HCL Nomad server on Domino is affected by an open proxy vulnerability in which an unauthenticated attacker can mask their original source IP address. This may enable an attacker to trick the user into exposing sensitive information.

HCL Nomad is susceptible to an insufficient session expiration vulnerability.   Under certain circumstances, an unauthenticated attacker could obtain old session information.

The HTTP host header can be manipulated and cause the application to behave in unexpected ways. Any changes made to the header would cause the request to be sent to a completely different domain/IP address.

"If port encryption is not enabled on the Domino Server, HCL Nomad on Android and iOS Platforms will communicate in clear text and does not currently have a user interface option to change the setting to request an encrypted communication channel with the Domino server. This can potentially expose sensitive information including but not limited to server names, user IDs and document content."

HCL Nomad server on Domino did not configure the frame-ancestors directive in the Content-Security-Policy header by default which could allow an attacker to obtain sensitive information via unspecified vectors.
