A vulnerability in Veeam Backup & Replication platform allows a low-privileged user with a specific role to exploit a method that updates critical configuration settings, such as modifying the trusted client certificate used for authentication on a specific port. This can result in unauthorized access, enabling the user to call privileged methods and initiate critical services. The issue arises due to insufficient permission requirements on the method, allowing users with low privileges to perform actions that should require higher-level permissions.Show less

A vulnerability in Veeam Backup & Replication allows a low-privileged user to connect to remoting services and exploit insecure deserialization by sending a serialized temporary file collection. This exploit allows the attacker to delete any file on the system with service account privileges.

A vulnerability in Veeam Backup & Replication allows a low-privileged user with certain roles to perform remote code execution (RCE) by updating existing jobs. These jobs can be configured to run pre- and post-scripts, which can be located on a network share and are executed with elevated privileges by default. The user can update a job and schedule it to run almost immediately, allowing arbitrary code execution on the server.Show less

Synapse is an open-source Matrix homeserver. Synapse before version 1.106 allows, by design, unauthenticated remote participants to trigger a download and caching of remote media from a remote homeserver to the local media repository. Such content then also becomes available for download from the local homeserver in an unauthenticated way. The implication is that unauthenticated remote adversaries can use this functionality to plant problematic content into the media repository. Synapse 1.106 introduces a partial mitigation in the form of new endpoints which require authentication for media downloads. The unauthenticated endpoints will be frozen in a future release, closing the attack vector.Show less

Multiple FCNT Android devices provide the original security features such as "privacy mode" where arbitrary applications can be set not to be displayed, etc. Under certain conditions, and when an attacker can directly operate the device which its screen is unlocked by a user, the provided security features' setting pages may be exposed and/or the settings may be altered, without authentication. For example, specific applications in the device configured to be hidden may be displayed and/or activated.Show less
