Overview
CVE-2025-57790 is a significant security vulnerability discovered in versions of Commvault before 11.36.60. This vulnerability allows remote attackers to perform unauthorized file system access through a path traversal issue, potentially leading to remote code execution. This security flaw has a wide-reaching impact, affecting all users running susceptible versions of Commvault. It is of paramount concern due to the severity of potential system compromises and data leakage.

How the Exploit Works
The exploit takes advantage of a path traversal issue in Commvault. The attacker submits a crafted request to the vulnerable system, which includes a malformed file path. This corrupted path allows the attacker to navigate outside of the intended directory structure, gaining access to files or directories that should be off-limits. The result is unauthorized file system access which could lead to remote code execution.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited, using a simple HTTP request:
GET /vulnerable/endpoint?file=../../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, the attacker requests a file located outside of the intended directory structure (`../../../etc/passwd`). If the system is vulnerable to the path traversal issue described by CVE-2025-57790, the request would succeed, allowing the attacker to read sensitive files.
Mitigation and Recommendations
Users of affected Commvault versions are strongly advised to update their systems to version 11.36.60 or later, where the issue has been rectified. As a temporary mitigation method, users can also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS), configured to detect and block path traversal attempts.
However, these measures are only temporary and are not foolproof. The most effective way to protect against this vulnerability is by applying the vendor patch. It is also recommended to always keep your systems up-to-date and routinely check for any security updates or patches.
