In GLPI before 9.4.6, an attacker can execute system commands by
abusing the backup functionality. Theoretically, this vulnerability
can be exploited by an attacker without a valid account by using a
CSRF. Due to the difficulty of the exploitation, the attack is only
conceivable by an account having Maintenance privileges and the right
to add WIFI networks. This is fixed in version 9.4.6.");
