CVE-2025-69267: Broadcom DX NetOps Path Traversal Flaw

CVE-2025-69267 Overview

CVE-2025-69267 is a Path Traversal vulnerability affecting Broadcom DX NetOps Spectrum on Windows and Linux platforms. This vulnerability arises from improper limitation of a pathname to a restricted directory, allowing attackers to traverse file system paths and potentially access files outside the intended directory structure.

Critical Impact

Authenticated attackers can exploit this path traversal flaw to access sensitive files and potentially compromise system confidentiality and integrity across both Windows and Linux deployments of DX NetOps Spectrum.

Affected Products

• Broadcom DX NetOps Spectrum version 24.3.8 and earlier (Windows)
• Broadcom DX NetOps Spectrum version 24.3.8 and earlier (Linux)

Technical Details for CVE-2025-69267

Vulnerability Analysis

This path traversal vulnerability (CWE-22) allows an attacker with low privileges to manipulate file path inputs and escape the intended directory boundaries. The vulnerability requires network access and authentication but does not require user interaction, making it exploitable in automated attack scenarios.

The attack complexity is high, indicating that specific conditions must be met for successful exploitation. However, when exploited, the vulnerability can result in high impact to both confidentiality and integrity of the vulnerable system, as well as subsequent systems in the network. The scope is changed, meaning the vulnerability can affect resources beyond the vulnerable component's security scope.

Root Cause

The vulnerability stems from insufficient validation and sanitization of user-supplied path inputs in DX NetOps Spectrum. The application fails to properly restrict pathname resolution, allowing directory traversal sequences such as ../ to escape the intended directory structure. This improper limitation enables attackers to reference files and directories outside the expected scope.

Attack Vector

The attack vector is network-based, requiring the attacker to have low-level authentication to the DX NetOps Spectrum application. An attacker can craft malicious requests containing path traversal sequences to access files outside the application's intended directory. Typical exploitation involves manipulating parameters that accept file paths or directory names.

The vulnerability mechanism involves injecting traversal sequences (e.g., ../, ..\, or URL-encoded variants) into user-controllable input fields that are used to construct file system paths. When the application processes these malicious inputs without proper sanitization, it resolves the path to locations outside the intended directory, potentially exposing sensitive configuration files, credentials, or system files.

Detection Methods for CVE-2025-69267

Indicators of Compromise

• HTTP/HTTPS requests containing path traversal sequences such as ../, ..\, %2e%2e%2f, or %2e%2e/ targeting DX NetOps Spectrum endpoints
• Unusual file access patterns in application logs showing access to files outside expected directories
• Access attempts to sensitive system files like /etc/passwd, web.config, or application configuration files
• Anomalous authenticated sessions with high volumes of file-related requests

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block common path traversal patterns in HTTP requests
• Enable detailed logging on DX NetOps Spectrum and monitor for suspicious file path access attempts
• Deploy intrusion detection systems (IDS) with signatures for directory traversal attack patterns
• Review application logs for error messages indicating file access failures outside normal directories

Monitoring Recommendations

• Monitor authentication logs for unusual login patterns followed by file access requests
• Configure alerting for attempts to access sensitive system configuration files
• Implement file integrity monitoring on critical system directories
• Track network traffic to DX NetOps Spectrum instances for anomalous request patterns

How to Mitigate CVE-2025-69267

Immediate Actions Required

• Review the Broadcom Security Advisory #36756 for vendor-specific guidance
• Restrict network access to DX NetOps Spectrum management interfaces using firewall rules
• Implement additional authentication controls and limit user privileges to minimize attack surface
• Enable comprehensive logging to detect exploitation attempts

Patch Information

Broadcom has released security advisory #36756 addressing this vulnerability. Organizations running DX NetOps Spectrum version 24.3.8 or earlier should consult the Broadcom Security Advisory for patch availability and upgrade instructions. Apply the recommended patches or upgrade to a fixed version as soon as possible.

Workarounds

• Implement network segmentation to limit access to DX NetOps Spectrum from untrusted networks
• Deploy a web application firewall (WAF) to filter malicious requests containing path traversal sequences
• Review and restrict user permissions to minimize the impact of potential exploitation
• Consider temporarily disabling vulnerable features if identified in the security advisory until patches can be applied

# Example: Implement basic WAF rule for path traversal patterns (generic example)
# Block requests containing common traversal sequences
# Adjust based on your specific WAF solution

# For iptables-based rate limiting of suspicious traffic
iptables -A INPUT -p tcp --dport 443 -m string --string "../" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 80 -m string --string "../" --algo bm -j DROP
