K25434422:NGINX Controller vulnerability CVE-2020-5899
Security Advisory
Original Publication Date: 11 Jun, 2020
Security Advisory Description
Recovery code required to change a user's password is transmitted and stored in
the database in plain text, which allows an attacker who can intercept the
database connection or have read access to the database, to request a password
reset using the email address of another registered user then retrieve the
recovery code. (CVE-2020-5899)
Impact
With the extracted recovery code, the attacker can change the password of the
victim user. If the victim user is an admin user, the attacker can gain full
control of the NGINX Controller system.
Security Advisory Status
F5 Product Development has assigned IND-11092 (NGINX Controller) to this
vulnerability.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases, point releases, or
hotfixes that address the vulnerability, refer to the following table. For more
information about security advisory versioning, refer to K51812227:

^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.
Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.
Mitigation
To mitigate this vulnerability, you can enable SSL connections to the database,
or connect to the database by way of a secure, private network. Use a database
instance dedicated to the controller, preventing any other users from accessing
the database.

Original Publication Date: 11 Jun, 2020
Security Advisory Description
Insufficient cross-site request forgery (CSRF) protections for the NGINX
Controller user interface. (CVE-2020-5900)
Impact
An attacker can exploit this vulnerability by enticing a victim user to follow
