"The version of AIX installed on the remote host is prior to APAR IJ55897. It is, therefore, affected by multiple
vulnerabilities as referenced in the IJ55897 advisory.

  - IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 nimsh service SSL/TLS implementations could allow a remote
    attacker to execute arbitrary commands due to improper process controls. This addresses additional attack
    vectors for a vulnerability that was previously addressed in CVE-2024-56347. (CVE-2025-36251)

  - IBM AIX 7.2 and 7.3 nimsh service SSL/TLS protection mechanisms could allow a remote attacker to execute
    arbitrary commands due to improper process controls. (CVE-2024-56347)

  - IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 stores NIM private keys used in NIM environments in an
    insecure way which is susceptible to unauthorized access by an attacker using man in the middle
    techniques. (CVE-2025-36096)

  - IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 NIM server (formerly known as NIM master) service (nimesis)
    could allow a remote attacker to execute arbitrary commands due to improper process controls. This
    addresses additional attack vectors for a vulnerability that was previously addressed in CVE-2024-56346.
