IBM i Access Client Solutions (ACS) is vulnerable to downloading unverified product code when configured to update from an IBM i.  A bad actor could use this vulnerablity to run compromised code on the ACS user's workstation.

IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 is vulnerable to zip slip path traversal exploit when importing a configuration.

IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 could allow a local attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.

IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 is vulnerable to arbitrary code execution on Windows when installed for all users due to publicly writeable configuration file.

IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 is vulnerable to arbitrary code execution on Windows when installed for all users due to publicly writeable directory.

IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 is vulnerable to injection of rogue certificate authority due to publicly writeable truststore.

IBM i Access Family 1.1.2 through 1.1.4 and 1.1.4.3 through 1.1.9.0 could allow a local authenticated attacker to execute arbitrary code on the system, caused by DLL search order hijacking vulnerability. By placing a specially crafted file in a compromised folder, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 236581.

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.
