CVE-2024-22318

Status: ModifiedMedium (5.5)—

IBM i Access Client Solutions (ACS) 1.1.2 through 1.1.4 and 1.1.4.3 through 1.1.9.4 is vulnerable to NT LAN Manager (NTLM) hash disclosure by an attacker modifying UNC capable paths within ACS configuration files to point to a hostile server. If NTLM is enabled, the Windows operating system will try to authenticate using the current user's session. The hostile server could capture the NTLM hash information to obtain the user's credentials. IBM X-Force ID: 279091.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
