CVE-2025-65354 is a high-severity SQL injection vulnerability identified in the event-management 1.0 software developed by PuneethReddyHC. The vulnerability exists in the /Grocery/search_products_itname.php script, where the sitem_name POST parameter is not properly sanitized or validated before being incorporated into SQL queries. This improper input handling allows an attacker to inject malicious SQL code that can alter the intended query logic. By exploiting this flaw, an attacker can retrieve unauthorized data from the backend database, including sensitive customer or event information, or potentially execute further commands that compromise the backend system. The vulnerability is exploitable remotely without requiring authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score of 9.8 reflects the critical impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. Although no patches or known exploits have been reported yet, the vulnerability's nature and severity demand immediate attention. The affected software version is event-management 1.0, but no detailed version range is provided. The lack of patch links suggests that a fix may not yet be available, emphasizing the need for defensive measures. This vulnerability could be leveraged by attackers to conduct data exfiltration, disrupt event management operations, or gain persistent backend access.

For European organizations, exploitation of CVE-2025-65354 could lead to significant data breaches involving sensitive customer and event data, undermining privacy compliance obligations such as GDPR. The unauthorized disclosure of database contents can damage organizational reputation and result in regulatory penalties. Additionally, backend compromise may allow attackers to manipulate event management processes, disrupt services, or use the compromised system as a foothold for lateral movement within the network. Organizations in sectors heavily reliant on event management software, such as retail, hospitality, and entertainment, face operational risks and potential financial losses. The critical severity and remote exploitability mean that even organizations with limited security controls could be targeted. The absence of authentication requirements broadens the attack surface, increasing the likelihood of automated exploitation attempts. Overall, this vulnerability threatens confidentiality, integrity, and availability, with potential cascading effects on business continuity and compliance.

European organizations should immediately audit their use of the event-management 1.0 software to determine exposure to the vulnerable /Grocery/search_products_itname.php endpoint. In the absence of an official patch, organizations should implement the following mitigations: 1) Apply Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the sitem_name parameter, including common SQL injection payload patterns. 2) Conduct input validation and sanitization at the application layer, ensuring that POST parameters are strictly validated against expected formats and reject suspicious input. 3) Employ parameterized queries or prepared statements in the backend code to prevent SQL injection, if source code access and modification are possible. 4) Monitor logs for unusual query patterns or error messages indicative of injection attempts. 5) Restrict database user privileges associated with the application to the minimum necessary, limiting the impact of a successful injection. 6) Consider network segmentation to isolate the event management system from critical infrastructure. 7) Stay alert for vendor updates or patches and apply them promptly once available. 8) Conduct penetration testing to verify the effectiveness of mitigations and identify residual risks.
