rras vulnerability

About this tag
The rras vulnerability tag covers a series of critical remote code execution and elevation-of-privilege flaws in Microsoft's Routing and Remote Access Service (RRAS), a Windows component used for VPN termination, NAT, and routing. Recent discussions focus on out-of-band hotpatches like KB5084597, which provide restartless fixes for enterprise endpoints, and specific CVEs such as CVE-2026-25173, CVE-2026-25172, CVE-2026-20868, and CVE-2026-20843. These vulnerabilities often stem from integer overflows or wraparound issues and can be exploited remotely without authentication, making patching a priority for organizations running RRAS-based gateways. The tag includes technical analysis, mitigation guidance, and containment strategies for affected Windows systems.
