The vulnerability identified as CVE-2006-6157 represents a critical sql injection flaw within the ContentNow content management system version 1.39 and earlier. This vulnerability specifically targets the index.php script and exploits improper input validation mechanisms that fail to sanitize user-supplied data before incorporating it into sql queries. The affected parameter pageid serves as the primary attack vector, allowing malicious actors to inject arbitrary sql commands that execute within the database context of the application. This type of vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a serious security flaw that enables unauthorized data access and manipulation.
The technical exploitation of this vulnerability occurs when an attacker submits malicious input through the pageid parameter, bypassing normal input validation controls. The application fails to properly escape or filter special sql characters and keywords, allowing attackers to manipulate the intended sql query structure. When the application processes an invalid pageid parameter, it can inadvertently disclose file system paths through error messages or response handling mechanisms, providing additional information that could aid in further exploitation attempts. This path disclosure capability extends the attack surface beyond simple sql injection to include information disclosure vulnerabilities that align with attack techniques documented in the mitre attack framework.
The operational impact of this vulnerability is severe as it provides remote attackers with the ability to execute arbitrary sql commands on the affected database server. Attackers can potentially extract sensitive data, modify database content, create new database users, or even escalate privileges within the application environment. The path disclosure aspect further compounds the risk by revealing internal system information that could be used to plan more sophisticated attacks against the application or underlying infrastructure. This vulnerability affects organizations using ContentNow 1.39 and earlier versions, potentially compromising the confidentiality, integrity, and availability of their content management systems.
Mitigation strategies for CVE-2006-6157 should prioritize immediate patching of the ContentNow application to version 1.40 or later, which contains the necessary security fixes. Organizations should implement proper input validation and output encoding mechanisms to prevent sql injection attacks, including the use of prepared statements or parameterized queries. Additionally, web application firewalls should be configured to monitor and block suspicious sql injection patterns targeting the pageid parameter. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components, while network segmentation and access controls can help limit the potential damage from successful exploitation attempts. The vulnerability demonstrates the critical importance of maintaining up-to-date software versions and implementing robust input validation controls as recommended by security best practices and industry standards.
