1) Security restrictions bypass
EUVDB-ID: #VU8921
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-6145
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain unauthorized access to the iControl REST API.
The weakness exists in the iControl REST API of multiple F5 BIG-IP systems due to improper validation of cookies when the
iControl REST API converts BIGIPAuthCookie
authorization cookies to X-F5-Auth-Token tokens.A remote attcker can obtain an expired BIG-IP authentication cookie could exploit this
vulnerability to access valid iControl REST tokens, which could be used
to access the iControl REST API on a targeted system.
