CVE-2025-24381 is an open redirect vulnerability classified under CWE-601 affecting Dell Unity storage management software versions 5.4 and earlier. The flaw allows an unauthenticated attacker with remote access to craft URLs that redirect legitimate users to arbitrary external websites. Since the redirection is untrusted, attackers can exploit this to conduct phishing campaigns by luring users to malicious sites designed to steal credentials or deliver malware. Additionally, session theft is possible if attackers capture session tokens via the redirected site, potentially leading to unauthorized access. The vulnerability requires user interaction to follow the malicious link but does not require any authentication or elevated privileges, making it easier to exploit remotely. The CVSS v3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to the widespread use of Dell Unity in enterprise storage environments. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to reduce exposure.

The vulnerability can lead to significant security breaches including credential theft, unauthorized access, and potential compromise of sensitive enterprise storage environments. Phishing attacks leveraging this open redirect can deceive users into divulging confidential information or downloading malware, impacting organizational confidentiality and integrity. Session theft can result in attackers hijacking user sessions, leading to further unauthorized actions within the affected system. Given Dell Unity's deployment in critical storage infrastructure worldwide, exploitation could disrupt business operations and data availability. The ease of exploitation without authentication and the potential for widespread phishing campaigns elevate the threat level, especially in sectors reliant on secure data storage such as finance, healthcare, and government. Organizations failing to address this vulnerability risk reputational damage, regulatory penalties, and operational downtime.

Organizations should immediately review and restrict URL redirection functionality within Dell Unity interfaces, implementing strict validation and allowlisting of redirect targets. Until official patches are released, consider deploying web application firewalls (WAFs) with rules to detect and block suspicious redirect patterns. Educate users about phishing risks and encourage verification of URLs before clicking links related to Dell Unity portals. Monitor network traffic for unusual redirection attempts and implement multi-factor authentication (MFA) to reduce session hijacking impact. Regularly audit and update endpoint security solutions to detect phishing payloads. Coordinate with Dell support for timely patch deployment once available and apply security best practices for storage management systems. Additionally, isolate Dell Unity management interfaces from public internet access where possible to limit exposure.
