Executive Summary

CVE-2026-5935 is an OS Command Injection vulnerability affecting IBM's Total Storage Service Console (TSSC) and TS4500 Integrated Management Console (IMC) versions 9.2 through 9.6.

It allows an unauthenticated attacker to execute arbitrary operating system commands with normal user privileges on the affected system.

This happens because the software improperly validates user-supplied input via an HTTP/HTTPS endpoint.

Detection Guidance

The CVE-2026-5935 vulnerability is an OS Command Injection issue exploitable via an HTTP/HTTPS endpoint on IBM Total Storage Service Console (TSSC) and TS4500 Integrated Management Console (IMC) versions 9.2 through 9.6.

Detection typically involves monitoring for suspicious HTTP/HTTPS requests that attempt to inject OS commands through user-supplied input parameters. However, no specific detection commands or signatures are provided in the available information.

Since the vulnerability allows unauthenticated command execution, network monitoring tools could be used to inspect incoming HTTP/HTTPS traffic for unusual or malformed requests targeting the TSSC/IMC management interfaces.

IBM recommends applying patches or upgrading to fixed versions to remediate the vulnerability, as no workarounds or mitigations are available.

Because no explicit detection commands or scripts are provided, it is advised to check the version of your TSSC/IMC installations and verify if they are at or above the fixed versions (9.4.31, 9.6.15, or patched versions).
