Description Adam Mariš 2016-07-25 09:12:27 UTC
Apache POI's XLSX2CSV example uses Java's XML components to parse OpenXML files. Applications and users that use XLSX2CSV and accept such files from end-users are vulnerable to XML External Entity (XXE) attacks, which allow remote attackers to bypass security restrictions and read arbitrary files via a crafted OpenXML document that provides an XML external entity declaration in conjunction with an entity reference.

Affected versions: POI 3.5-3.13
