Comprehensive Technical Analysis of EUVD-2025-23412
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-23412 pertains to the "Files" module, which is used for managing files within spaces and user profiles. Versions 0.16.9 and below are affected by a lack of logic to prevent the exploitation of backend SQL queries, potentially allowing unauthorized data access. This issue has been addressed in version 0.16.10.
Severity Evaluation:
- Base Score: 9.2
- Base Score Version: 4.0
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N
The CVSS score of 9.2 indicates a critical vulnerability. The high confidentiality impact (VC:H) and scope change (SC:H) suggest that an attacker could gain significant access to sensitive data, potentially affecting multiple users or systems.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network Access (AV:N): The vulnerability can be exploited remotely over the network.
- Low Complexity (AC:L): The attack does not require specialized access conditions beyond the network.
- No Authentication (AT:N): The attacker does not need to be authenticated to exploit the vulnerability.
- No User Interaction (UI:N): The attack does not require any user interaction.
Exploitation Methods:
- SQL Injection: An attacker could craft malicious SQL queries to extract sensitive data from the backend database.
- Data Exfiltration: By exploiting the vulnerability, an attacker could exfiltrate confidential information, including user data and system configurations.
3. Affected Systems and Software Versions
Affected Software:
- Product: cfiles
- Vendor: humhub
- Versions: < 0.16.10
All systems running the "Files" module version 0.16.9 and below are vulnerable. It is crucial to identify and update these systems to version 0.16.10 or later to mitigate the risk.
4. Recommended Mitigation Strategies
Immediate Actions:
- Update Software: Upgrade the "Files" module to version 0.16.10 or later.
- Patch Management: Implement a robust patch management process to ensure timely updates of all software components.
