CVE-2024-39090 identifies a security vulnerability in the PHPGurukul Online Shopping Portal Project version 2.0, where a Cross-Site Request Forgery (CSRF) vulnerability leads to Stored Cross-Site Scripting (XSS). The CSRF flaw allows an attacker to trick an authenticated user into submitting a malicious request unknowingly. This request can inject persistent malicious JavaScript code into the application’s data store, which is then executed in the context of other users’ browsers when they access the affected pages. The exploitation does not require prior authentication but does require the victim to interact with a crafted link or page. The vulnerability impacts confidentiality and integrity by enabling attackers to hijack user sessions, steal sensitive information, or perform unauthorized actions on behalf of the user. The CVSS 3.1 base score of 6.1 reflects a medium severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and a scope change indicating that the vulnerability affects resources beyond the initially vulnerable component. No patches or known exploits have been reported yet, but the risk remains significant due to the potential for account takeover and data theft. The vulnerability is classified under CWE-352 (Cross-Site Request Forgery).

The primary impact of CVE-2024-39090 is the potential for attackers to hijack user sessions and perform unauthorized actions within the PHPGurukul Online Shopping Portal. This can lead to account takeover, unauthorized purchases, theft of personal and payment information, and reputational damage to affected organizations. Since the vulnerability allows stored XSS, it can also facilitate further attacks such as cookie theft, keylogging, or spreading malware to other users. The compromise of user accounts can have cascading effects, including financial loss and erosion of customer trust. Organizations relying on this software for e-commerce operations face risks to their business continuity and compliance with data protection regulations. Although no known exploits are currently active, the ease of exploitation via social engineering and the widespread use of online shopping portals increase the threat potential globally.

To mitigate CVE-2024-39090, organizations should implement robust anti-CSRF protections such as synchronizer tokens or double-submit cookies to ensure that state-changing requests are legitimate. Input validation and output encoding must be enforced rigorously to prevent injection of malicious scripts into stored data. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit and sanitize user-generated content before storage and display. Educate users about the risks of clicking on suspicious links and encourage the use of updated browsers with security features. Monitor logs for unusual activities indicative of CSRF or XSS exploitation attempts. Since no official patch is currently available, consider temporary workarounds such as disabling vulnerable features or restricting access to trusted users until a fix is released. Engage with the software vendor or community to track patch availability and apply updates promptly.
