CVE-2026-5935 affects IBM Total Storage Service Console (TSSC) and TS4500 IMC in versions 9.2, 9.3, 9.4, 9.5, and 9.6. The vulnerability arises from improper validation of user-supplied input, enabling an unauthenticated user to execute arbitrary commands with normal user privileges on the system. Classified as CWE-78 (OS Command Injection), it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) and was published on 2026-04-23.

An unauthenticated attacker with network access can exploit this issue with low complexity and no user interaction required. Exploitation allows execution of arbitrary commands under normal user privileges, resulting in low impacts to confidentiality, integrity, and availability.

IBM has published an advisory at https://www.ibm.com/support/pages/node/7270127 detailing the vulnerability and associated mitigations or patches.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
