CVE-2024-42762 identifies a stored Cross Site Scripting (XSS) vulnerability in the Kashipara Bus Ticket Reservation System version 1.0, located in the /history.php endpoint. Stored XSS occurs when malicious input is saved on the server and later rendered in web pages without proper sanitization, allowing attackers to execute arbitrary JavaScript code in the context of other users' browsers. In this case, the vulnerability arises from insufficient input validation or output encoding of the Name, Phone, and Email parameters, which are stored and subsequently displayed. An attacker can craft payloads that, when viewed by legitimate users, execute scripts that may hijack sessions, deface content, or redirect users to malicious sites. The CVSS 3.1 score of 5.4 (medium) reflects that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. Confidentiality and integrity impacts are low, while availability is unaffected. No patches or known exploits have been reported as of the publication date, suggesting the vulnerability is newly disclosed. The vulnerability is categorized under CWE-79, which is the standard classification for XSS issues. Given the nature of the system—a bus ticket reservation platform—this vulnerability could be exploited to target customers and administrative users alike, potentially leading to session hijacking or phishing attacks within the application environment.

The primary impact of CVE-2024-42762 is the compromise of user confidentiality and integrity within the Kashipara Bus Ticket Reservation System. Attackers exploiting this stored XSS vulnerability can execute arbitrary scripts in the browsers of users who view the affected pages, enabling theft of session cookies, credentials, or other sensitive information. This can lead to unauthorized actions performed on behalf of legitimate users, including ticket purchases or data manipulation. While availability is not directly impacted, the trustworthiness of the system is undermined, potentially damaging the reputation of service providers. Organizations relying on this system may face increased risk of targeted phishing campaigns or broader attacks if attackers leverage the vulnerability to pivot within the network. The requirement for some privileges and user interaction limits the ease of exploitation but does not eliminate risk, especially in environments where users have elevated permissions or where social engineering is effective. The lack of patches increases exposure until mitigations are applied. Overall, the vulnerability poses a moderate risk to organizations handling customer data and transactional operations through this platform.

To mitigate CVE-2024-42762, organizations should implement strict input validation and output encoding on all user-supplied data fields, particularly Name, Phone, and Email parameters in the /history.php page. Employ context-aware encoding (e.g., HTML entity encoding) before rendering data in the browser to prevent script execution. Use security headers such as Content Security Policy (CSP) to restrict the execution of unauthorized scripts. Conduct thorough code reviews and penetration testing focused on XSS vectors within the application. If possible, isolate or sandbox the affected components to limit the scope of impact. Educate users and administrators about the risks of clicking suspicious links or interacting with untrusted content. Monitor logs for unusual activity that may indicate exploitation attempts. Since no official patches are available, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting these parameters. Finally, maintain an incident response plan to quickly address any exploitation events.
