CVE-2025-45011 is a medium-severity HTML Injection vulnerability identified in the foreigner-search.php file of the PHPGurukul Park Ticketing Management System version 2.0. This vulnerability arises from improper sanitization or validation of the 'searchdata' POST request parameter, which allows remote attackers with limited privileges to inject arbitrary HTML or script code. The injection occurs due to the system's failure to correctly handle user-supplied input before rendering it in the web interface, leading to potential execution of malicious code in the context of the victim's browser. The vulnerability is classified under CWE-77 (Command Injection), indicating that the injected content could be interpreted as commands or scripts. The CVSS 3.1 base score is 5.3, reflecting a medium impact with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L. This means the attack requires local access with low complexity and low privileges, no user interaction, and impacts confidentiality, integrity, and availability to a limited extent. Although no known exploits are currently reported in the wild, the vulnerability could be leveraged by attackers who have some level of access to the system to execute arbitrary code, potentially leading to unauthorized actions or data exposure within the ticketing system environment. The lack of vendor or product-specific details limits the scope of direct attribution, but the vulnerability is specific to the PHPGurukul Park Ticketing Management System v2.0, a niche application likely used in park or event management contexts.

For European organizations, particularly those involved in event management, tourism, or public venue operations using the PHPGurukul Park Ticketing Management System, this vulnerability poses a moderate risk. Exploitation could allow attackers with limited local access to execute arbitrary code, potentially leading to unauthorized data access, manipulation of ticketing records, or disruption of service availability. This could result in financial losses, reputational damage, and operational interruptions. Given the nature of the vulnerability, attackers might escalate privileges or move laterally within the network if additional vulnerabilities exist. The impact on confidentiality is limited but non-negligible, as sensitive customer or operational data could be exposed or altered. Integrity and availability impacts are also present but limited in scope. Since the vulnerability requires local access and low privileges, the risk is higher in environments where multiple users have access to the system or where the system is not adequately segmented. European organizations with integrated ticketing systems in public venues or parks should be aware of this threat, especially if they rely on PHPGurukul solutions or similar platforms.

To mitigate CVE-2025-45011, organizations should implement the following specific measures: 1) Apply input validation and sanitization rigorously on the 'searchdata' POST parameter to neutralize any HTML or script content before processing or rendering. Use established libraries or frameworks that provide robust escaping functions for HTML contexts. 2) Restrict access to the ticketing management system to trusted users only, enforcing strict access controls and network segmentation to minimize the risk of local exploitation. 3) Monitor and audit user activities on the system to detect any anomalous behavior indicative of exploitation attempts. 4) If possible, upgrade or patch the PHPGurukul Park Ticketing Management System to a version where this vulnerability is addressed; if no patch is available, consider deploying web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'searchdata' parameter. 5) Conduct security training for administrators and users to recognize suspicious activities and maintain good security hygiene. 6) Implement Content Security Policy (CSP) headers to reduce the impact of potential HTML injection by restricting the execution of unauthorized scripts. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and operational context.
