CVE-2024-48195 is a Cross Site Scripting (XSS) vulnerability identified in eyouCMS version 1.6.7, a content management system used for website management. The vulnerability arises from improper sanitization of the 'post' parameter, which allows a remote attacker to inject crafted malicious scripts. When a victim user interacts with the vulnerable parameter, the injected script executes in their browser context, enabling the attacker to steal sensitive information such as session cookies, authentication tokens, or other data accessible via the browser. The vulnerability does not require the attacker to have any privileges or authentication, but it does require user interaction (e.g., clicking a malicious link). The CVSS 3.1 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), with low confidentiality and integrity impact (C:L/I:L) and no availability impact (A:N). No patches or fixes have been published at the time of disclosure, and no known exploits are reported in the wild. The vulnerability is classified under CWE-79, which is a common weakness related to improper neutralization of input during web page generation. This vulnerability can be leveraged to compromise user trust, hijack sessions, or conduct phishing attacks by injecting malicious scripts into web pages served by eyouCMS.

The primary impact of CVE-2024-48195 is on the confidentiality and integrity of user data accessed through eyouCMS-based websites. Attackers can exploit this vulnerability to steal session cookies or other sensitive information, potentially leading to account takeover or unauthorized actions performed on behalf of legitimate users. While availability is not affected, the reputational damage to organizations running vulnerable eyouCMS instances can be significant, especially if customer data is compromised or users are redirected to malicious sites. This vulnerability can also facilitate further attacks such as phishing or malware distribution. Organizations worldwide that rely on eyouCMS for their web presence, particularly those with customer-facing portals or administrative interfaces, face increased risk. The ease of exploitation combined with no authentication requirement makes this vulnerability attractive to attackers targeting web applications with insufficient input validation.

To mitigate CVE-2024-48195, organizations should implement strict input validation and output encoding on all user-supplied data, especially the 'post' parameter in eyouCMS. Employing Content Security Policy (CSP) headers can help reduce the impact of injected scripts by restricting script execution sources. Web application firewalls (WAFs) should be configured to detect and block common XSS attack patterns targeting eyouCMS. Administrators should monitor web logs for suspicious requests containing script tags or unusual payloads. Until an official patch is released, consider disabling or restricting the functionality that processes the vulnerable parameter if feasible. Educating users about the risks of clicking unknown links can reduce the likelihood of successful exploitation. Regularly updating eyouCMS to the latest secure versions once patches are available is critical. Additionally, performing security code reviews and penetration testing focused on input handling can help identify and remediate similar vulnerabilities proactively.
