CVE ID Description CWE ID
CVE-2025-59230 Microsoft Windows contains an improper access control vulnerability in Windows Remote Access Connection Manager which could allow an authorized attacker to elevate privileges locally. CWE-284
CISA added this vulnerability to its Known Exploited Vulnerabilities catalog on Sat, Oct 14, 2025, and has set a deadline of Sat, Nov 4, 2025, for remediation.
The vulnerability is located in the Windows Remote Access Connection Manager component, which manages remote network connections.
Exploitation of this vulnerability can lead to unauthorized privilege escalation, allowing attackers to execute malicious activities such as installing malware, stealing data, or disrupting network services. This poses a significant risk, especially in environments with remote work setups.
To mitigate this threat, CISA advises applying all mitigations provided by Microsoft promptly. If a patch is available, it should be tested and deployed according to standard procedures. In the absence of a patch, administrators are advised to disable or isolate the vulnerable service following vendor guidance.
Review internal monitoring and logging practices to detect unusual privilege escalation attempts. Conduct regular vulnerability scans and ensure prompt patch management. Prioritize addressing this vulnerability along with other critical updates.
Failure to address this issue by the deadline could result in more sophisticated exploits or facilitate lateral movement within networks. CISA and Microsoft will continue monitoring the situation and provide further updates as necessary.
