CVE-2025-57788 Scanner

The Commvault software is widely used by enterprises for data protection and information management across various IT infrastructures. Organizations utilize Commvault to backup, recover, and manage data in cloud, virtual, and physical environments. It provides solutions for data availability and accessibility, ensuring that IT professionals can securely handle enterprise data. The vulnerability identified in this software allows attackers to exploit the API endpoint, which is crucial for the software's integration and automation within enterprise systems. This makes it a significant concern for businesses relying on Commvault's API functionality. Such vulnerabilities can affect user trust and enterprise operations if not mitigated promptly.

The Unauthorized API Access vulnerability in Commvault allows unauthenticated attackers to make API calls without user credentials. This can enable unauthorized access to sensitive information or alter configurations that should be protected by authentication layers. The issue arises from a flaw in the login mechanism that does not fully verify credentials before granting access. Even though Role-Based Access Control (RBAC) limits some exposure, it cannot entirely prevent unauthorized API interactions. Therefore, the vulnerability can lead to severe security breaches if exploited by attackers. Awareness and timely updates are essential to mitigate the risk posed by this flaw.

In technical terms, the vulnerability is triggered when an attacker makes a crafted request to the Commvault API endpoint. Specifically, the endpoint '/commandcenter/RestServlet/Test/Echo/{{random}}' is susceptible, allowing arbitrary calls when processed without adequate authentication checks. The attack vector involves sending a request to this endpoint using a crafted HTTP GET request, which the server processes and responds with a '200 OK' status along with the expected random echo message in the response body. This condition signifies the success of the unauthorized access, per the vulnerability's exploitation requirements. The API response confirms the vulnerability when the server includes the crafted random text within the 'Message:' in the body, meaning the system processed the unauthorized request as legitimate.

If exploited, the Unauthorized API Access vulnerability in Commvault can lead to potential exposure of sensitive data and system configurations. Malicious individuals could execute arbitrary operations or retrieve protected information without valid credentials. This breach can escalate to larger attacks if attackers use the first access to establish further control or explore additional vulnerabilities. It poses reputational and operational risks as data integrity could be compromised, leading to potential data losses or unauthorized disclosures. Organizations using Commvault could face compliance issues, potential financial losses, and damage to consumer trust resulting from such security incidents.
