CVE-2025-45010 is a medium-severity HTML Injection vulnerability identified in the PHPGurukul Park Ticketing Management System version 2.0, specifically within the normal-bwdates-reports-details.php file. The vulnerability arises due to improper sanitization of user-supplied input in the 'fromdate' and 'todate' POST request parameters. An attacker can exploit this flaw by injecting malicious HTML or script code into these parameters, which the application then processes and renders without adequate validation or encoding. This can lead to arbitrary code execution in the context of the affected web application. The vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command), indicating that the injection could potentially allow command or code execution. The CVSS 3.1 base score is 5.3, reflecting a medium severity level, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), low privileges (PR:L), no user interaction (UI:N), and impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the vulnerability poses a risk of unauthorized code execution that could be leveraged for further attacks such as privilege escalation, data tampering, or denial of service. The absence of vendor or product details beyond the PHPGurukul Park Ticketing Management System limits the scope of direct attribution but highlights the need for attention in environments where this system is deployed. No patches or fixes have been published at this time, increasing the urgency for mitigations and monitoring.

For European organizations using the PHPGurukul Park Ticketing Management System v2.0, this vulnerability could lead to unauthorized code execution within their ticketing infrastructure. This may result in data integrity issues, unauthorized access to sensitive ticketing or customer information, and potential service disruptions impacting availability. Given that ticketing systems often interface with payment processing and personal data, exploitation could also have compliance implications under GDPR due to potential data breaches. The medium severity suggests that while the vulnerability is not trivially exploitable remotely, attackers with local access or limited privileges could leverage it to escalate their impact. This could affect organizations managing parks, events, or public venues, potentially leading to reputational damage and operational downtime. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. The vulnerability's impact on confidentiality, integrity, and availability, albeit limited, still warrants proactive risk management in affected environments.

1. Implement strict input validation and sanitization on the 'fromdate' and 'todate' POST parameters to neutralize any injected HTML or script content before processing or rendering. Use established libraries or frameworks that automatically encode output to prevent injection attacks. 2. Apply the principle of least privilege by restricting access to the ticketing management system and its administrative interfaces to trusted users only, minimizing the risk of local exploitation. 3. Monitor logs and network traffic for unusual POST requests targeting the vulnerable parameters, enabling early detection of exploitation attempts. 4. If possible, isolate the ticketing system within a segmented network zone to limit lateral movement in case of compromise. 5. Engage with the PHPGurukul vendor or community to obtain or request a security patch or update addressing this vulnerability. 6. Conduct regular security assessments and penetration tests focusing on input validation and injection vulnerabilities within the ticketing system. 7. Educate system administrators and users about the risks of injection attacks and the importance of reporting suspicious activity promptly.
