CVE-2026-73025
CriticalCVSS 9.8Exploitation Probability (EPSS)
Elevated risk58th percentile - higher than 58% of all known CVEs
Summary
Weak authentication in Windows iSCSI allows an unauthorized attacker to bypass a security feature over a network.
Risk Assessment
An attacker can bypass authentication and gain unauthorized access to iSCSI resources, potentially leading to data breach.
Recommendation
Update Windows and configure strong authentication mechanisms for iSCSI. Restrict access to iSCSI services on the network.
