Apache Sling Commons Messaging Mail 2.0 adds support for enabling server identity checks and these checks are enabled by default.

A user could enable these checks nevertheless by accessing the session via the message created by SimpleMessageBuilder and setting the property to true. The SimpleMailService in Apache Sling Commons Messaging Mail 1.0 lacks an option to enable these checks for the shared mail session. For compatibility reasons these additional checks are disabled by default in JavaMail/Jakarta Mail. To reduce the risk of 'man in the middle' attacks additional server identity checks must be performed when accessing mail servers. In case the tenant has an smtp credential set, the full credential information is disclosed.Īpache Sling Commons Messaging Mail provides a simple layer on top of JavaMail/Jakarta Mail for OSGi to send mails via SMTPS. The correct exploitation of this vulnerability causes sensitive information exposure. The vulnerability allows an unauthenticated attacker to use an api endpoint to generate a temporary JWT token that is designed to reference the correct tenant prior to authentication, to request system configuration parameters using direct api requests. A broken access control vulnerability has been found while using a temporary generated token in order to consume api resources. The Systeam application is an ERP system that uses a mixed architecture based on SaaS tenant and user management, and on-premise database and web application counterparts. It is also the basis for MDaemon Tech's Security Gateway for Email Servers.Īccording to 's Mail (MX) Server Survey from May 2020, MDaemon provides approximately 7.6‰ of all known Internet mail servers, the fifth largest installation base from all identified servers.Dalmark Systems Systeam 2.22.8 build 1724 is vulnerable to Incorrect Access Control.
