    file deletions in the context of the user account that runs the web
    server. (CVE-2019-14466)
    It was discovered that GOsa incorrectly handled user access control. A
    remote attacker could use this issue to log into any account with a
    username containing the word "success". (CVE-2019-11187)
    Fabian Henneke discovered that GOsa was vulnerable to cross-site scripting
    attacks via the change password form. A remote attacker could use this
    flaw to run arbitrary web scripts. (CVE-2018-1000528)
