Overview of CVE-2025-20002
In early 2025, a security vulnerability identified as CVE-2025-20002 was disclosed, affecting GMOD Apollo versions lower than 2.8.0. This vulnerability, assigned to ICS-CERT, allows local path information disclosure when attempting to upload files not meeting specific prerequisites. The flaw arises due to the generation of error messages that inadvertently divulge sensitive local path information, categorized under CWE-209.
Understanding the Security Impact
Analyzed using CVSS versions 3.1 and 4.0, CVE-2025-20002 has been rated with a base score of 5.3 and 6.9, respectively, indicating a medium severity. The outlined vector is as follows:
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: None
- User Interaction: None
- Confidentiality Impact: Low
- Integrity Impact: None
- Availability Impact: None
Despite the medium severity rating, the ease of attack due to a low complexity and network vector increases the urgency for a remediation strategy, especially for organizations reliant on GMOD Apollo.
Mitigation Strategies
The recommended remediation is to upgrade GMOD Apollo to version 2.8.0 or later. This update addresses the identified vulnerability by enhancing how error messages are managed, reducing the risk of accidentally disclosing sensitive path information. For users facing challenges with upgrading, the following interim actions are suggested:
- Review Permissions: Ensure that file upload permissions are restricted to trusted personnel only, thereby minimizing exposure to inadvertent uploads.
- Monitor Network Traffic: Regular analysis of logs and network traffic may detect unauthorized access attempts or uploads, allowing for timely interventions.
- Employ Web Application Firewalls: A WAF can effectively filter malicious requests, preventing attempts to exploit this vulnerability.
Conclusion
By proactively addressing CVE-2025-20002, organizations can safeguard against data leaks through improper error message handling. Timely updates and adherence to robust security practices ensure data integrity and confidentiality, reinforcing trust in GMOD Apollo’s deployment.
