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  The WebConsole package is currently end of life, and is no longer maintained.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

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.

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.

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.

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.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Commvault CommCell 11.22.22. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the AppStudioUploadHandler class. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-13894.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Commvault CommCell 11.22.22. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the DemoExecuteProcessOnGroup workflow. By creating a workflow, an attacker can specify an arbitrary command to be executed. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-13889.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Commvault CommCell 11.22.22. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the DownloadCenterUploadHandler class. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-13756.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Commvault CommCell 11.22.22. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the DataProvider class. The issue results from the lack of proper validation of a user-supplied string before executing it as JavaScript code. An attacker can leverage this vulnerability to escape the JavaScript sandbox and execute Java code in the context of NETWORK SERVICE. Was ZDI-CAN-13755.

This vulnerability allows remote attackers to bypass authentication on affected installations of Commvault CommCell 11.22.22. Authentication is not required to exploit this vulnerability. The specific flaw exists within the CVSearchService service. The issue results from the lack of proper validation prior to authentication. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-13706.

In CommCell in Commvault before 14.68, 15.x before 15.58, 16.x before 16.44, 17.x before 17.29, and 18.x before 18.13, Directory Traversal can occur such that an attempt to view a log file can instead view a file outside of the log-files folder.

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.

Commvault Edge Communication Service (cvd) prior to version 11 SP7 or version 11 SP6 with hotfix 590 is prone to a stack-based buffer overflow vulnerability that could lead to arbitrary code execution with administrative privileges.

The Web Console in Commvault Edge Server 10 R2 allows remote attackers to execute arbitrary OS commands via crafted serialized data in a cookie.
