A vulnerability classified as critical has been found in openviglet shio up to 0.3.8. Affected is the function shStaticFileUpload of the file shio-app/src/main/java/com/viglet/shio/api/staticfile/ShStaticFileAPI.java. The manipulation of the argument filename leads to unrestricted upload. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
Unrestricted file upload in OpenViglet Shio through version 0.3.8 allows authenticated remote attackers to upload arbitrary files via manipulation of the filename parameter in the ShStaticFileAPI.shStaticFileUpload function. The vulnerability requires valid authentication credentials but lacks proper input validation on uploaded filenames, enabling arbitrary file placement on the server. Publicly available exploit code exists, though EPSS score remains low at 0.11% (28th percentile), suggesting limited real-world exploitation despite public disclosure.
