Commvault Web Server contains an unspecified vulnerability that allows a remote, authenticated attacker to create and execute webshells.

Commvault Command Center contains a path traversal vulnerability that allows a remote, unauthenticated attacker to execute arbitrary code.

During the brief window between installation and the first administrator login, remote attackers may exploit the default credential to gain admin control. This is limited to the setup phase, before any jobs have been configured.

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  The WebConsole package is currently end of life, and is no longer maintained.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 environment. However, if you choose to install it, for example, to access functionality like the Report Builder, it must be deployed within a fully isolated network that has no access to sensitive data or internet connectivity. This is a critical security precaution, as the retired package may contain unpatched vulnerabilities and is no longer supported with updates or fixes.

A local privilege escalation vulnerability exists in Commvault for Windows versions 11.20.0, 11.28.0, 11.32.0, 11.34.0, and 11.36.0. In affected configurations, a local attacker who owns a client system with the file server agent installed can compromise any assigned Windows access nodes. This may allow unauthorized access or lateral movement within the backup infrastructure. The issue has been resolved in versions 11.32.60, 11.34.34, and 11.36.8.

A DLL injection vulnerability exists in Commvault for Windows 11.20.0, 11.28.0, 11.32.0, 11.34.0, and 11.36.0. During the installation of maintenance updates, an attacker with local access may exploit uncontrolled search path or DLL loading behavior to execute arbitrary code with elevated privileges. The vulnerability has been resolved in versions 11.20.202, 11.28.124, 11.32.65, 11.34.37, and 11.36.15.

An SQL injection vulnerability exists in Commvault 11.32.0 - 11.32.93, 11.36.0 - 11.36.51, and 11.38.0 - 11.38.19 Web Server component that allows a remote, unauthenticated attacker to perform SQL Injection. The vulnerability impacts systems where the CommServe and Web Server roles are installed. Other Commvault components deployed in the same environment are not affected.

A security vulnerability has been identified that allows remote attackers to perform unauthorized file system access through a path traversal issue. The vulnerability may lead to remote code execution.

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.

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.
