CVE-2020-15175
Unauthenticated File Deletion in GLPI
In short
An unauthenticated attacker can delete the .htaccess file in GLPI's files directory, exposing sensitive data like user sessions and logs. This allows them to impersonate administrators and take over the system.
Technical detail
CVE-2020-15175 exploits improper input validation in the pluginimage.send.php endpoint, allowing unauthenticated users to manipulate parameters and delete the .htaccess access control file. This removes directory listing protections, exposing session tokens and sensitive logs that enable privilege escalation and full system compromise.
Summary generated and translated by AI from the official description.
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.
