Description

NVD

The File Manager (wp-file-manager) plugin before 6.9 for WordPress allows remote attackers to upload and execute arbitrary PHP code because it renames an unsafe example elFinder connector file to have the .php extension. This, for example, allows attackers to run the elFinder upload (or mkfile and put) command to write PHP code into the wp-content/plugins/wp-file-manager/lib/files/ directory. This was exploited in the wild in August and September 2020.

What CISA says to do

Public module

Metasploit lists a public normal-rank module for this CVE: WordPress File Manager Unauthenticated Remote Code Execution (multi/http/wp_file_manager_rce). A module existing is not the same as active exploitation; see metasploit.com.
