CVE-2025-46424

6.7 MEDIUM

📋 TL;DR

Dell CloudLink versions before 8.2 contain a cryptographic implementation vulnerability that allows high-privileged attackers to cause denial of service. This affects organizations using Dell CloudLink for cloud management and orchestration. Attackers with administrative access could disrupt service availability.

💻 Affected Systems

Products:
  • Dell CloudLink
Versions: All versions prior to 8.2
Operating Systems: Not OS-specific - affects CloudLink software itself
Default Config Vulnerable: ⚠️ Yes
Notes: Requires high-privileged attacker access. CloudLink deployments managing cloud infrastructure are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete service disruption of Dell CloudLink management platform, potentially affecting cloud orchestration and management capabilities for extended periods.

🟠

Likely Case

Temporary service interruption or performance degradation of CloudLink management functions until system restart or recovery procedures.

🟢

If Mitigated

Minimal impact with proper access controls and monitoring, though cryptographic weaknesses remain present.

🌐 Internet-Facing: MEDIUM - While exploitation requires high privileges, internet-facing instances could be targeted if credentials are compromised.
🏢 Internal Only: HIGH - Internal administrators or compromised high-privilege accounts could exploit this to disrupt critical cloud management services.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires high-privileged access and understanding of the cryptographic implementation weakness. No public exploits known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 8.2 or later

Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000384363/dsa-2025-374-security-update-for-dell-cloudlink-multiple-security-vulnerabilities

Restart Required: Yes

Instructions:

1. Download Dell CloudLink version 8.2 or later from Dell support portal. 2. Backup current configuration. 3. Install the update following Dell's upgrade documentation. 4. Restart CloudLink services. 5. Verify functionality post-update.

🔧 Temporary Workarounds

Restrict Administrative Access

all

Limit high-privilege accounts to only essential personnel and implement multi-factor authentication.

Network Segmentation

all

Isolate CloudLink management interfaces from general network access.

🧯 If You Can't Patch

  • Implement strict access controls and monitoring for all administrative accounts
  • Deploy network segmentation to limit CloudLink management interface exposure

🔍 How to Verify

Check if Vulnerable:

Check CloudLink version via web interface or CLI. Versions below 8.2 are vulnerable.

Check Version:

cloudlink --version or check web admin interface version information

Verify Fix Applied:

Confirm version is 8.2 or higher and verify cryptographic functions are operating normally.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected service restarts
  • Authentication failures for admin accounts
  • Cryptographic operation errors

Network Indicators:

  • Unusual traffic patterns to CloudLink management interfaces
  • Multiple failed authentication attempts

SIEM Query:

source="cloudlink" AND (event_type="service_restart" OR auth_failure="true")
