CVE-2024-24134 is a medium-severity Cross Site Scripting (XSS) vulnerability found in Sourcecodester Online Food Menu version 1.0. The vulnerability arises from insufficient input sanitization in the 'Menu Name' and 'Description' fields within the Update Menu section of the application. An attacker with authenticated access and the ability to interact with the user interface can inject malicious scripts into these fields. Due to the vulnerability's reflected or stored XSS nature (not explicitly stated but implied by the fields involved), the injected scripts may execute in the context of other users viewing the affected menu entries, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The CVSS 3.1 vector indicates that the attack requires network access (AV:N), low attack complexity (AC:L), but requires privileges (PR:H) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact affects confidentiality and integrity with no impact on availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is classified under CWE-79, which is the standard classification for Cross Site Scripting issues.

For European organizations using Sourcecodester Online Food Menu 1.0, this vulnerability could lead to unauthorized disclosure of sensitive information such as session tokens or user credentials, enabling attackers to impersonate legitimate users. This can result in data breaches, unauthorized modifications to menu data, or further pivoting within the organization's network. Given that the vulnerability requires authenticated access and user interaction, the risk is somewhat mitigated but remains significant in environments where multiple users have update privileges or where social engineering can be leveraged. The compromise of web applications handling customer-facing menus could also damage brand reputation and customer trust, especially in the hospitality and food service sectors prevalent across Europe. Additionally, the changed scope of the vulnerability suggests that exploitation could affect other components or users beyond the initially targeted menu update function, increasing the potential impact.

European organizations should implement strict input validation and output encoding on the 'Menu Name' and 'Description' fields to neutralize malicious scripts. Employing a web application firewall (WAF) with rules targeting XSS payloads can provide an additional layer of defense. Since no official patches are currently available, organizations should consider restricting update menu privileges to trusted users only and monitor logs for suspicious activities related to menu updates. Conducting regular security assessments and penetration testing focusing on input fields can help identify similar vulnerabilities. Additionally, educating users about the risks of clicking on suspicious links or interacting with untrusted content can reduce the risk of exploitation via social engineering. Organizations should also stay alert for any forthcoming patches or updates from the vendor or community and apply them promptly once released.
