CVE-2021-44138 is a directory traversal vulnerability affecting Caucho Resin versions 4.0.52 through 4.0.56. This flaw allows remote, unauthenticated attackers to read arbitrary files on the server by injecting a semicolon (;) into a pathname within an HTTP request. With a CVSS score of 7.5 (HIGH), this vulnerability is easily exploitable over the network with no user interaction, leading to high confidentiality impact. While there is no evidence of active exploitation or Metasploit modules, Nuclei templates exist, and its high EPSS score suggests a significant likelihood of future exploitation.
