CVE-2022-23612

Exploit

Directory Traversal in OpenMRS Startup Filter

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

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
