In GLPI before version 9.5.2, the ​pluginimage.send.php​ endpoint allows a user to specify an image from a plugin. The parameters can be maliciously crafted to instead delete the .htaccess file for the files directory. Any user becomes able to read all the files and folders contained in “/files/”. Some of the sensitive information that is compromised are the user sessions, logs, and more. An attacker would be able to get the Administrators session token and use that to authenticate. The issue is patched in version 9.5.2.

Weakness

The product makes files or directories accessible to unauthorized actors, even though they should not be.

Glpi Glpi-project * 9.5.2 (excluding)

Extended Description

Web servers, FTP servers, and similar servers may store a set of files underneath a “root” directory that is accessible to the server’s users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
