Descriptions

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.
