# X-Backend-Server header exposes server information
|
||
|
|
||
|
## Description
|
||
|
|
||
|
The target website returns the `X-Backend-Server` header which includes potentially internal/hidden IP addresses
|
||
|
or hostnames. By exposing these values, attackers may attempt to circumvent security proxies and access these
|
||
|
hosts directly.
|
||
|
|
||
|
## Remediation
|
||
|
|
||
|
Consult your proxy/load balancer documentation or provider on how to disable revealing the
|
||
|
`X-Backend-Server` header value.
