CVE-2005-1586 in Quick.Forum
Summary
by MITRE
Quick.Forum 2.1.6 stores potentially sensitive information such as usernames, banned IP addresses, censored words, and backups under the web document root, which allows remote attackers to obtain that information via a direct request to (1) db/users.txt, (2) db/banList.txt, (3) db/censureWords.txt, or (4) backup files.

This vulnerability in Quick.Forum 2.1.6 represents a critical misconfiguration that exposes sensitive system information through improper file placement within the web document root directory. The flaw stems from the application's failure to properly secure administrative and operational data files, allowing unauthorized remote access to critical system components. The vulnerability specifically affects four distinct data files including db/users.txt which contains username information, db/banList.txt containing banned IP addresses, db/censureWords.txt with censored words, and various backup files that may contain additional sensitive data. This misconfiguration directly violates fundamental security principles of least privilege and proper data isolation, as administrative and operational data is made publicly accessible through standard web requests.
The technical exploitation of this vulnerability occurs through direct HTTP requests to specific file paths within the web root, making it particularly dangerous as it requires no authentication or specialized tools beyond basic web browsing capabilities. Attackers can simply append the vulnerable file paths to the target website's URL to access the sensitive information immediately. This type of vulnerability aligns with CWE-200, which addresses improper exposure of sensitive information, and represents a classic case of insecure direct object references where the application fails to properly validate access controls for file requests. The flaw demonstrates poor security architecture where administrative data is treated with the same access permissions as public web content, creating an information disclosure attack vector that can be exploited by any remote attacker.
The operational impact of this vulnerability extends beyond simple information disclosure, as the exposed data can enable more sophisticated attacks against the affected system. The usernames and IP addresses can be used for targeted social engineering attacks, while the censored words database may reveal system configuration details or content filtering policies. Backup files, in particular, often contain complete database dumps or system configurations that can provide attackers with comprehensive information about the application's internal structure and data relationships. This vulnerability directly maps to attack techniques in the ATT&CK framework under T1213, Information Discovery, and T1566, Phishing, as the exposed data can facilitate more targeted and effective social engineering campaigns. The exposure of banned IP addresses could also enable attackers to bypass security measures by understanding the system's threat detection patterns.
Organizations using Quick.Forum 2.1.6 should immediately relocate sensitive data files outside the web document root directory and implement proper access controls for all administrative files. The recommended mitigation strategy involves configuring the web server to prevent direct access to sensitive directories such as /db/ and /backup/, while ensuring that only authorized administrative users can access these resources through proper authentication mechanisms. Security configurations should include setting appropriate file permissions and implementing web server restrictions to prevent directory traversal attacks. Additionally, regular security audits should verify that no sensitive data remains accessible through web requests, and automated monitoring systems should be implemented to detect unauthorized access attempts to sensitive files. The vulnerability highlights the importance of following secure coding practices and proper security architecture principles, particularly in relation to the principle of least privilege and secure configuration management as outlined in various security standards including ISO 27001 and NIST cybersecurity frameworks.
