The vulnerability identified as CVE-2008-6875 represents a critical sql injection flaw within the default.asp component of an asp product catalog application. This vulnerability specifically targets the cid parameter, which serves as an entry point for malicious actors to manipulate database queries through crafted input. Unlike similar vulnerabilities such as CVE-2007-5220, this particular flaw operates through a distinct attack vector that exploits improper input validation mechanisms within the application's default.asp script. The vulnerability resides in the application's failure to properly sanitize user-supplied data before incorporating it into sql command structures, creating an avenue for unauthorized database access and manipulation.
The technical implementation of this vulnerability stems from the application's direct concatenation of user input from the cid parameter into sql queries without adequate sanitization or parameterization. When an attacker submits malicious input through the cid parameter, the application processes this data without proper validation, allowing sql commands embedded within the input to be executed with the privileges of the database user account. This flaw falls under the common weakness enumeration CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is incorporated into sql queries without proper escaping or parameterization. The vulnerability demonstrates a classic lack of input validation and output encoding practices that are fundamental to preventing sql injection attacks in web applications.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete database compromise and potential system infiltration. Remote attackers can leverage this weakness to execute arbitrary sql commands, potentially gaining access to sensitive customer information, product catalogs, and other database contents. The vulnerability enables attackers to perform read operations on the database, modify existing records, insert new data, or even delete entire tables depending on the database user's privileges. In a production environment, this could lead to significant data breaches, financial losses, and regulatory compliance violations. The attack surface is particularly concerning as it allows for remote exploitation without requiring any authentication credentials, making it an attractive target for automated scanning tools and malicious actors seeking to compromise web applications.
Mitigation strategies for CVE-2008-6875 must focus on implementing proper input validation and parameterized queries throughout the application code. The most effective remediation involves replacing direct string concatenation of user input with parameterized sql queries that separate the sql command structure from the data being processed. Organizations should implement strict input validation routines that filter or reject potentially malicious characters and patterns before any data processing occurs. Additionally, the principle of least privilege should be enforced by ensuring database accounts used by the application have minimal required permissions, preventing attackers from executing destructive operations even if they successfully exploit the vulnerability. Regular security assessments and code reviews should be conducted to identify similar injection vulnerabilities within the application and ensure that all user-supplied data is properly sanitized before database interaction. The mitigation approach aligns with defensive techniques outlined in the mitre attack framework under the execution and credential access tactics, emphasizing the importance of input validation and privilege separation as primary defense mechanisms against sql injection attacks.
