Authentication Bypass Vulnerability in Commvault Products

CVE-2025-57788

What is CVE-2025-57788?

CVE-2025-57788 is a significant vulnerability found in Commvault products, which are designed for data management, backup, and recovery. This vulnerability arises from a flaw in the authentication mechanism that allows unauthenticated attackers to make API calls without the need for valid user credentials. Although role-based access control (RBAC) mechanisms are in place to help restrict unauthorized access, they do not completely eliminate the risks associated with this vulnerability. If exploited, it could lead to unauthorized access and manipulation of sensitive data, potentially jeopardizing the security posture of organizations that rely on these Commvault systems.

Potential impact of CVE-2025-57788

1. Unauthorized Data Access: The vulnerability enables attackers to bypass necessary authentication checks, allowing them to access sensitive data without proper authorization. This could lead to data breaches and exposure of confidential information.

2. API Misuse: Since attackers can execute API calls without credentials, they could exploit this capability to perform unauthorized actions on the Commvault environment, potentially compromising data integrity and availability.

3. Increased Attack Surface: The existence of this vulnerability enhances the attack surface available to malicious actors, making it easier for them to launch further attacks, gain a foothold within organizational systems, or prepare for more complex exploitations in weaponized environments.
