Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2022-23612

High
7.5/10

Summary

OpenMRS is a patient-based medical record system focusing on giving providers a free customizable electronic medical record system. Affected versions are subject to arbitrary file exfiltration due to failure to sanitize request when satisfying GET requests for `/images` & `/initfilter/scripts`. This can allow an attacker to access any file on a system running OpenMRS that is accessible to the user id OpenMRS is running under. Affected implementations should update to the latest patch version of OpenMRS Core for the minor version they use. These are: 2.1.5, 2.2.1, 2.3.5, 2.4.5 and 2.5.3. As a general rule, this vulnerability is already mitigated by Tomcat's URL normalization in Tomcat 7.0.28+. Users on older versions of Tomcat should consider upgrading their Tomcat instance as well as their OpenMRS instance.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
