### Impact Synapse versions before 1.120.1 fail to properly validate invites received over federation. This vulnerability allows a malicious server to send a specially crafted invite that disrupts the invited user's `/sync` functionality. ### Patches Synapse 1.120.1 rejects such invalid invites received over federation and restores the ability to sync for affected users. ### Workarounds Server administrators can disable federation from untrusted servers. ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:[email protected]).

Consumers are getting caught in a web of scams facilitated by online ads often originating from the same perpetrators.

### Impact In Synapse before 1.120.1, `multipart/form-data` requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. ### Patches Synapse 1.120.1 resolves the issue by denying requests with unsupported `multipart/form-data` content type. ### Workarounds Limiting request sizes or blocking the `multipart/form-data` content type before the requests reach Synapse, for example in a reverse proxy, alleviates the issue. Another approach that mitigates the attack is to use a low `max_upload_size` in Synapse. ### References - https://github.com/twisted/twisted/issues/4688#issuecomment-1167705518 - https://github.com/twisted/twisted/issues/4688#issuecomment-2385711609 ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:[email protected]).

A novel backdoor malware and a loader that customizes payload names for each victim have been added to the threat group's cybercriminal tool set.

The Acronis Cyber Protect appliance, in its default configuration, allows the anonymous registration of new protect/backup agents on new endpoints. This API endpoint also generates bearer tokens which the agent then uses to authenticate to the appliance. As the management web console is running on the same port as the API for the agents, this bearer token is also valid for any actions on the web console. This allows an attacker with network access to the appliance to start the registration of a new agent, retrieve a bearer token that provides admin access to the available functions in the web console. The web console contains multiple possibilities to execute arbitrary commands on both the agents (e.g., via PreCommands for a backup) and also the appliance (e.g., via a Validation job on the agent of the appliance). These options can easily be set with the provided bearer token, which leads to a complete compromise of all agents and the appliance itself.

This Metasploit module exploits a missing authentication vulnerability affecting FortiManager and FortiManager Cloud devices to achieve unauthenticated RCE with root privileges. The vulnerable FortiManager versions are 7.6.0, 7.4.0 through 7.4.4, 7.2.0 through 7.2.7, 7.0.0 through 7.0.12, 6.4.0 through 6.4.14, and 6.2.0 through 6.2.12. The vulnerable FortiManager Cloud versions are 7.4.1 through 7.4.4, 7.2.1 through 7.2.7, 7.0.1 through 7.0.12, and 6.4 (all versions).

On Asterisk, prior to versions 18.24.2, 20.9.2, and 21.4.2 and certified-asterisk versions 18.9-cert11 and 20.7-cert2, an AMI user with write=originate may change all configuration files in the /etc/asterisk/ directory. Writing a new extension can be created which performs a system command to achieve RCE as the asterisk service user (typically asterisk). Default parking lot in FreePBX is called "Default lot" on the website interface, however its actually parkedcalls. Tested against Asterisk 19.8.0 and 18.16.0 on Freepbx SNG7-PBX16-64bit-2302-1.
