Summary

CVE-2025-57790 is a high-severity Absolute Path Traversal (CWE-36) vulnerability in Commvault Commvault. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly prevents path traversal attacks by validating and sanitizing file path inputs to block unauthorized file system access.

SI-2 Flaw Remediation good match

prevent

Ensures timely identification, reporting, and patching of the specific path traversal vulnerability as detailed in the Commvault advisory.

AC-3 Access Enforcement partial match

prevent

Enforces logical access controls to restrict low-privilege users from unauthorized file system access despite path traversal attempts.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Path traversal in a remotely accessible Commvault component directly enables T1190 (Exploit Public-Facing Application) with subsequent high-impact file-system access and RCE potential.

NVD Description

A security vulnerability has been identified that allows remote attackers to perform unauthorized file system access through a path traversal issue. The vulnerability may lead to remote code execution.

Deeper analysisAI

CVE-2025-57790 is a path traversal vulnerability (CWE-36) in Commvault software that enables remote attackers to perform unauthorized file system access. This issue, published on 2025-08-20, carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential to escalate to remote code execution.

Attackers with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low complexity and no user interaction required. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing unauthorized file system traversal and potential remote code execution on affected systems.

The Commvault security advisory at https://documentation.commvault.com/securityadvisories/CV_2025_08_2.html provides details on mitigation and patches for this vulnerability.
