Description

MiCode FileExplorer contains an authentication bypass vulnerability in the embedded SwiFTP FTP server component that allows network attackers to log in without valid credentials. Attackers can send arbitrary username and password combinations to the PASS command handler, which unconditionally grants access and allows listing, reading, writing, and deleting files exposed by the FTP server. The MiCode/Explorer open source project has reached end-of-life status.
