CVE-2026-26360 is an External Control of File Name or Path vulnerability (CWE-73) affecting Dell Unisphere for PowerMax version 10.2. This flaw allows unauthorized manipulation of file paths, earning a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H), indicating high severity due to its potential for integrity and availability impacts over the network with low complexity and low privileges required.

A low-privileged attacker with remote access can exploit this vulnerability to delete arbitrary files on the affected system. The attack requires no user interaction and maintains an unchanged scope, enabling disruption of critical storage management operations in PowerMax environments without compromising confidentiality.

Dell's security advisory DSA-2026-102, detailed at https://www.dell.com/support/kbdoc/en-us/000429268/dsa-2026-102-dell-unisphere-for-powermax-and-powermax-eem-security-update-for-multiple-vulnerabilities, addresses this and other vulnerabilities in Unisphere for PowerMax and PowerMax EEM with a security update. Practitioners should apply the patch to mitigate exploitation risks.

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
