West Houston, TX – April 24, 2025 — A critical vulnerability has been discovered in the popular Commvault Command Center software, allowing attackers to execute code remotely without authentication.

The flaw, tracked as CVE-2025-34028, has a CVSS severity score of 9.0 out of 10, making it one of the most serious security risks in recent months. Impress IT Solutions in West Houston is proactively helping local businesses identify, patch, and secure their environments against this dangerous threat.

“Backup and replication platforms like Commvault are essential for business continuity—but when vulnerabilities strike, they can become the Achilles’ heel,” said the cybersecurity team at Impress IT Solutions. “That’s why fast action is critical.”

 

What Is the Commvault Command Center Vulnerability?

The flaw affects Commvault’s 11.38 Innovation Release, specifically versions 11.38.0 through 11.38.19. It has been addressed in:

  • 11.38.20
  • 11.38.25

According to researchers, the problem is rooted in the deployWebpackage.do endpoint, which fails to properly filter which hosts the server can communicate with. This opens the door for:

  • Server-Side Request Forgery (SSRF)
  • Pre-authenticated remote code execution
  • Full system compromise

An attacker could trick the Commvault server into:

  1. Downloading a malicious ZIP file from an external server.
  2. Extracting the ZIP contents into a temporary directory.
  3. Traversing directories to place a malicious web shell (shell.jsp) into a live server directory.
  4. Executing the malicious code remotely without needing any credentials.

Why It Matters to West Houston Businesses

Commvault is widely used across industries—including manufacturing, legal, finance, and healthcare—to back up and recover critical business data.

If compromised, attackers could:

  • Steal backups and sensitive client information
  • Encrypt or destroy data to demand a ransom
  • Use the backup server as a launchpad to attack the broader network

“Backup platforms are high-value targets for ransomware groups and nation-state attackers,” said Impress IT’s cybersecurity team. “If they control your backups, they control your recovery options.”
