Specifically, versions 9.2, 9.3, 9.4, 9.5, and 9.6 are susceptible to unauthenticated remote command execution. The vulnerability stems from insufficient validation of user-supplied input, allowing an attacker to inject and execute arbitrary commands on the system. Successful exploitation grants the attacker normal user privileges. This vulnerability poses a significant risk as it allows attackers to compromise the system without authentication, potentially leading to data breaches, system disruption, or further lateral movement within the network. Defenders should prioritize patching or mitigating this vulnerability.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies a vulnerable IBM Total Storage Service Console (TSSC) / TS4500 IMC instance running versions 9.2, 9.3, 9.4, 9.5, or 9.6.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious request containing an OS command injection payload.
