CVE-2026-50426: CWE-23: Relative Path Traversal in Microsoft Windows 10 Version 1607
Relative path traversal in DNS Server allows an authorized attacker to execute code over an adjacent network.
AI Analysis
Technical Summary
This vulnerability involves relative path traversal in the DNS Server on Windows 10 Version 1607 (build 10.0.14393.0). An attacker with authorized access and high privileges can exploit this flaw to execute arbitrary code remotely over an adjacent network. The CVSS vector indicates low attack complexity, no user interaction required, and high impact on confidentiality, integrity, and availability. Microsoft has published an official fix addressing this issue.
Potential Impact
Exploitation of this vulnerability could allow an authorized attacker with high privileges to execute arbitrary code remotely on the affected system, potentially leading to full compromise of confidentiality, integrity, and availability of the system. However, exploitation requires adjacent network access and high privileges, limiting the attack surface.
Mitigation Recommendations
An official fix is available from Microsoft. Users and administrators should apply the security update provided in the Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50426 to remediate this vulnerability.
