Vulnerability AssessmentAI

Risk Assessment	This vulnerability presents minimal real-world risk despite being publicly disclosed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated local user with limited privileges (non-administrator) on a system running Iperius Backup 8.7.3 manipulates the NTLM2 authentication handler—potentially through crafted backup job configurations or direct interaction with backup processes—to trigger credential exposure or NTLM relay scenarios. By exploiting the high-complexity attack path, the attacker extracts cached or in-transit NTLM credentials or session tokens, gaining visibility into backup authentication material. …
Remediation	Immediately upgrade Enter Software Iperius Backup to version 8.7.4 or later, which contains the vendor's fix for the NTLM2 Handler information disclosure flaw. … Detailed patch versions, workarounds, and compensating controls in full report.
