Commvault, a leading provider of data protection and management solutions, recently addressed a critical flaw in its webserver software that could potentially allow attackers to gain full control over systems running affected versions of Commvault’s software. This vulnerability poses a significant risk to organizations that rely on Commvault for their data backup and management needs.
The Webserver vulnerability, identified as CV_2025_03_1, revolves around Commvault’s webserver module, which cybercriminals could exploit to compromise systems. According to the official security advisory released by Commvault, attackers could create and execute webshells to gain unauthorized access to critical systems, potentially leading to severe data breaches and other cyberattacks. The flaw specifically affects Commvault software versions 11.20 through 11.36, making it crucial for users to apply the necessary patches to mitigate the risk.
The affected product versions include Commvault (Linux, Windows) versions 11.36.0 to 11.36.45 (resolved in 11.36.46), 11.32.0 to 11.32.87 (resolved in 11.32.88), 11.28.0 to 11.28.140 (resolved in 11.28.141), and 11.20.0 to 11.20.216 (resolved in 11.20.217). Commvault strongly urges organizations to install the updated versions on their CommServe and webservers promptly to address the flaw and enhance the security of their systems.
In a March 7th, 2025 update, Commvault confirmed that additional fixes had been implemented to further enhance the security of the webserver module. Timely application of these security patches is crucial for organizations using Commvault for backup and data management, as leaving the vulnerability unpatched could allow attackers to execute remote code, bypass security measures, and gain unauthorized access to sensitive data.
The recent vulnerability in Commvault’s webserver module underscores the risk of attackers potentially gaining full control over an organization’s systems, leading to severe consequences like data theft, unauthorized access to backups, and disruption of operations. Regular software updates and proactive vulnerability checks are essential to protect systems from exploitation, as cybercriminals continuously develop new methods to bypass security measures. By addressing identified vulnerabilities and maintaining cybersecurity practices, organizations can safeguard their critical data and infrastructure from the increasing threat of cybercrime.
