The Eurolab ELTS100_UBX device (firmware version ELTS100v1.UBX) is vulnerable to Broken Access Control due to missing authentication on critical administrative endpoints. Attackers can directly access and modify sensitive system and network configurations, upload firmware, and execute unauthorized actions without any form of authentication. This vulnerability allows remote attackers to fully compromise the device, control its functionality, and disrupt its operation.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
Access control involves the use of several protection mechanisms such as:
When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:
