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  The WebConsole package is currently end of life, and is no longer maintained.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 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.

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.

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.

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.

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.

A Command Injection issue was discovered in ContentStore/Base/CVDataPipe.dll in Commvault before v11 SP6. A certain message parsing function inside the Commvault service does not properly validate the input of an incoming string before passing it to CreateProcess. As a result, a specially crafted message can inject commands that will be executed on the target operating system. Exploitation of this vulnerability does not require authentication and can lead to SYSTEM level privilege on any system running the cvd daemon. This is a different vulnerability than CVE-2017-3195.
