GHSA-fp4f-xmw6-5jf8: GRR vulnerable to Remote Code Execution Via PHP Code Injection

GRR is a resource management and reservation application. Prior to the advisory-reported fixed version 4.5.0, an administrator can inject malicious PHP through LDAP connector configuration parameters such as ldapfilter, poisoning /personnalisation/configldap.inc.php and permitting remote code execution. The administrator must first successfully connect to an LDAP server, which can be attacker-controlled, and then submit malicious input on the subsequent connector settings page. The advisory reports this issue as fixed in version 4.5.0.
