Global variable extraction in bitrix/modules/main/tools.php in Bitrix24 22.0.300 allows unauthenticated remote attackers to (1) enumerate attachments on the server and (2) execute arbitrary JavaScript code in the victim's browser, and possibly execute arbitrary PHP code on the server if the victim has administrator privilege, via overwriting uninitialised variables.

Insufficiently Protected Credentials in the AD/LDAP server settings in 1C-Bitrix Bitrix24 through 22.200.200 allow remote administrators to discover an AD/LDAP administrative password by reading the source code of /bitrix/admin/ldap_server_edit.php.
