Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4609-1 advisory.

 Fabian Henneke discovered that GOsa incorrectly handled client cookies. An authenticated user could exploit this with a crafted cookie to perform 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
