Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-24381 is an URL Redirection to Untrusted Site ('Open Redirect') vulnerability, classified as CWE-601, affecting Dell Unity versions 5.4 and prior. Published on 2025-03-28, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low attack complexity, no required privileges, user interaction dependency, and high impacts on confidentiality, integrity, and availability.

An unauthenticated attacker with remote access can exploit this vulnerability to redirect targeted application users to arbitrary web URLs. This enables phishing attacks that trick users into divulging sensitive information, and exploitation may also facilitate session theft.

Dell's DSA-2025-116 advisory provides a security update addressing multiple vulnerabilities in Dell Unity, Dell UnityVSA, and Dell Unity XT, including CVE-2025-24381.

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly checks and rejects untrusted redirect targets before they are used in a response.

Information flow enforcement can restrict redirects to only approved/trusted destinations, stopping untrusted user-supplied URLs from being followed.
