  - GONICUS GOsa version before commit 56070d6289d47ba3f5918885954dcceb75606001 contains a Cross Site
    Scripting (XSS) vulnerability in change password form (html/password.php, #308) that can result in
    injection of arbitrary web script or HTML. This attack appear to be exploitable via the victim must open a
    specially crafted web page. This vulnerability appears to have been fixed in after commit
    56070d6289d47ba3f5918885954dcceb75606001. (CVE-2018-1000528)

  - Incorrect Access Control in the LDAP class of GONICUS GOsa through 2019-04-11 allows an attacker to log
    into any account with a username containing the case-insensitive substring success when an arbitrary
    password is provided. (CVE-2019-11187)

  - The GOsa_Filter_Settings cookie in GONICUS GOsa 2.7.5.2 is vulnerable to PHP objection injection, which
    allows a remote authenticated attacker to perform file deletions (in the context of the user account that
    runs the web server) via a crafted cookie value, because unserialize is used to restore filter settings
    from a cookie. (CVE-2019-14466)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
