CVE-2024-48744 identifies a reflected Cross Site Scripting (XSS) vulnerability in the PHPGurukul Teachers Record Management System version 2.1, located in the /trms/listed-teachers.php page. The vulnerability arises because the 'searchinput' POST parameter is not properly sanitized or encoded before being reflected in the server's response. This flaw enables remote attackers to inject and execute arbitrary JavaScript code in the context of the victim's browser when they interact with the vulnerable endpoint. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as clicking a crafted link or submitting a malicious form. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component, potentially impacting the confidentiality and integrity of user data. The CVSS 3.1 base score of 6.1 reflects a medium severity level, indicating a moderate risk. Although no public exploits have been reported yet, the vulnerability could be leveraged for session hijacking, phishing, or delivering further malware payloads. The CWE-94 tag appears to be a misclassification since CWE-94 refers to code injection, but this is a reflected XSS issue typically associated with CWE-79. The lack of available patches or mitigations at the time of publication increases the urgency for organizations to implement compensating controls.

The primary impact of this vulnerability is on the confidentiality and integrity of user sessions and data within the affected Teachers Record Management System. Exploitation allows attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, theft of sensitive information such as credentials or personal data, and manipulation of displayed content. While availability is not directly impacted, successful exploitation can facilitate further attacks that degrade system trustworthiness and user confidence. Educational institutions and organizations relying on PHPGurukul TRMS may face reputational damage, regulatory compliance issues, and operational disruptions if attackers leverage this vulnerability. The medium CVSS score indicates moderate risk, but the real-world impact depends on the deployment scale and user base exposure. Since no authentication is required, any user who interacts with a maliciously crafted request is at risk, broadening the attack surface.

To mitigate CVE-2024-48744, organizations should immediately implement strict input validation and output encoding on the 'searchinput' parameter within /trms/listed-teachers.php. Employ context-aware encoding (e.g., HTML entity encoding) to neutralize injected scripts before rendering user input in responses. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Additionally, implement HTTPOnly and Secure flags on session cookies to reduce session hijacking risks. Conduct thorough code reviews and penetration testing focused on XSS vectors in the application. If possible, isolate the vulnerable component behind a web application firewall (WAF) with rules to detect and block reflected XSS payloads. Educate users about the risks of clicking suspicious links or submitting untrusted forms. Monitor logs for unusual request patterns targeting the 'searchinput' parameter. Finally, coordinate with PHPGurukul developers or vendors to obtain official patches or updates once available.
