CVE-2024-2777 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes/PHPGurukul Online Marriage Registration System, specifically within the /admin/application-bwdates-reports-details.php file. The vulnerability arises from improper sanitization of the 'fromdate' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The injection allows the attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, data modification, or even full compromise of the database server. Although the CVSS score is rated medium (5.3), the vulnerability's nature—SQL Injection—typically poses significant risks, especially if the affected system handles sensitive personal data such as marriage registration records. The vulnerability affects only version 1.0 of the product, and no official patches or fixes have been published yet. Public disclosure of the exploit details increases the risk of exploitation, although no known active exploits have been reported in the wild to date. The vulnerability does not require user interaction but does require low privileges (PR:L), suggesting that some level of authenticated access might be necessary, possibly administrative or semi-privileged access to the admin panel. The lack of scope change (S:U) indicates the impact is confined to the vulnerable component or system. Overall, this vulnerability represents a significant risk to the confidentiality and integrity of the data managed by the Online Marriage Registration System, with potential availability impact if the database is manipulated or corrupted.

For European organizations using the Campcodes Online Marriage Registration System, this vulnerability could lead to severe data breaches involving sensitive personal information such as marriage records, dates, and participant details. Unauthorized access or modification of such data could result in privacy violations, legal liabilities under GDPR, and reputational damage. The integrity of official records could be compromised, undermining trust in civil registration authorities. Additionally, if attackers leverage this vulnerability to escalate privileges or disrupt database operations, it could cause service outages affecting public administration workflows. Given the critical nature of civil registration systems, any disruption or data compromise could have cascading effects on related governmental services, including identity verification and legal documentation processes. The medium CVSS score may underestimate the real-world impact due to the sensitivity of the data involved. European organizations relying on this system must consider the potential for regulatory penalties and the need for incident response readiness.

Implement strict input validation and parameterized queries or prepared statements in the affected /admin/application-bwdates-reports-details.php script to prevent SQL injection. Restrict access to the admin panel and sensitive endpoints by enforcing strong authentication mechanisms and role-based access controls to limit exposure to low-privilege users. Conduct a thorough code audit of all input handling in the Online Marriage Registration System to identify and remediate similar injection flaws. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'fromdate' parameter and other inputs. Monitor database logs and application logs for unusual query patterns or failed injection attempts to detect early exploitation attempts. Isolate the database server from direct internet access and ensure network segmentation to reduce the attack surface. Prepare an incident response plan specific to this vulnerability, including data backup and recovery procedures to mitigate potential data integrity issues. Engage with the vendor or community to obtain or develop patches, and apply them promptly once available. Educate administrative users on the risks of SQL injection and the importance of secure credential management to prevent unauthorized access.
