CVE-2022-23612: Directory Traversal in OpenMRS Startup Filter

Noroxi assessment

Priority: Monitor (action score 31/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 80% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
