CVE-2006-4118 in GeheimChaos
Summary
by MITRE
Multiple SQL injection vulnerabilities in GeheimChaos 0.5 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) Temp_entered_login or (2) Temp_entered_email parameters to (a) gc.php, and in multiple parameters in (b) include/registrieren.php, possibly involving the (3) $form_email, (4) $form_vorname, (5) $form_nachname, (6) $form_strasse, (7) $form_plzort, (8) $form_land, (9) $form_homepage, (10) $form_bildpfad, (11) $form_profilsichtbar, (12) $Temp_sprache, (13) $form_tag, (14) $form_monat, (15) $form_jahr, (16) $Temp_akt_string, (17) $form_icq, (18) $form_msn, (19) $form_yahoo, (20) $form_username, and (21) $Temp_form_pass variables.

The vulnerability described in CVE-2006-4118 represents a critical SQL injection flaw affecting GeheimChaos version 0.5 and earlier. This vulnerability resides in the web application's handling of user input parameters, specifically within the core authentication and registration modules. The flaw allows remote attackers to inject malicious SQL commands through multiple entry points, fundamentally compromising the database security and potentially leading to full system compromise. The vulnerability affects both the main gc.php script and the include/registrieren.php file, creating multiple attack vectors that significantly increase the exploitability of the system.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's PHP scripts. Attackers can manipulate the Temp_entered_login and Temp_entered_email parameters in gc.php to inject malicious SQL code, while the registration process in registrieren.php contains numerous vulnerable variables including form_email, form_vorname, form_nachname, and others. These parameters are directly incorporated into SQL queries without proper escaping or parameterization, creating a classic SQL injection scenario that follows the CWE-89 weakness classification. The vulnerability demonstrates poor input handling practices that violate fundamental secure coding principles and security best practices established by organizations such as OWASP.
The operational impact of this vulnerability extends far beyond simple data theft, as it provides attackers with the capability to execute arbitrary SQL commands on the underlying database server. This level of access enables unauthorized users to extract sensitive information, modify database contents, delete records, or even escalate privileges to gain administrative control over the entire system. The vulnerability affects critical user registration and authentication processes, potentially allowing attackers to create malicious accounts, bypass authentication mechanisms, or gain access to user credentials and personal information. The multi-parameter nature of the vulnerability increases the attack surface significantly, making it easier for adversaries to find successful exploitation paths.
Mitigation strategies for this vulnerability should focus on implementing proper input validation, parameterized queries, and secure coding practices throughout the application. The most effective immediate solution involves implementing prepared statements or parameterized queries for all database interactions, ensuring that user input is properly escaped and validated before being processed. Organizations should also implement proper input sanitization routines that filter out potentially malicious characters and patterns. Additionally, regular security audits and code reviews should be conducted to identify similar vulnerabilities in other parts of the application. The remediation efforts should align with NIST SP 800-160 guidelines for secure software development and follow ATT&CK framework techniques for preventing SQL injection attacks, particularly those related to command execution and credential access. Regular updates and patch management processes should be established to prevent similar vulnerabilities from being introduced in future versions of the software.
