Description

SAP NetWeaver Visual Composer contains a Directory Traversal vulnerability caused by insufficient validation of input paths provided by a high-privileged user. This allows an attacker to read or modify arbitrary files, resulting in a high impact on confidentiality and a low impact on integrity.

Technical Analysis

CVE-2025-42977 is a directory traversal vulnerability identified in SAP NetWeaver Visual Composer, specifically affecting version VCBASE 7.50. The vulnerability arises due to improper validation of input paths by the application, which allows a high-privileged user to manipulate pathname inputs to access files outside the intended restricted directories. This weakness is classified under CWE-22, indicating an improper limitation of a pathname to a restricted directory. Exploiting this vulnerability enables an attacker to read or modify arbitrary files on the affected system. The vulnerability has a CVSS v3.1 base score of 7.6, reflecting a high severity level. The vector details indicate that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality is high (C:H), as sensitive files can be read, while integrity impact is low (I:L), and availability is not affected (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because SAP NetWeaver Visual Composer is a widely used tool for developing business applications within SAP environments, and unauthorized file access could lead to leakage of sensitive business data or configuration files, potentially enabling further attacks or data breaches.

Potential Impact

For European organizations, the impact of CVE-2025-42977 can be substantial, especially for enterprises relying on SAP NetWeaver Visual Composer for critical business processes. Confidentiality breaches could expose sensitive corporate data, intellectual property, or personal data protected under GDPR, leading to regulatory penalties and reputational damage. Although the integrity impact is low, unauthorized file modifications could still disrupt business operations or compromise system configurations. The requirement for high privileges to exploit the vulnerability somewhat limits the attack surface to insiders or attackers who have already gained elevated access, but this does not eliminate the risk, as privilege escalation or insider threats are common vectors. The lack of user interaction needed means that once high privileges are obtained, exploitation can be automated or performed stealthily. Given the interconnected nature of SAP systems in European enterprises, a successful exploit could cascade into broader system compromises or data leaks affecting multiple departments or subsidiaries.

Mitigation Recommendations

Organizations should implement the following specific mitigation measures: 1) Immediately audit and restrict high-privileged user access to SAP NetWeaver Visual Composer, ensuring the principle of least privilege is enforced. 2) Monitor and log all file access activities by privileged users to detect anomalous behavior indicative of exploitation attempts. 3) Apply strict input validation and sanitization controls on pathname inputs within SAP environments, if custom extensions or configurations are used. 4) Coordinate with SAP support channels to obtain and apply official patches or hotfixes as soon as they become available. 5) Conduct regular vulnerability assessments and penetration testing focusing on directory traversal and path manipulation vectors within SAP systems. 6) Employ network segmentation and access controls to limit exposure of SAP NetWeaver Visual Composer instances to trusted internal networks only. 7) Educate system administrators and users with elevated privileges about the risks and signs of exploitation related to this vulnerability. These targeted actions go beyond generic advice by focusing on access control, monitoring, and proactive patch management tailored to the SAP environment.
