[Google] Admin access to FS KVM Switch

On http://XXX.XXX.XX.XX, there was a login portal over "/login.html" for Google Admins to access FS KVM Switch.

The portal served as single console for multiple network server.
The "/index.html" was not accessible without assigned authenticated cookies.

Due to having default creds, a login was possible as the Admin which redirected to "/index.html", assuming a successful login was made.
The interface showed an iframe within to list devices which was empty.

I stopped my testing at this point because of the latency of the responses was really high, which gave me an indication that further testings with tools might result in server getting throttled.

[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 MoczadÅ‚o 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 ).
