Security Advisory Description
Apache modules apache_auth_token_mod and mod_auth_f5_auth_token.cpp allow
possible unauthenticated bruteforce on the em_server_ip authorization parameter
to obtain which SSL client certificates used for mutual authentication between
BIG-IQ or Enterprise Manager (EM) and managed BIG-IP devices. (CVE-2018-5506)
Impact
This vulnerability can disclose the em_server_ip field of valid client
certificates. This does not reveal the certificate needed for authentication.
Security Advisory Status
F5 Product Development has assigned ID 572272 (BIG-IP) and ID 663962
(Enterprise Manager) to this vulnerability.

^1 The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.
^2 The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.
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.
