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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":12,"ransomware":0},"changes":[{"seq":207509,"id":"CVE-2017-20284","ts":1789764764712,"field":"exploit_available","old":"false","new":"true"}]}
