Overview
org.apache.tomcat.embed:tomcat-embed-core is a Core Tomcat implementation.
Affected versions of this package are vulnerable to Path Equivalence in the doPut() function in DefaultServlet.java, which insecurely replaces path separators with .s.
If the Default Servlet is configured with writes enabled - which it is not by default - a user can exploit Tomcat's partial PUT functionality to achieve code execution via deserialization. The target URL containing sensitive uploaded files must be a sub-directory of a target URL for public uploads, and the malicious user must know the names of the target sensitive files, which are also uploaded using a partial PUT. If both attacker and target application are using the default storage location and it contains a library that deserializes untrusted code, the attacker can trigger the execution of malicious code.
