Caucho Resin's documentation web application (resin-doc) is vulnerable to a path traversal flaw that permits unauthenticated remote attackers to access arbitrary files on the server by manipulating the inputFile parameter in the jndi-appconfig tutorial servlet. This vulnerability could lead to unauthorized disclosure of sensitive information stored on the system. Organizations using Caucho Resin should prioritize remediation to mitigate the risk of data exposure.

Original NVD Description

Caucho Resin contains a path traversal vulnerability in the documentation webapp (resin-doc) that allows remote unauthenticated attackers to read arbitrary files by supplying a relative path through the inputFile request parameter of the jndi-appconfig tutorial servlet. Attackers can craft requests with directory traversal sequences to the servlet endpoint to read files outside the intended tutorial directory on the underlying system. Exploitation evidence was first observed by the Shadowserver Foundation on 2021-12-10.
