F5 BIG-IP vulnerabilities

In F5 BIG-IP versions 11.2.1, 11.4.0 through 11.6.1, and 12.0.0 through 12.1.2, an unauthenticated user with access to the control plane may be able to delete arbitrary files through an undisclosed mechanism.

In F5 BIG-IP versions 12.1.0 through 12.1.2, a race condition can occur that may delay the enforcement of permissions by iControl. If the role_map is not reloaded after permissions are changed, a user may gain access to resources they should not have access to.

In F5 BIG-IP versions 12.1.0 through 12.1.2, specific websocket traffic patterns may cause a disruption of service for virtual servers configured to use the websocket profile.

In F5 BIG-IP versions 12.0.0 through 12.1.2, an authenticated attacker may gain elevated privileges through a crafted iControl REST connection.

The Traffic Management Microkernel (TMM) in F5 BIG-IP before 11.5.4 HF3, 11.6.x before 11.6.1 HF2 and 12.x before 12.1.2 does not properly handle minimum path MTU options for IPv6, allowing remote attackers to cause a denial-of-service (DoS) through unspecified vectors.

F5 BIG-IP versions before 12.0.0 HF3 allow remote authenticated users to modify the account configuration of users with the Resource Administration role, potentially gaining privileges via a crafted external Extended Application Verification (EAV) monitor script.

Virtual servers in F5 BIG-IP 11.5.4, when SSL profiles are enabled, allow remote attackers to cause a denial of service through resource consumption and Traffic Management Microkernel restart via an SSL alert during the handshake.

The bigconf.conf file in F5 BIG/ip version 2.1.2 and earlier allows remote attackers to read arbitrary files by specifying the target file in the 'file' parameter.

A vulnerability in SSL profiles on a virtual server can cause it to stop processing new client connections due to undisclosed traffic. The issue affects software versions that have not reached End of Technical Support.

Incorrect permission assignment vulnerabilities exist in iControl REST and TMOS shell (tmsh) undisclosed command, allowing an authenticated attacker to view sensitive information.

A vulnerability in BIG-IP allows termination of the TMM process via undisclosed traffic when a SIP profile is configured on a virtual server. The issue affects F5 Networks software.

A vulnerability in iControl REST and TMOS Shell (tmsh) allows an authenticated attacker with at least the Manager role to create configuration objects that enable arbitrary command execution.

When a BIG-IP is configured with DNS caching (such as a DNS profile with caching enabled, SSL Orchestrator, Advanced WAF DoS protection), undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
