CVE-2024-46300 identifies a Cross Site Scripting (XSS) vulnerability in the itsourcecode Placement Management System version 1.0. The flaw exists in the Full Name field of the registration.php page, where user input is not properly sanitized or encoded before being reflected back to the user. This improper handling allows attackers to inject malicious JavaScript code that executes in the context of other users' browsers when they view the affected page or data. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The CVSS 3.1 base score of 6.1 indicates a medium severity, with the vector string AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N meaning the attack can be performed remotely over the network without privileges, requires low attack complexity, no privileges, but does require user interaction. The scope is changed (S:C) indicating that the vulnerability affects resources beyond the vulnerable component, potentially impacting user sessions or other components. The impact on confidentiality and integrity is low but non-negligible, as attackers can steal cookies, hijack sessions, or manipulate displayed content. No patches or known exploits are currently available, but the vulnerability should be addressed promptly to prevent future exploitation.

The primary impact of CVE-2024-46300 is the potential compromise of user confidentiality and integrity through the execution of malicious scripts in victim browsers. This can lead to session hijacking, theft of sensitive information such as cookies or credentials, and manipulation of web content to mislead users or perform phishing attacks. While availability is not directly affected, the trustworthiness of the Placement Management System is undermined, potentially disrupting user operations and damaging organizational reputation. Organizations relying on this system for managing placements, student data, or recruitment processes may face data breaches or unauthorized access incidents. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where users may be tricked into clicking malicious links or submitting crafted input. The lack of known exploits currently reduces immediate risk but also means attackers may develop exploits in the future if the vulnerability remains unpatched.

To mitigate CVE-2024-46300, organizations should implement strict input validation and output encoding on the Full Name field and any other user-supplied inputs. Specifically, employ context-aware encoding (e.g., HTML entity encoding) before reflecting user input in web pages to prevent script execution. Use security libraries or frameworks that automatically handle XSS protection. Additionally, implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly update and patch the Placement Management System once vendor fixes become available. Conduct security testing, including automated scanning and manual code reviews, focusing on input handling and output rendering. Educate users about the risks of clicking unknown links or submitting untrusted data. Finally, consider deploying Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting the affected endpoints.
