Eclipse Kura versions prior to 5.6.2 trust the client-supplied X-Forwarded-For HTTP header as the authoritative source of the client IP address in audit log entries. The org.eclipse.kura.web2 (Web Console) and org.eclipse.kura.rest.provider (REST API) components use this header as the primary IP source when initializing audit context, and org.eclipse.kura.jetty.customizer unconditionally installs Jetty's ForwardedRequestCustomizer on all HTTP/HTTPS connectors, causing HttpServletRequest.getRemoteAddr() to reflect the attacker-controlled header value. An unauthenticated remote attacker can exploit this vulnerability to bypass IP-based brute-force protections — such as fail2ban — by spoofing the logged IP address to a non-routable value, allowing a brute-force attack to proceed undetected, or to cause a denial of service against a third party by injecting a victim's IP address and triggering a ban on that address.

In Eclipse Kura LogServlet component included in versions 5.0.0 to 5.4.1, a specifically crafted request to the servlet can allow an unauthenticated user to retrieve the device logs. Also, downloaded logs may be used by an attacker to perform privilege escalation by using the session id of an authenticated user reported in logs.

This issue affects org.eclipse.kura:org.eclipse.kura.web2 version range [2.0.600, 2.4.0], which is included in Eclipse Kura version range [5.0.0, 5.4.1]

In Eclipse Kura versions up to 4.0.0, the SkinServlet did not checked the path passed during servlet call, potentially allowing path traversal in get requests for a limited number of file types.

In Eclipse Kura versions up to 4.0.0, Kura exposes the underlying Ui Web server version in its replies. This can be used as a hint by an attacker to specifically craft attacks to the web server run by Kura.

In Eclipse Kura versions up to 4.0.0, the Web UI package and component services, the Artemis simple Mqtt component and the emulator position service (not part of the device distribution) could potentially be target of XXE attack due to an improper factory and parser initialisation.

The network enabled distribution of Kura before 2.1.0 takes control over the device's firewall setup but does not allow IPv6 firewall rules to be configured. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox "exec" command. As the process is running as "root" full control over the device can be acquired. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address.
