In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, WebAccelerator and WebSafe software version 13.0.0, 12.0.0 - 12.1.2, 11.6.0 - 11.6.1 and 11.5.0 - 11.5.4, in some circumstances, Traffic Management Microkernel (TMM) does not properly handle certain malformed TLS1.2 records, which allows remote attackers to cause a denial-of-service (DoS) or possible remote command execution on the BIG-IP system.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and WebSafe software version 13.0.0, 12.1.0 - 12.1.2 and 11.5.1 - 11.6.1, an undisclosed sequence of packets, sourced from an adjacent network may cause TMM to crash.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and Websafe software version 13.0.0, 12.0.0 to 12.1.2, 11.6.0 to 11.6.1 and 11.5.0 - 11.5.4, an undisclosed sequence of packets sent to BIG-IP High Availability state mirror listeners (primary and/or secondary IP) may cause TMM to restart.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and Websafe software version 12.0.0 to 12.1.1, 11.6.0 to 11.6.1, 11.5.0 - 11.5.4, virtual servers with a configuration using the HTTP Explicit Proxy functionality and/or SOCKS profile are vulnerable to an unauthenticated, remote attack that allows modification of BIG-IP system configuration, extraction of sensitive system files, and/or possible remote command execution on the BIG-IP system.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM, and WebSafe 11.5.1 HF6 through 11.5.4 HF4, 11.6.0 through 11.6.1 HF1, and 12.0.0 through 12.1.2 on VIPRION platforms only, the script which synchronizes SafeNet External Network HSM configuration elements between blades in a clustered deployment will log the HSM partition password in cleartext to the "/var/log/ltm" log file.

A stored cross-site scripting (XSS) vulnerability in the Configuration utility device name change page in BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, WOM and WebSafe version 12.0.0 - 12.1.2, 11.4.0 - 11.6.1, and 11.2.1 allows an authenticated user to inject arbitrary web script or HTML. Exploitation requires Resource Administrator or Administrator privileges, and it could cause the Configuration utility client to become unstable.

In F5 BIG-IP 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 LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, and WebSafe 11.6.1 HF1, 12.0.0 HF3, 12.0.0 HF4, and 12.1.0 through 12.1.2, undisclosed traffic patterns received while software SYN cookie protection is engaged may cause a disruption of service to the Traffic Management Microkernel (TMM) on specific platforms and configurations.

An attacker may be able to cause a denial-of-service (DoS) attack against the sshd component in F5 BIG-IP, Enterprise Manager, BIG-IQ, and iWorkflow.

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, which allows remote attackers to cause a denial-of-service (DoS) through unspecified vectors.

In some cases the MCPD binary cache in F5 BIG-IP devices may allow a user with Advanced Shell access, or privileges to generate a qkview, to temporarily obtain normally unrecoverable information.

F5 BIG-IP 12.0.0 and 11.5.0 - 11.6.1 REST requests which timeout during user account authentication may log sensitive attributes such as passwords in plaintext to /var/log/restjavad.0.log. It may allow local users to obtain sensitive information by reading these files.

Virtual servers in F5 BIG-IP systems 11.5.0, 11.5.1 before HF11, 11.5.2, 11.5.3, 11.5.4 before HF2, 11.6.0 before HF8, 11.6.1 before HF1, 12.0.0 before HF4, and 12.1.0 before HF2, when configured with the HTTP Explicit Proxy functionality or SOCKS profile, allow remote attackers to modify the system configuration, read system files, and possibly execute arbitrary code via unspecified vectors.
