The vulnerability described in CVE-2003-0752 represents a critical sql injection flaw within the AttilaPHP 3.0 content management system that affects remote attackers capable of manipulating the cook_id parameter. This vulnerability specifically targets the global.php3 file which serves as a central component in the application's authentication and session management processes. The flaw enables malicious actors to bypass authentication mechanisms by exploiting improper input validation and sanitization techniques in the parameter handling code.
The technical implementation of this vulnerability stems from the application's failure to properly sanitize user-supplied input from the cook_id parameter before incorporating it into sql query constructs. When the system processes this parameter, it directly concatenates user data into database queries without adequate filtering or escaping mechanisms. This creates an environment where attackers can inject malicious sql code that manipulates the intended query execution flow. The vulnerability operates under the well-established CWE-89 category for sql injection, which is classified as a direct database injection attack vector that allows unauthorized access to database resources.
From an operational impact perspective, this vulnerability presents a severe security risk as it allows remote attackers to completely circumvent the application's authentication system without requiring valid credentials. The exploitation process typically involves crafting a malicious cook_id parameter value that, when processed by the vulnerable global.php3 script, modifies the sql query to return true for authentication checks or to extract administrative privileges. This type of vulnerability falls under the ATT&CK technique T1190 for exploitation of remote services and T1078 for valid accounts, as it enables unauthorized access to privileged system resources through manipulated session identifiers.
The attack vector for this vulnerability is particularly concerning as it requires no prior authentication and can be executed over the network without requiring physical access to the system. Attackers can simply modify the cook_id parameter in their browser or through automated tools to inject malicious sql payloads that exploit the vulnerable input handling. The affected versions of AttilaPHP 3.0 and potentially earlier releases represent a significant security gap since the vulnerability persists across multiple versions, indicating a fundamental flaw in the application's input processing architecture that was not adequately addressed through version updates.
Mitigation strategies for this vulnerability should include immediate implementation of parameterized queries or prepared statements to prevent sql injection attacks, comprehensive input validation and sanitization of all user-supplied parameters including cook_id, and the application of proper escape sequences for sql special characters. Organizations should also implement web application firewalls to monitor and filter malicious sql injection attempts, conduct regular security code reviews to identify similar input handling vulnerabilities, and ensure all systems are updated to patched versions of AttilaPHP that address this specific vulnerability. Additionally, implementing proper session management practices and regular security assessments can help prevent exploitation of similar authentication bypass vulnerabilities in other system components.
