CVE-2019-5401 in HP2910al-48G
Summary
by MITRE
A potential security vulnerability has been identified in HP2910al-48G version W.15.14.0016. The attack exploits an xss injection by setting the attack vector in one of the switch persistent configuration fields (management URL, location, contact). But admin privileges are required to configure these fields thereby reducing the likelihood of exploit. HPE Aruba has provided firmware updates to resolve the vulnerability in HP 2910-48G al Switch. Please update to W.15.14.0017.

This vulnerability exists within the HP 2910al-48G network switch firmware version W.15.14.0016 and represents a cross-site scripting flaw that could potentially allow malicious actors to inject malicious code into persistent configuration fields. The vulnerability specifically affects management URL, location, and contact fields that are used for switch configuration and administration purposes. These fields are designed to store persistent configuration data that can be accessed by administrators during routine switch management activities. The security flaw allows an attacker to inject malicious scripts that could execute when the configuration data is displayed to users, creating a potential vector for session hijacking, credential theft, or further network compromise.
The technical exploitation of this vulnerability requires administrative privileges to modify the affected configuration fields, which significantly reduces the attack surface and overall exploitability. This requirement means that the vulnerability cannot be exploited by unauthenticated attackers or those without proper administrative access to the switch configuration interface. However, the presence of this flaw still represents a serious security concern, particularly in environments where privileged accounts might be compromised or where social engineering attacks could potentially gain administrative access. The vulnerability aligns with CWE-79 Cross-site Scripting which specifically addresses the injection of malicious scripts into web applications, and it could potentially map to ATT&CK technique T1059.007 Command and Scripting Interpreter for executing malicious code through compromised administrative sessions.
The operational impact of this vulnerability extends beyond simple script injection, as it could enable attackers who have gained administrative access to escalate their privileges further within the network infrastructure. Network switches serve as critical components in network architecture, and compromise of switch configuration fields could provide attackers with insights into network topology, administrative access points, and potentially facilitate lateral movement within the network. The vulnerability affects the integrity of switch management interfaces and could lead to unauthorized modifications of switch settings, potentially disrupting network operations or creating backdoor access points. Organizations relying on these switches for network management and monitoring could face significant risks if the vulnerability is exploited, particularly in environments where switch configuration data is exposed to multiple administrators or where proper access controls are not maintained.
The recommended mitigation strategy involves immediate deployment of firmware update W.15.14.0017 provided by HPE Aruba to address the identified cross-site scripting vulnerability. This firmware update resolves the injection flaw in the persistent configuration fields and restores proper input validation mechanisms. Organizations should also implement additional security measures such as restricting administrative access to only trusted personnel, implementing multi-factor authentication for switch management interfaces, and conducting regular security assessments of network infrastructure components. Network administrators should review and audit existing switch configurations to ensure that no malicious code has been previously injected into the affected fields. The update process should be carefully planned to minimize network disruption while ensuring all affected switches receive the necessary security patches. Additionally, organizations should consider implementing network monitoring solutions to detect any anomalous behavior that might indicate exploitation attempts or unauthorized modifications to switch configurations.
