CVE-2024-53523 is a directory traversal vulnerability identified in the JSFinder project's find_by_file function. Directory traversal (CWE-22) occurs when an application improperly sanitizes user-supplied input, allowing attackers to navigate outside the intended directory structure. In this case, the vulnerability enables remote attackers to craft malicious file path inputs that bypass normal restrictions, thereby accessing arbitrary files on the server. The CVSS 3.1 base score of 7.5 reflects a high severity due to the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (C:H), with no integrity or availability effects. Although the affected versions are not specified, the vulnerability is confirmed in a specific commit (d70ab9bc5221e016c08cffaf0d9ac79646c90645). No patches or known exploits are currently available, indicating the vulnerability is newly disclosed. The lack of authentication and user interaction requirements makes exploitation straightforward if the vulnerable JSFinder instance is accessible over the network. This vulnerability could expose sensitive configuration files, credentials, or other critical data stored on the server, posing a significant risk to organizations relying on JSFinder for file searching or management.

The primary impact of CVE-2024-53523 is the unauthorized disclosure of sensitive information due to directory traversal. Attackers can read arbitrary files, potentially exposing credentials, configuration files, or proprietary data. This breach of confidentiality can lead to further attacks such as privilege escalation, lateral movement, or targeted exploitation based on the exposed information. Since the vulnerability does not affect integrity or availability, it does not directly enable data modification or service disruption. However, the exposure of sensitive files can indirectly facilitate more severe attacks. Organizations worldwide using JSFinder in their infrastructure or development environments face increased risk of data leakage. The ease of exploitation and lack of authentication requirements amplify the threat, especially for publicly accessible instances. The absence of known exploits currently provides a window for proactive mitigation, but the vulnerability's disclosure may soon lead to active exploitation attempts.

To mitigate CVE-2024-53523, organizations should first identify all instances of JSFinder in their environment and assess exposure. Since no official patches are currently available, immediate mitigation involves implementing strict input validation and sanitization on the find_by_file function to prevent directory traversal sequences such as '../'. Employing whitelisting of allowed file paths or restricting file access to predefined directories can reduce risk. Network-level controls such as firewall rules or access control lists should limit external access to JSFinder services. Monitoring logs for suspicious file path requests can help detect exploitation attempts early. Organizations should also track updates from the JSFinder project for official patches and apply them promptly once released. In development or testing environments, consider disabling or restricting JSFinder functionality until the vulnerability is resolved. Additionally, educating developers and administrators about secure coding practices related to file path handling can prevent similar issues in the future.
