CVE-2025-27452 in MEAC300-FNADE4
Summary
by MITRE • 07/03/2025
The configuration of the Apache httpd webserver which serves the MEAC300-FNADE4 web application, is partly insecure. There are modules activated that are not required for the operation of the FNADE4 web application. The functionality of the some modules
pose a risk to the webserver which enable dircetory listing.

The vulnerability identified as CVE-2025-27452 represents a critical misconfiguration issue within the Apache httpd webserver deployment serving the MEAC300-FNADE4 web application. This security weakness stems from the improper configuration where unnecessary modules remain enabled on the webserver, creating an expanded attack surface that significantly compromises the system's security posture. The presence of these redundant modules introduces multiple potential entry points for malicious actors while simultaneously exposing sensitive server functionality that should remain restricted. The configuration misalignment directly violates fundamental security principles of least privilege and defense in depth, as the webserver operates with unnecessary capabilities that extend beyond the functional requirements of the specific web application.
The technical flaw manifests through the activation of modules that are not essential for the FNADE4 web application's operation, creating inherent risks that can be exploited by threat actors. Specifically, the presence of modules that enable directory listing functionality poses a direct threat to information disclosure, allowing unauthorized users to traverse the file system structure and potentially access sensitive files, configuration data, or application source code. This directory listing vulnerability falls under CWE-548 Information Exposure Through Directory Listing, where the webserver inadvertently exposes directory contents without proper access controls. The flaw creates a pathway for attackers to enumerate server resources and identify potential targets for further exploitation, significantly increasing the attack surface and providing valuable reconnaissance data for more sophisticated attacks.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates multiple vectors for potential compromise of the web application and underlying infrastructure. When directory listing is enabled, attackers can discover backup files, temporary files, configuration backups, and other sensitive data that may contain credentials, database connection strings, or other confidential information. This exposure directly enables the attack pattern described in MITRE ATT&CK technique T1213.002 - Data from Information Repositories, where adversaries harvest data from repositories and information stores. The vulnerability also creates opportunities for attackers to identify application-specific files, version information, or implementation details that could be used to craft targeted attacks against the MEAC300-FNADE4 application. Additionally, the presence of unnecessary modules can introduce performance overhead and create additional points of failure within the webserver configuration.
Mitigation strategies for this vulnerability must focus on implementing proper configuration management and security hardening practices. The primary remediation involves disabling all Apache modules that are not explicitly required for the FNADE4 web application's operation, particularly those that enable directory listing functionality such as mod_autoindex or similar modules. Security administrators should conduct comprehensive module audits to identify and remove unused components, ensuring that only necessary modules remain enabled. The implementation should follow the principle of least privilege, where the webserver is configured with minimal required functionality to reduce the attack surface. Organizations should establish configuration baselines that align with industry standards such as the Center for Internet Security (CIS) Apache Benchmark, which provides specific recommendations for securing Apache httpd installations. Regular security assessments and automated configuration scanning should be implemented to prevent configuration drift and maintain the hardened state of the webserver environment. Additionally, implementing proper access controls, file permissions, and logging mechanisms will help detect and prevent unauthorized access attempts that could exploit this misconfiguration.
