CVE-2026-20868: CWE-122: Heap-based Buffer Overflow in Microsoft Windows 10 Version 1607
Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.
AI Analysis
Technical Summary
This vulnerability involves a heap-based buffer overflow in the Windows RRAS component on Windows 10 Version 1607 (build 10.0.14393.0). Exploitation could allow an unauthenticated attacker to execute arbitrary code remotely, impacting confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. Microsoft has published a patch to remediate this vulnerability.
Potential Impact
Successful exploitation can lead to remote code execution by an unauthorized attacker, resulting in full compromise of the affected system's confidentiality, integrity, and availability. This could allow attackers to run arbitrary code with system privileges over the network.
Mitigation Recommendations
A patch is available for this vulnerability. It is recommended to apply the official Microsoft update for Windows 10 Version 1607 to remediate this issue. No additional mitigation steps are indicated beyond applying the patch.
