How the Exploit Works

The attacker, by exploiting this broken access control vulnerability, can manipulate the process of how the firewall rules are applied in the EdgeConnect OS. This can potentially allow the attacker to route malicious traffic through the network, bypassing firewall protections and normal security checks. This could lead to unauthorized access to sensitive data or even full system compromise.

Conceptual Example Code

The following conceptual example showcases how an attacker might send malicious requests to a vulnerable endpoint:

POST /firewall/rule/bypass HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"new_rule": {
"rule_id": "1",
"action": "bypass",
"traffic_type": "all"
}
}

In this example, the attacker is attempting to create a new firewall rule that bypasses all traffic, effectively negating the firewall’s protection.

Mitigation Guidance

Users of HPE Aruba Networking EdgeConnect OS are advised to apply the latest vendor patches as soon as possible. If unable to patch immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be employed as a temporary mitigation measure to detect and block potential exploit attempts.
