The vulnerability identified as CVE-2007-4920 represents a critical SQL injection flaw within the PHP Webquest 2.5 content management system and earlier versions. This security weakness resides in the soporte_derecha_w.php script which processes user input through the id_actividad parameter, creating an avenue for malicious actors to manipulate database queries and potentially gain unauthorized access to sensitive information. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly filter or escape user-supplied data before incorporating it into SQL command structures.
This SQL injection vulnerability operates at the application layer and aligns with CWE-89 which specifically addresses improper neutralization of special elements used in SQL commands. The flaw allows remote attackers to execute arbitrary SQL commands against the underlying database system without authentication, potentially enabling full database compromise. The attack vector is particularly dangerous as it requires no prior authorization and can be exploited through standard web browser interactions. The id_actividad parameter serves as the primary entry point where malicious SQL payloads can be injected, bypassing normal application security controls and potentially leading to complete system compromise.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to modify database content, create new user accounts with administrative privileges, extract sensitive information including user credentials, and potentially establish persistent backdoors within the affected system. The vulnerability affects all versions of PHP Webquest up to and including version 2.5, indicating a long-standing security flaw that was not properly addressed in the software lifecycle. Organizations utilizing this platform face significant risk of data breaches, service disruption, and potential regulatory compliance violations due to the exposure of sensitive information through unauthorized database access.
Mitigation strategies for CVE-2007-4920 must focus on immediate remediation through input validation and parameterized query implementation. The most effective approach involves updating to a patched version of PHP Webquest or implementing proper input sanitization techniques that prevent SQL injection attacks. Organizations should implement proper parameterized queries or prepared statements to eliminate the vulnerability at the source. Additionally, network segmentation, web application firewalls, and regular security audits can provide layered protection against exploitation attempts. The remediation process should also include comprehensive code review to identify similar vulnerabilities within the application codebase and adherence to secure coding practices as outlined in the OWASP Top Ten and NIST cybersecurity guidelines. Regular vulnerability scanning and penetration testing should be implemented to ensure ongoing protection against similar threats in the evolving threat landscape.
