CVE-2025-45009 is a medium-severity HTML Injection vulnerability identified in the normal-search.php file of the PHPGurukul Park Ticketing Management System version 2.0. The vulnerability arises from improper sanitization or validation of the 'searchdata' parameter, which is used in the search functionality of the application. An attacker with low privileges (requiring some level of authentication) can remotely supply crafted input to the 'searchdata' parameter, leading to injection of arbitrary HTML content. This can result in arbitrary code execution within the context of the affected web application, potentially enabling cross-site scripting (XSS)-like attacks or manipulation of the application's behavior. The CVSS 3.1 base score is 5.3, reflecting a medium impact with low attack complexity and no user interaction required. The vulnerability affects confidentiality, integrity, and availability to a limited extent, as the attacker can inject code that may steal session tokens, deface content, or disrupt service. The weakness is categorized under CWE-77 (Improper Neutralization of Special Elements used in a Command), indicating that the input is not properly sanitized before being processed. No public exploits or patches are currently available, and the vulnerability was published on April 30, 2025. The attack vector is local network (AV:L), meaning the attacker must have access to the local network or authenticated access to the system, which limits the scope of exploitation but still poses a risk to internal users or compromised accounts.

For European organizations using the PHPGurukul Park Ticketing Management System v2.0, this vulnerability could lead to unauthorized code execution within the application context, potentially compromising user data confidentiality and application integrity. Given that ticketing systems often handle personal data and payment information, exploitation could facilitate data leakage, session hijacking, or fraudulent transactions. The availability impact, while rated low to medium, could disrupt ticketing operations, leading to service downtime and reputational damage. Organizations in the tourism, event management, and public venue sectors are particularly at risk. Since the attack requires local network access and some level of authentication, insider threats or compromised credentials could be leveraged to exploit this vulnerability. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability becomes widely known.

Implement strict input validation and sanitization on the 'searchdata' parameter to neutralize any HTML or script elements before processing or rendering. Apply web application firewall (WAF) rules specifically targeting injection patterns related to the 'searchdata' parameter to detect and block malicious payloads. Restrict access to the ticketing management system to trusted internal networks and enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of unauthorized access. Conduct regular code reviews and security testing focusing on input handling in all user-facing parameters, especially those involved in search or query functionalities. Monitor application logs for unusual or suspicious input patterns targeting the search functionality to detect potential exploitation attempts early. Engage with the vendor or development team to obtain or develop patches addressing this vulnerability, and prioritize timely deployment once available.
