CVE-2005-1136 in sphpBlog
Summary
by MITRE
Simple PHP Blog (sphpBlog) 0.4.0 stores the (1) password.txt and (2) config.txt files under the web document root, which allows remote attackers to obtain sensitive information and crack passwords via a direct request to these files.

The vulnerability identified as CVE-2005-1136 affects Simple PHP Blog version 0.4.0, representing a critical misconfiguration that exposes sensitive system files to unauthorized access. This flaw demonstrates poor security practices in file placement and access control within the web application architecture, creating an avenue for information disclosure that directly impacts the system's confidentiality and integrity. The vulnerability resides in the application's default configuration where critical authentication and configuration files are stored in publicly accessible directories rather than being secured within the server's protected file system.
The technical implementation of this vulnerability stems from the application's improper file management approach, where password.txt and config.txt files containing authentication credentials and system configuration parameters are placed within the web document root directory. This configuration allows any remote attacker with knowledge of the application's file structure to directly request these files through standard http protocols, bypassing any intended access controls or authentication mechanisms. The flaw operates at the file system level and represents a classic example of insecure file placement, where sensitive data is stored in locations accessible to unauthenticated users.
The operational impact of this vulnerability is severe and multifaceted, as it enables attackers to obtain complete system credentials and configuration details that can be used for further exploitation. Once an attacker gains access to the password.txt file, they can attempt password cracking attacks against the stored credentials, potentially gaining unauthorized access to the blog administration interface. The config.txt file exposure provides additional sensitive information that could reveal database connection details, system paths, or other configuration parameters that aid in subsequent attack phases. This vulnerability directly violates the principle of least privilege and demonstrates a lack of proper information security controls.
This vulnerability aligns with CWE-275 permission issues and specifically relates to CWE-532 information exposure through file system access. The flaw also corresponds to ATT&CK technique T1083 file and directory discovery, where attackers systematically identify and access sensitive files within compromised systems. The attack vector represents a reconnaissance phase that enables privilege escalation and persistent access to the vulnerable system, potentially allowing attackers to establish backdoors or conduct further malicious activities within the network.
The recommended mitigations for this vulnerability involve immediate reconfiguration of the application's file storage locations to ensure sensitive files are placed outside the web document root directory and are properly secured with appropriate access controls. System administrators should implement proper file permissions that restrict access to these critical files to authorized personnel only, typically requiring root or administrator privileges. Additionally, the application should be updated to a newer version that addresses this configuration issue or patched to ensure proper file placement and access controls are enforced. Regular security audits should verify that no sensitive files are accessible through web requests, and automated scanning tools should be deployed to detect similar misconfigurations across the entire application infrastructure.
