EPSS estimates a 0.27% chance of exploitation in the next 30 days.

Description

HAXiam is a packaging wrapper for HAXcms which allows anyone to spawn their own microsite management platform. In versions 11.0.4 and below, the application returns a 200 response when requesting the data of a valid user and a 404 response when requesting the data of an invalid user. This can be used to infer the existence of valid user accounts. An authenticated attacker can use automated tooling to brute force potential usernames and use the application's response to identify valid accounts. This can be used in conjunction with other vulnerabilities, such as the lack of authorization checks, to enumerate and deface another user's sites. This is fixed in version 11.0.5.
