.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves their final objective, such as data exfiltration, deploying ransomware, or establishing persistent access.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-26151 could allow an attacker to perform spoofing attacks via manipulated UI elements within the Remote Desktop session.
