CVE-2025-69276
📋 TL;DR
A deserialization vulnerability in Broadcom DX NetOps Spectrum allows attackers to inject malicious objects by sending untrusted data to the application. This affects all DX NetOps Spectrum installations on Windows and Linux running version 24.3.13 or earlier. Successful exploitation could lead to remote code execution or system compromise.
💻 Affected Systems
- Broadcom DX NetOps Spectrum
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with SYSTEM/root privileges leading to complete system takeover, data exfiltration, and lateral movement across the network.
Likely Case
Remote code execution with application service account privileges, allowing attackers to install malware, steal credentials, and pivot to other systems.
If Mitigated
Limited impact due to network segmentation and strict access controls, potentially resulting in denial of service or limited data exposure.
🎯 Exploit Status
Deserialization vulnerabilities typically have reliable exploitation paths once understood. The CVSS score of 8.8 suggests exploitation is feasible with moderate attacker skill.
