CVE-2006-6756 in Ixprim
Summary
by MITRE
The code function in install.fct.php in Ixprim 1.2 produces a guessable value of the confidential IXP_CODE in mainfile.php, which might allow remote attackers to gain access to the administration panel via a brute force attack.

The vulnerability identified as CVE-2006-6756 resides within the Ixprim 1.2 content management system where the install.fct.php script generates a predictable IXP_CODE value that gets stored in mainfile.php. This flaw represents a significant security weakness that directly impacts the system's authentication and access control mechanisms. The predictable nature of the generated code creates a vector for brute force attacks against the administrative interface, potentially allowing unauthorized users to gain elevated privileges and access sensitive system functions. This vulnerability type falls under CWE-330 Use of Insufficiently Random Values, which specifically addresses the use of predictable or insufficiently randomized data in security-critical contexts.
The technical implementation of this flaw occurs during the installation process where the system fails to generate cryptographically secure random values for the IXP_CODE parameter. When install.fct.php executes, it creates a value that follows predictable patterns or uses insufficient entropy sources, making it vulnerable to enumeration attacks. The generated code is then written to mainfile.php where it serves as a critical authentication element for accessing the administration panel. This design flaw demonstrates poor security practices in random number generation and credential management, as the system does not employ proper cryptographic methods to ensure the uniqueness and unpredictability of administrative access codes.
The operational impact of this vulnerability extends beyond simple unauthorized access as it enables attackers to systematically guess the administrative credentials through automated brute force mechanisms. Once an attacker successfully determines the IXP_CODE value, they gain full administrative privileges over the Ixprim system, potentially allowing them to modify content, access user data, install malicious software, or compromise the entire platform. This vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under T1110 Brute Force and T1078 Valid Accounts, where attackers leverage predictable credentials to maintain persistent access to target systems. The vulnerability affects the confidentiality, integrity, and availability of the affected system, creating a persistent threat that can remain undetected for extended periods.
Mitigation strategies for this vulnerability require immediate implementation of cryptographic secure random number generation during the installation process. System administrators should ensure that the IXP_CODE value is generated using cryptographically secure methods that provide sufficient entropy and unpredictability. The installation script must be updated to utilize proper randomization libraries and avoid predictable patterns or sequential numbering. Additionally, implementing account lockout mechanisms and rate limiting for authentication attempts can significantly reduce the effectiveness of brute force attacks. Organizations should also consider implementing multi-factor authentication and regular security audits to identify similar vulnerabilities in legacy systems. The remediation process should include generating new secure IXP_CODE values for existing installations and ensuring that all future deployments utilize secure randomization techniques that comply with industry standards for cryptographic security practices.
