The vulnerability identified as CVE-2007-0527 represents a critical sql injection flaw within the Website Baker content management system version 2.6.5 and earlier. This vulnerability specifically targets the is_remembered function located in the class.login.php file, which handles user authentication and session management. The flaw occurs when the system processes the REMEMBER_KEY cookie parameter without proper input validation or sanitization, creating an exploitable entry point for remote attackers to manipulate the underlying database queries. This vulnerability falls under the CWE-89 category of sql injection, which is classified as a serious weakness in software security architecture. The ATT&CK framework categorizes this as a command injection technique that can lead to complete system compromise through database manipulation.
The technical implementation of this vulnerability stems from improper parameter handling within the authentication flow of Website Baker. When users access the system, the REMEMBER_KEY cookie is used to maintain persistent login sessions across browser sessions. However, the is_remembered function fails to properly escape or parameterize the cookie value before incorporating it into sql queries. This allows attackers to inject malicious sql fragments that can alter the intended query execution path. The vulnerability is particularly dangerous because it operates at the authentication layer, meaning successful exploitation could grant attackers unauthorized access to user accounts and potentially escalate privileges to administrative levels.
The operational impact of this vulnerability extends beyond simple data theft or manipulation. Remote attackers can execute arbitrary sql commands on the database server, potentially leading to complete system compromise. Attackers may extract sensitive user credentials, personal information, or even modify core system data. The vulnerability's remote nature means that exploitation does not require local access to the system, making it particularly dangerous for web applications. Depending on the database configuration and user permissions, attackers could potentially gain access to additional system resources or escalate their privileges through database-level commands. This vulnerability directly impacts the confidentiality, integrity, and availability of the affected system, representing a fundamental breakdown in the application's security controls.
Mitigation strategies for CVE-2007-0527 should focus on immediate patching of the Website Baker application to version 2.6.6 or later, which contains the necessary fixes for the sql injection vulnerability. Organizations should implement proper input validation and parameterized queries throughout the application to prevent similar issues in other components. The principle of least privilege should be enforced by ensuring database user accounts have minimal required permissions, preventing attackers from executing dangerous sql commands even if injection occurs. Additionally, network-based intrusion detection systems should be configured to monitor for suspicious sql patterns and unusual authentication attempts. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in other applications and components of the system infrastructure.
