1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-1495 affects SAP NetWeaver AS for ABAP and ABAP Platform (Internet Communication Framework). The issue arises from weak access controls, allowing an attacker to access restricted information. This vulnerability has a significant impact on the confidentiality, integrity, and availability of the application.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 9.9 indicates a critical vulnerability. The vector string breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it does not require specialized conditions.
• PR:L (Low): The attacker requires low privileges to exploit the vulnerability.
• UI:N (None): No user interaction is required.
• S:C (Changed): The vulnerability affects the confidentiality, integrity, and availability of the system.
• C:H (High), I:H (High), A:H (High): The impact on confidentiality, integrity, and availability is high.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Network-based Attacks: An attacker can exploit the vulnerability remotely over the network.
• Low Privilege Exploitation: The attacker needs only low-level privileges to exploit the vulnerability, which can be obtained through phishing, social engineering, or other low-level attacks.
• Automated Exploitation: Due to the low complexity, automated scripts or bots could be used to exploit the vulnerability en masse.

Exploitation Methods:

• Information Disclosure: The attacker can access restricted information, leading to data breaches.
• Privilege Escalation: The attacker might use the accessed information to escalate privileges within the system.
• Data Manipulation: The attacker can potentially alter data, affecting the integrity of the system.

3. Affected Systems and Software Versions

The vulnerability affects multiple versions of SAP NetWeaver AS for ABAP and ABAP Platform (Internet Communication Framework):

• SAP_BASIS 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757, 758, 912, 913, 914
