CVE-2008-0290 in DigitalHive
Summary
by MITRE
Multiple SQL injection vulnerabilities in Digital Hive 2.0 RC2 and earlier allow (1) remote attackers to execute arbitrary SQL commands via the selectskin parameter to an unspecified program, or (2) remote authenticated administrators to execute arbitrary SQL commands via the user_id parameter in the gestion_membre.php page to base.php.

The vulnerability described in CVE-2008-0290 represents a critical SQL injection flaw affecting Digital Hive 2.0 RC2 and earlier versions. This vulnerability manifests through two distinct attack vectors that collectively demonstrate the dangerous nature of improper input validation in web applications. The first vector targets unauthenticated remote attackers who can exploit the selectskin parameter within an unspecified program, while the second vector targets authenticated administrators who can leverage the user_id parameter in gestion_membre.php to reach base.php. Both attack paths ultimately enable arbitrary SQL command execution, representing a fundamental breakdown in the application's security architecture.
The technical flaw underlying this vulnerability stems from the application's failure to properly sanitize or escape user-supplied input before incorporating it into SQL queries. This classic SQL injection vulnerability occurs when the application directly concatenates user-provided data into database queries without adequate validation or parameterization. The selectskin parameter and user_id parameter serve as entry points where attacker-controlled data flows directly into the SQL execution context, bypassing all input validation mechanisms. This weakness aligns with CWE-89, which specifically addresses SQL injection vulnerabilities, and demonstrates how insufficient input sanitization creates pathways for malicious data manipulation.
The operational impact of this vulnerability extends beyond simple data theft, as it allows attackers to execute arbitrary commands on the underlying database system. Remote attackers can potentially gain unauthorized access to sensitive data, modify database contents, or even escalate privileges within the database environment. Authenticated administrators who exploit the second vulnerability can leverage their existing access to further compromise the system, potentially leading to complete system takeover. The implications are particularly severe given that the vulnerability affects both unauthenticated and authenticated attack scenarios, widening the potential attack surface significantly. This vulnerability directly maps to ATT&CK technique T1071.004 for application layer protocol manipulation and T1190 for exploitation of remote services.
Mitigation strategies for this vulnerability must address both the immediate code-level issues and broader architectural security concerns. The primary solution involves implementing proper parameterized queries or prepared statements throughout the application to ensure that user input cannot alter the structure of SQL commands. All input parameters, particularly those used in database operations, must undergo rigorous validation and sanitization before processing. Additionally, implementing the principle of least privilege for database accounts, limiting administrative access, and employing proper input filtering mechanisms such as input whitelisting can significantly reduce the impact of such vulnerabilities. Regular security audits, code reviews focusing on database interaction patterns, and maintaining updated application versions are essential defensive measures. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for exploitation attempts targeting known SQL injection patterns.
