Summary
There are several vulnerabilities fixed in a recent HPE Aruba Networking security advisory which details multiple critical remote code execution (RCE) vulnerabilities. There are 4 critical vulnerabilities total:
- CVE-2024-26305 (CVSSv3: 9.8) – Buffer overflow vulnerability by the Utility daemon leading to unauthenticated RCE utilizing specifically crafted packets sent to the PAPI (Aruba’s access point management protocol) over port 8211. Exploitation allows for the ability to execute arbitrary code as a privileged user on the operating system.
- CVE-2204-26304 (CVSSv3: 9.8) - Buffer overflow vulnerability in the L2/L3 Managment service leading to unauthenticated RCE utilizing specifically crafted packets sent to the PAPI over port 8211.
- CVE-2024-33511 (CVSSv3: 9.8) - Buffer overflow vulnerability in the Automatic Reporting service leading to unauthenticated RCE utilizing specifically crafted packets sent to the PAPI over port 8211.
- CVE-2024-33512 (CVSSv3: 9.8) - Buffer overflow vulnerability in the Local User Authentication Database service leading to unauthenticated RCE utilizing specifically crafted packets sent to the PAPI over port 8211.
There is no evidence of these vulnerabilities being exploited as of right now according to the advisory.
Impact Assessment
Impact of these vulnerabilities if exploited would be extremely high, allowing a remote, unauthenticated attacker to execute arbitrary code on targeted machines. The only positive aspect is that there is currently no evidence of active exploitation according to HPE Aruba Networking. This should be a high priority patch, but not an emergency.
Remediation
According to the security advisory, upgrading the ArubaOS versions on Mobility Controllers, Mobility Conductors, and Gateway to one of the following versions will resolve all the vulnerabilities listed. The downloads for these can be found in the HPE Networking Support Portal.
- ArubaOS 10.6.x.x: 10.6.0.0 and above
- ArubaOS 10.5.x.x: 10.5.1.1 and above
- ArubaOS 10.4.x.x: 10.4.1.1 and above
- ArubaOS 8.11.x.x: 8.11.2.2 and above
- ArubaOS 8.10.x.x: 8.10.0.11 and above
- ArubaOS 8.10.x.x: 8.10.0.11 and above
What It Means for You
If you are a user of any ArubaOS capable devices or utilize it in any capacity; refer to the security advisory to see if you are affected by any of the vulnerabilities. If you are, a plan should be made to upgrade the operating system in a timely manner.
Business Implications
Exploitation of this vulnerability can allow for RCE on any device with a vulnerable version of ArubaOS. Any device utilizing this operating system is in a business-critical position as it is used with network architecture. If exploited the attacker could deny access to essential business resources, exfiltrate data, perform lateral movement through the environment, and install malware. There will be a hefty monetary, data, and reputational loss if any of these vulnerabilities are leveraged against your organization.
Access Point Consulting Recommends
Patch: We recommend patching this vulnerability as soon as possible, it affects critical network architecture and allows for remote code execution.
Monitor traffic: These vulnerabilities are exploited through port 8211, it is advised to monitor this port if you are on a vulnerable version for any unusual activity.
