CVE-2025-57789 Scanner

Commvault is a popular data protection and information management solution used worldwide by enterprises to manage data growth effectively. It is extensively used by IT professionals and organizations to ensure data backup, recovery, and management. The software is leveraged in various industries, including financial services, healthcare, and telecommunications, for safeguarding critical data assets. With its robust capabilities, Commvault assists organizations in meeting compliance requirements and enhancing data security. It provides features such as data deduplication, encryption, and cloud integration, delivering comprehensive data management services. Commvault also facilitates disaster recovery and business continuity processes through its advanced functionalities.

The Default Credentials vulnerability in Commvault pertains to a security flaw that occurs during the setup phase of the software. Before version 11.36.60, Commvault was found to be vulnerable to exploitation due to the use of a default credential during the installation process. This vulnerability poses a risk as it allows remote attackers to gain administrative control over the system before any security configurations are applied. It is critical to address this flaw to prevent unauthorized access and potential data breaches. In essence, this vulnerability highlights the importance of securing default credentials to protect against unauthorized exploitation.

In technical terms, the vulnerability occurs during the brief window between installation and the first administrator login. Remote attackers can exploit the default credential used by Commvault, primarily affecting the command center's public access link. The attack vector involves using HTTP request methods to interact with the 'commandcenter/publicLink.do' endpoint. Successful exploitation can result in obtaining sensitive tokens and administrative privileges. Mitigation requires immediate alteration of default credentials post-installation to secure the system against unauthorized access.

If exploited, this vulnerability can lead to severe consequences such as unauthorized administrative access, potentially compromising the entire data management infrastructure. Attackers could execute arbitrary commands, modify or delete critical data, and disrupt data management operations. Further, unauthorized access could facilitate espionage and data theft, affecting the organization's confidentiality and integrity. Therefore, it is crucial to address this vulnerability promptly to safeguard against potential exploitation and its detrimental effects.
