Through undisclosed methods, on F5 BIG-IP 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.0-11.6.3.1, or 11.2.1-11.5.6, adjacent network attackers can cause a denial of service for VCMP guest and host systems. Attack must be sourced from adjacent network (layer 2).
A remote attacker may be able to disrupt services on F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.5, 11.6.0-11.6.3.1, or 11.2.1-11.5.6 if the TMM virtual server is configured with a HTML or a Rewrite profile. TMM may restart while processing some specially prepared HTML content from the back end.
On F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.0-11.6.3.1, or 11.2.1-11.5.6 a domain name cached within the DNS Cache of TMM may continue to be resolved by the cache even after the parent server revokes the record, if the DNS Cache is receiving a stream of requests for the cached name.
Under certain conditions on F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.0-11.6.3.1, or 11.5.0-11.5.6, TMM may core while processing SSL forward proxy traffic.
Under certain conditions on F5 BIG-IP 13.1.0-13.1.0.5, 13.0.0, 12.1.0-12.1.3.1, 11.6.0-11.6.3.1, or 11.5.0-11.5.6, TMM may core while processing SSL forward proxy traffic.
On F5 BIG-IP 14.0.0, 13.0.0-13.1.0, 12.1.0-12.1.3, or 11.5.1-11.6.3 specifically crafted HTTP responses, when processed by a Virtual Server with an associated QoE profile that has Video enabled, may cause TMM to incorrectly buffer response data causing the TMM to restart resulting in a Denial of Service.
On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2, or 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, or F5 iWorkflow 2.0.2-2.3.0, authenticated users granted TMOS Shell (tmsh) access can access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed.
On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.3, or 11.2.1-11.6.3.1, administrative users by way of undisclosed methods can exploit the ssldump utility to write to arbitrary file paths. For users who do not have Advanced Shell access (for example, any user when licensed for Appliance Mode), this allows more permissive file access than intended.
On an F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.1, or 11.2.1-11.6.3.1 system configured in Appliance mode, the TMOS Shell (tmsh) may allow an administrative user to use the dig utility to gain unauthorized access to file system resources.
