CVE-2026-40075— OpenMRS Core arbitrary file read via path traversal in ModuleResourcesServlet

OpenMRS Core arbitrary file read via path traversal in ModuleResourcesServlet

OpenMRS Core is an open source electronic medical record system platform. In versions 2.7.8 and earlier and versions 2.8.0 through 2.8.5, the `/openmrs/moduleResources/{moduleid}` endpoint is vulnerable to a path traversal attack. The ModuleResourcesServlet constructs a filesystem path from user-controlled input without performing path boundary validation — the getFile() method concatenates the user-supplied path into an absolute filesystem path without calling normalize() or checking that the result stays within the allowed module resources directory. Because this endpoint serves static resources required for rendering the login page, it is not protected by authentication filters, allowing unauthenticated exploitation. An attacker can traverse directories and read arbitrary files from the server filesystem, including /etc/passwd and application configuration files containing database credentials. Successful exploitation requires the target deployment to run on Apache Tomcat versions prior to 8.5.31, where the ..; path parameter bypass is not mitigated by the container. Deployments on Tomcat 8.5.31 or later and Tomcat 9.0.10 or later are protected at the container level, though the underlying code defect remains. This issue has been fixed in versions after 2.7.8 (within the 2.7.x branch) and in version 2.8.6 and later.

对路径名的限制不恰当(路径遍历)

openmrs-core 路径遍历漏洞

openmrs-core是OpenMRS开源的一款电子病历系统。 openmrs-core存在路径遍历漏洞，该漏洞源于ModuleResourcesServlet的getFile方法未进行路径边界验证，可能导致未经身份验证的攻击者遍历目录并读取任意文件。以下版本受到影响：2.7.8及之前版本和2.8.0版本至2.8.5版本。
