The CVE-2024-2723 vulnerability represents a critical sql injection flaw within the cigesv2 system that specifically targets the /ajaxSubServicios.php endpoint. This vulnerability manifests through the 'idservicio' parameter which fails to properly validate or sanitize user input before incorporating it into database queries. The flaw exists in the application's input handling mechanisms where maliciously crafted sql payloads can be directly executed against the underlying database system. The vulnerability is classified under cwe-89 sql injection, which is a well-documented weakness that allows attackers to manipulate database queries through untrusted input. This particular implementation represents a classic case of improper input validation where the application does not employ adequate sanitization or parameterization techniques to prevent malicious sql code execution.
The operational impact of this vulnerability extends far beyond simple data retrieval as it provides attackers with complete database access capabilities. A remote threat actor can exploit this weakness to execute arbitrary sql commands against the database, potentially leading to data exfiltration, data modification, or even complete system compromise. The vulnerability allows for blind sql injection techniques where attackers can infer database structure and content through response variations, making it particularly dangerous for applications handling sensitive information. This type of vulnerability is particularly concerning in web applications that process user input directly into database queries without proper security controls, creating a direct pathway for unauthorized database access. The attack surface is amplified by the fact that this vulnerability is accessible through a simple http request to the ajax endpoint, making it easily exploitable by automated scanning tools and script kiddies.
The exploitation of this vulnerability follows established patterns documented in the mitre att&ck framework under the technique of command and control through sql injection. Attackers can leverage this weakness to perform data extraction, privilege escalation, and potentially establish persistent access through database backdoors. The specific nature of the vulnerability allows for union-based sql injection attacks where attackers can append malicious sql payloads to the idservicio parameter to retrieve information from other database tables. Organizations running this system face significant risk of data breaches, regulatory violations, and financial losses. The vulnerability's presence in a web service endpoint indicates poor security practices in input handling and database access control, representing a fundamental failure in application security design. This flaw aligns with the broader category of insecure data handling practices that are commonly exploited in web application attacks, particularly in systems that lack proper parameterized query implementation or input validation controls.
Mitigation strategies for CVE-2024-2723 should focus on implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations must immediately implement prepared statements or parameterized queries for all database interactions, particularly for the idservicio parameter in the ajaxSubServicios.php endpoint. The application should employ input sanitization techniques that strip or escape potentially malicious sql characters and patterns. Additionally, implementing proper access controls and least privilege principles for database connections can limit the damage from successful exploitation attempts. Security monitoring should be enhanced to detect unusual database access patterns that might indicate sql injection attempts. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components. The implementation of web application firewalls and sql injection detection systems can provide additional layers of protection against this class of attacks. Organizations should also establish proper incident response procedures to address potential exploitation attempts and ensure rapid remediation of identified vulnerabilities.
