CVE-2025-48323 is a medium-severity vulnerability classified under CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the 'Advance Food Menu' product developed by Md Abunaser Khan, up to version 1.0. The vulnerability is a Stored XSS flaw, meaning that malicious scripts injected by an attacker are stored on the target server and subsequently served to users without proper sanitization or encoding. This allows an attacker to execute arbitrary JavaScript in the context of the victim's browser when they access the affected web pages. The CVSS v3.1 base score is 5.9, indicating a medium severity level. The vector string (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) shows that the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, reflecting that the attacker can potentially steal limited data, modify some content, or cause partial disruption. No patches or known exploits in the wild have been reported as of the publication date (August 28, 2025). The vulnerability arises from insufficient input validation or output encoding during web page generation, allowing malicious payloads to be stored and executed in users' browsers.

For European organizations using the Advance Food Menu software, this vulnerability poses a risk of client-side attacks that could lead to session hijacking, theft of sensitive user information, or unauthorized actions performed on behalf of legitimate users. Although the impact on confidentiality, integrity, and availability is rated low to medium, the stored nature of the XSS increases the risk since malicious scripts persist and affect multiple users over time. This can damage organizational reputation, lead to regulatory non-compliance (especially under GDPR if personal data is compromised), and potentially facilitate further attacks such as phishing or malware distribution. The requirement for high privileges to exploit somewhat limits the attack surface but does not eliminate risk, especially in environments where internal users or administrators might be targeted. The need for user interaction means social engineering could be used to trigger the exploit. Given the widespread use of web-based menu management systems in hospitality and food service sectors across Europe, organizations in these industries could face operational disruptions and customer trust issues if exploited.

1. Immediate mitigation should include implementing strict input validation and output encoding on all user-supplied data fields within the Advance Food Menu application to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Restrict privileges and access controls to minimize the number of users who can input or modify menu data, reducing the risk of high-privilege exploitation. 4. Conduct regular security audits and code reviews focusing on input handling and sanitization. 5. Educate users and administrators about the risks of social engineering and encourage cautious behavior when interacting with the application. 6. Monitor web application logs for unusual input patterns or script injections. 7. Since no official patch is currently available, consider isolating or temporarily disabling vulnerable components until a vendor patch or update is released. 8. If feasible, deploy Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting the application. 9. Maintain up-to-date backups and incident response plans to quickly recover from any successful exploitation.
