Recent Vulnerabilities in SAP GUI Demand Immediate Attention
Cybersecurity researchers have identified two serious vulnerabilities in the SAP Graphical User Interface (GUI) for Windows and Java, potentially exposing sensitive user data. Patched in January 2025 (CVE-2025-0055 and CVE-2025-0056), these flaws stem from insecure storage of user input history.
Key Details
- Who: SAP
- What: Two vulnerabilities in SAP GUI’s input history feature.
- When: Patched in January 2025.
- Where: Affecting the local storage on Windows and Java versions of SAP GUI.
- Why: User input history is saved insecurely and can be accessed by unauthorized individuals.
- How: Input history includes sensitive data, stored with weak encryption or unencrypted, making it easy to extract.
Why It Matters
These vulnerabilities can severely impact enterprise security by allowing unauthorized access to sensitive information such as usernames, IDs, and bank account details. The weak XOR-based encryption used in SAP GUI for Windows and the unencrypted Java version elevate the risks, particularly for enterprises relying on these systems for sensitive operations.
The threat landscape is exacerbated by potential exploits involving human intervention, such as USB-based attacks or social engineering tactics targeting individuals with access to these systems. This lowers the security posture of organizations using SAP products, particularly in industries dealing with high volumes of sensitive data.
Takeaway for IT Teams
To mitigate these risks, IT professionals should disable the input history functionality and delete existing sensitive data files from affected directories. Regularly updating systems and monitoring for threats will be crucial to maintain security.
For organizations utilizing SAP GUI, implementing strict access controls and training employees on security hygiene can further reduce potential exposure.
