Description Preview
Two memory corruption vulnerabilities (CWE-787) have been identified in multiple Aruba CX Switch Series models including 6200F, 6300, 6400, 8320, 8325, and 8400. These vulnerabilities affect firmware versions prior to 10.04.1000. If successfully exploited, an attacker could cause a Local Denial of Service of the Cisco Discovery Protocol (CDP) process running on the affected switches, potentially disrupting network discovery and management capabilities.
Overview
The vulnerabilities exist in the CDP (Cisco Discovery Protocol) process implementation of Aruba CX Switches. CDP is a Layer 2 protocol used for network discovery that allows devices to share information with directly connected devices. The memory corruption issues (classified as CWE-787, which refers to out-of-bounds write vulnerabilities) could allow an attacker to crash the CDP process, resulting in a denial of service condition. This affects the switch's ability to discover and communicate with neighboring network devices using CDP.
Remediation
Organizations using affected Aruba CX Switch models should:
- Upgrade firmware to version 10.04.1000 or later as recommended by Aruba Networks
- If immediate patching is not possible, consider temporarily disabling the CDP process if it's not critical to network operations
- Implement network segmentation to limit potential attack vectors
- Monitor switch logs for any unusual behavior related to the CDP process
- Follow vendor-specific security best practices for Aruba network equipment
