CVE-2025-69274: Broadcom DX NetOps Privilege Escalation

CVE-2025-69274 Overview

CVE-2025-69274 is an Authorization Bypass Through User-Controlled Key vulnerability affecting Broadcom DX NetOps Spectrum on Windows and Linux platforms. This vulnerability allows authenticated attackers to potentially escalate privileges by manipulating user-controlled keys to bypass authorization controls. The flaw is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), which occurs when the system uses user-supplied input as a key to access resources without properly validating that the user is authorized to access the requested resource.

Critical Impact

Authenticated attackers can bypass authorization mechanisms to modify resources they should not have access to, potentially leading to privilege escalation within the DX NetOps Spectrum environment.

Affected Products

• Broadcom DX NetOps Spectrum version 24.3.10 and earlier (Windows)
• Broadcom DX NetOps Spectrum version 24.3.10 and earlier (Linux)

Technical Details for CVE-2025-69274

Vulnerability Analysis

This vulnerability stems from improper authorization controls in Broadcom DX NetOps Spectrum's handling of user-controlled keys. When a user provides input that is used as an identifier to access system resources, the application fails to properly validate whether the requesting user has legitimate authorization to access those resources. This creates an Insecure Direct Object Reference (IDOR) condition where attackers can manipulate key values to access or modify objects belonging to other users or gain elevated permissions.

The vulnerability requires authentication to exploit, meaning an attacker must first have valid credentials to the DX NetOps Spectrum system. Once authenticated, the attacker can manipulate request parameters containing user-controlled keys to bypass authorization checks and potentially escalate their privileges within the network management platform.

Root Cause

The root cause is the application's reliance on user-controlled input as a direct key for accessing protected resources without implementing proper authorization validation. This is a classic CWE-639 pattern where the application trusts that the key value provided by the user corresponds to resources they are authorized to access, rather than independently verifying authorization on the server side.

Attack Vector

The attack is network-based and requires the attacker to have low-privilege authenticated access to the DX NetOps Spectrum system. From there, the attacker can intercept and modify requests to change object identifiers or key values, potentially gaining access to resources or functionality reserved for higher-privileged users. The attack requires some prerequisite conditions to be present (AT:P in CVSS 4.0), indicating that exploitation may depend on specific configuration states or timing conditions.

The exploitation mechanism involves manipulating user-controlled identifiers in HTTP requests or API calls to reference resources the attacker should not be authorized to access. See the Broadcom Security Advisory for technical details.

Detection Methods for CVE-2025-69274

Indicators of Compromise

• Unusual access patterns where authenticated users access resources outside their normal authorization scope
• Anomalous parameter manipulation in HTTP requests or API calls to DX NetOps Spectrum
• Log entries showing users accessing configuration objects or resources they don't own
• Unexpected privilege elevation events for low-privilege user accounts

Detection Strategies

• Monitor DX NetOps Spectrum access logs for requests with manipulated object identifiers or key parameters
• Implement correlation rules to detect when users access resources inconsistent with their assigned roles
• Deploy web application firewall (WAF) rules to detect parameter tampering attacks against DX NetOps Spectrum endpoints
• Enable verbose audit logging on DX NetOps Spectrum to capture detailed access control events

Monitoring Recommendations

• Configure SIEM alerting for authorization failures followed by successful access to sensitive resources
• Monitor for unusual patterns of resource access that deviate from established user baselines
• Review DX NetOps Spectrum audit logs regularly for evidence of privilege escalation attempts
• Implement real-time monitoring for API request parameter anomalies

How to Mitigate CVE-2025-69274

Immediate Actions Required

• Review the Broadcom Security Advisory for official patch information
• Audit current user access and privileges within DX NetOps Spectrum deployments
• Implement network segmentation to limit access to DX NetOps Spectrum management interfaces
• Enable comprehensive audit logging to detect potential exploitation attempts

Patch Information

Broadcom has released a security advisory addressing this vulnerability. Organizations running DX NetOps Spectrum version 24.3.10 or earlier should consult the Broadcom Security Advisory for official remediation guidance and patch availability. Apply the latest security updates from Broadcom as soon as they become available for your deployment.

Workarounds

• Restrict network access to DX NetOps Spectrum management interfaces to trusted administrative networks only
• Implement additional authentication controls such as multi-factor authentication for DX NetOps Spectrum access
• Apply principle of least privilege by reviewing and minimizing user permissions within the platform
• Deploy application-layer monitoring to detect and block parameter manipulation attacks

# Example: Restrict network access to DX NetOps Spectrum management interface
# Add firewall rules to limit access to trusted admin networks only
iptables -A INPUT -p tcp --dport 443 -s 10.10.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
