A vulnerability in a known login mechanism allows unauthenticated attackers to execute API calls without requiring user credentials. RBAC helps limit the exposure but does not eliminate risk.

- →Detect unauthenticated GET requests to /commandcenter/publicLink.do — this is the first step of the exploit chain used to extract the GUID (cv-gorkha value) needed for the PublicSharingUser login.
- →Detect POST requests to /commandcenter/api/Login with the username '_+_PublicSharingUser_' — this is the unauthenticated login step using the base64-encoded GUID as the password.
- →Detect GET requests to /commandcenter/RestServlet/Database/GetUmUserById/1 with an Authtoken header — this is the credential-harvesting step that retrieves login, email, and password fields.
- →Alert on HTTP responses containing all of 'login', 'email', 'password', and 'datePasswordSet' from the /commandcenter/RestServlet/ path — this indicates successful credential disclosure.
- →CVE-2025-57788 is leveraged in the Metasploit RCE chain (CVE-2025-57790/57791) to leak the target hostname; correlate exploitation of this CVE with subsequent RCE attempts. ↗
- →Use the Shodan favicon hash -542502280 to identify exposed Commvault Command Center instances on the internet for proactive asset discovery.
- ·RBAC is a partial mitigation only — it limits exposure but does not prevent unauthenticated API access via the PublicSharingUser mechanism. ↗
- ·The vulnerability affects Commvault versions before 11.36.60; upgrade to 11.36.60 or later to remediate.
- ·The exploit chain requires exactly 3 sequential HTTP requests (publicLink.do → Login → GetUmUserById); detection logic should account for this multi-step flow.

CVE-2025-57790 [MEDIUM] Commvault Command-Line Argument Injection to Traversal Remote Code Execution
Commvault Command-Line Argument Injection to Traversal Remote Code Execution
This module exploits an unauthenticated remote code execution exploit chain for Commvault, tracked as CVE-2025-57790 and CVE-2025-57791. A command-line injection permits unauthenticated access to the 'localadmin' account, which then facilitates code execution via expression language injection. CVE-2025-57788 is also leveraged to leak the target host name, which is necessary knowledge to exploit the remote code execution chain. This module executes in the context of 'NETWORK SERVICE' on Windows.

Commvault vulnerability analysis and mitigation
The Report Builder component of the application stores user input directly in a web page and displays it to other users, which raised concerns about a possible Cross-Site Scripting (XSS) attack. Proper management of this functionality helps ensure a secure and seamless user experience. Although the user input is not validated in the report creation, these scripts are not executed when the report is run by end users. The script is executed when the report is modified through the report builder by a user with edit permissions.
The Report Builder is part of the WebConsole. The WebConsole package is currently end of life, and is no longer maintained. We strongly recommend against installing or using it in any production env
