A security vulnerability has been identified that allows remote attackers to inject or manipulate command-line arguments passed to internal components due to insufficient input validation. Successful exploitation results in a valid user session for a low privilege role.

• → CVE-2025-57791 is chained with CVE-2025-57790 and CVE-2025-57788 in an unauthenticated RCE exploit chain; detect unauthenticated requests that result in session creation for the 'localadmin' account on Commvault HTTP endpoints. ↗
• → Monitor for exploitation of CVE-2025-57788 (hostname leak) as a precursor step to the full RCE chain involving CVE-2025-57791; the hostname leak is a required prerequisite. ↗
• → Exploitation results in code execution as 'NETWORK SERVICE' on Windows; alert on Commvault processes spawning child processes or network connections under the NETWORK SERVICE account. ↗
• → Successful exploitation of CVE-2025-57791 yields a valid low-privilege user session; monitor Commvault authentication logs for unexpected session creation, especially for low-privilege roles without prior credential activity. ↗
• → The attack vector is command-line argument injection into internal components; monitor Commvault service process command-line arguments for unexpected or injected parameters. ↗

• · CVE-2025-57791 is exploited as part of a multi-CVE chain (CVE-2025-57788, CVE-2025-57790, CVE-2025-57791); patching all three is required to break the full RCE chain. ↗
