Privilege escalation vulnerability in Windows Remote Access Connection Manager that allows an authenticated local attacker to elevate privileges to a higher integrity level without user interaction. The vulnerability affects Windows systems with Remote Access Connection Manager enabled and has a CVSS score of 7.8 (High severity). While no active exploitation in the wild has been publicly confirmed at this time, the local attack vector combined with low complexity and no user interaction requirement makes this a significant risk for multi-user or compromised systems where an attacker already has local access.

Privilege escalation vulnerability in Windows Installer that exploits improper symlink/junction handling (CWE-59: link following) to allow an authorized local attacker to elevate privileges without user interaction. With a CVSS score of 7.8 and CVSS vector indicating local attack vector with low complexity and no user interaction required, this vulnerability affects Windows Installer across multiple versions. Real-world risk depends on KEV/CISA status and EPSS probability, which should be cross-referenced against active exploitation reports and POC availability.

Windows SMB contains an improper access control vulnerability (CVE-2025-33073, CVSS 8.8) enabling authenticated attackers to escalate privileges over the network. KEV-listed with EPSS 57.6% and public PoC, this vulnerability in the core Windows file sharing protocol affects every Windows system on the network, enabling lateral movement from any compromised domain account to SYSTEM-level access on SMB-accessible systems.

Use-of-uninitialized-resource vulnerability in Windows Netlogon that allows unauthenticated network attackers to achieve privilege escalation through a complex exploitation path. The vulnerability affects Windows systems running Netlogon services and enables remote code execution with high impact on confidentiality, integrity, and availability. Given the network-based attack vector and lack of authentication requirements, this represents a significant threat to networked Windows environments, though exploitation requires specific conditions (high attack complexity).

Local privilege escalation vulnerability in the Windows Kernel stemming from improper privilege management (CWE-269), allowing an unauthenticated attacker with local system access to escalate privileges without user interaction. This affects multiple Windows versions and has a CVSS 8.4 severity rating indicating high confidentiality, integrity, and availability impact. The vulnerability's low attack complexity (AC:L) and lack of privilege requirements (PR:N) indicate it is relatively straightforward to exploit for any local attacker.

Heap-based buffer overflow vulnerability in Windows Routing and Remote Access Service (RRAS) that allows unauthenticated remote attackers to execute arbitrary code over the network with user interaction. This is a critical network-accessible vulnerability affecting Windows systems running RRAS; successful exploitation grants the attacker complete system compromise with high confidentiality, integrity, and availability impact. The CVSS 8.8 score reflects the severity, though real-world exploitation probability and active KEV status would determine if this is actively weaponized.

CVE-2025-32718 is an integer overflow vulnerability in Windows SMB that allows a locally authenticated attacker to achieve privilege escalation with high impact to confidentiality, integrity, and availability. The vulnerability affects Windows operating systems' SMB implementation and has a CVSS score of 7.8 (High) with low attack complexity, making it a significant local privilege escalation risk for multi-user systems and domain environments.

CVE-2025-32716 is an out-of-bounds read vulnerability in Windows Media that allows an authenticated local attacker to achieve privilege escalation on affected systems. The vulnerability has a CVSS score of 7.8 (high severity) due to its impact on confidentiality, integrity, and availability. Without confirmation of KEV status, active exploitation, or public POC availability from the provided data, the real-world risk assessment requires evaluation against the moderate attack complexity (local access required, authenticated user needed).
