Multiple Dell Unity Vulnerabilities Allow Attackers to Compromise Systems

Dell Technologies has released a security advisory detailing multiple critical vulnerabilities in its Dell Unity storage systems and related software.

These vulnerabilities, if exploited, could allow attackers to gain unauthorized access, execute arbitrary commands, or even compromise the affected systems entirely.

Vulnerabilities Explained

The advisory, issued under reference DSA-2025-116, highlights serious weaknesses in Dell Unity, UnityVSA, and Unity XT platforms, including their operating environment (OE).

These vulnerabilities affect versions before 5.5.0.0.5.259 and stem from several issues such as improper neutralization of special elements in system commands, open redirect flaws, and OS command injection vulnerabilities.

Key CVEs Identified

• CVE-2025-22398: This critical vulnerability allows unauthenticated attackers to execute arbitrary OS commands remotely. Exploitation could lead to complete control over the system with root privileges.
• CVE-2025-24383: Similar to CVE-2025-22398, this allows attackers to delete critical system files remotely.
• CVE-2025-24381: An open redirect vulnerability could enable attackers to redirect users to malicious sites, potentially leading to phishing attacks or session hijacking.
• CVE-2024-49563 to CVE-2025-24386: Several local privilege-escalation flaws were reported, enabling attackers with limited access to execute commands with root privileges.

Dell has acknowledged the contributions of security researchers, including teams from Ubisectech Sirius, who reported many of these vulnerabilities.

Impact on Users

The vulnerabilities have been classified as critical, with high CVSS scores ranging from 7.3 to 9.8. Exploitation risks include:

• Complete system compromise.
• Arbitrary file deletion, which could disrupt critical functions.
• Potential for phishing attacks.
• Local and remote elevation of privileges.

Given the severity, these flaws pose a significant risk to enterprises relying on Dell Unity systems for their storage solutions.

Mitigation and Updates

Dell has released version 5.5.0.0.5.259 of the Unity Operating Environment (OE) to address these vulnerabilities. Customers are strongly advised to upgrade immediately to mitigate risks.

1. Confirm whether your Unity systems are running a version prior to 5.5.0.0.5.259.
2. Download and apply the updated software via Dell Support (link).
3. Follow Dell’s best practices to secure your systems and minimize potential exploits.

Organizations using Dell Unity solutions should prioritize this patch to secure their infrastructures and prevent potential attacks.

Dell credited independent researchers, including Prowser and the Ubisectech Sirius Team, for their contributions in identifying these vulnerabilities.

The company recommends that customers assess the applicability of these findings to their environments and take swift action.

Dell has reiterated its commitment to strengthening security in its products through collaboration with the cybersecurity community.
