Title
GYM One admin user list is vulnerable to stored cross-site scripting
Summary
GYM One is open-source gym management software for fitness centers, personal trainers, and sports clubs. Prior to 1.4.1, GYM One's admin/users/index.php renders the stored firstname, lastname, and email profile fields into the administrator user list without HTML output encoding. An attacker who can store values in those fields can cause content to execute in an administrator's browser when the administrator visits /admin/users/. The persistent script can access administrator-session data or perform actions with the administrator's privileges until the stored record is removed. This issue is fixed in version 1.4.1.
Severity
8.7 (High)

Title
GYM One: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in admin/users/index.php
Summary
GYM One is open-source gym management software for fitness centers, personal trainers, and sports clubs. Prior to 1.4.1, GYM One's admin/users/index.php concatenates the search_name and search_email GET parameters into both the user-list query and the COUNT query used for pagination without prepared statements. An authenticated administrator can inject SQL through either search field to read data from arbitrary tables, including user information and password hashes. Depending on database permissions, the same injection may also permit filesystem writes. This issue is fixed in version 1.4.1.
