CVE-2024-26472 is a reflected cross-site scripting (XSS) vulnerability affecting KLiK SocialMediaWebsite version 1.0.1, developed by msaad1999. The vulnerability resides in the 'create-new-pwd.php' page, where the 'selector' and 'validator' parameters are not properly sanitized or encoded before being reflected in the HTTP response. This allows remote attackers to craft malicious URLs containing JavaScript payloads that execute in the context of the victim's browser when they visit the manipulated link. The flaw is categorized under CWE-79, which pertains to improper neutralization of input during web page generation. Exploitation does not require authentication but does require user interaction, such as clicking a malicious link. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability. No patches or known exploits have been reported yet, but the vulnerability poses a risk of session hijacking, credential theft, or other malicious actions via script execution in users' browsers.

The primary impact of this vulnerability is the potential execution of arbitrary JavaScript in the context of the affected web application, which can lead to theft of sensitive information such as session tokens, cookies, or personal data, thereby compromising user confidentiality and integrity. Attackers could also perform actions on behalf of the user, leading to account manipulation or social engineering attacks. Although availability is not affected, the trustworthiness of the platform and user data integrity can be undermined. Organizations running KLiK SocialMediaWebsite may face reputational damage, user data breaches, and potential regulatory consequences if exploited. The requirement for user interaction limits the attack scope but does not eliminate risk, especially in phishing scenarios.

To mitigate this vulnerability, developers should implement strict input validation and context-aware output encoding on the 'selector' and 'validator' parameters to prevent injection of executable scripts. Employing security headers such as Content Security Policy (CSP) can reduce the impact of XSS by restricting script execution sources. Additionally, adopting frameworks or libraries that automatically handle encoding can reduce human error. Regular security testing, including automated scanning and manual code reviews focused on input handling, is recommended. Users should be educated to avoid clicking suspicious links, and multi-factor authentication should be enforced to limit account compromise risks. Since no patches are currently available, organizations should consider temporary workarounds such as disabling or restricting access to the vulnerable page until a fix is released.
