F5 Big-ip Access Policy Manager

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.

In versions bundled with BIG-IP APM 12.1.0-12.1.5 and 11.6.1-11.6.5.2, Edge Client for Linux exposes full session ID in the local log files.

On BIG-IP versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, BIG-IQ versions 7.0.0, 6.0.0-6.1.0, and 5.0.0-5.4.0, iWorkflow version 2.3.0, and Enterprise Manager version 3.1.1, authenticated users granted TMOS Shell (tmsh) privileges are able access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to access objects on the file system which would not normally be allowed.

The BIG-IP APM Edge Client for macOS bundled with BIG-IP APM 15.0.0-15.0.1, 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.1.0-13.1.1.5, 12.1.0-12.1.5, and 11.5.1-11.6.5 may allow unprivileged users to access files owned by root.

In versions 7.1.5-7.1.9, BIG-IP Edge Client Windows Stonewall driver does not sanitize the pointer received from the userland. A local user on the Windows client system can send crafted DeviceIoControl requests to \\.\urvpndrv device causing the Windows kernel to crash.

On F5 BIG-IP APM 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, as well as F5 BIG-IP APM Clients 7.x versions prior to 7.2.1.5, BIG-IP Edge Client may log sensitive APM session-related information when VPN is launched on a Windows system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

BIGIP and BIG-IQ TACACS+ audit log Vulnerability

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.

On versions 15.1.0-15.1.0.1, 15.0.0-15.0.1.2, and 14.1.0-14.1.2.3, in BIG-IP APM portal access, a specially crafted HTTP request can lead to reflected XSS after the BIG-IP APM system rewrites the HTTP response from the untrusted backend server and sends it to the client.

On BIG-IP APM 14.0.0 to 14.0.0.4, 13.0.0 to 13.1.1.3 and 12.1.0 to 12.1.3.7, a reflected cross-site scripting (XSS) vulnerability exists in the resource information page for authenticated users when a full webtop is configured on the BIG-IP APM system.

In versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, and 14.1.0-14.1.2.3, a stored cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Traffic Management User Interface (TMUI), also known as the BIG-IP Configuration utility.

In BIG-IP APM portal access on versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, when backend servers serve HTTP pages with special JavaScript code, this can lead to internal portal access name conflict.

In BIG-IP versions 15.0.0-15.1.0.4, 14.1.0-14.1.2.6, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1 and BIG-IQ versions 5.4.0-7.0.0, Self-IP port-lockdown bypass via IPv6 link-local addresses.

On F5 BIG-IP 13.0.0-13.1.0.5 or 12.0.0-12.1.3.3, malicious root users with access to a VCMP guest can cause a disruption of service on adjacent VCMP guests running on the same host. Exploiting this vulnerability causes the vCMPd process on the adjacent VCMP guest to restart and produce a core file. This issue is only exploitable on a VCMP guest which is operating in "host-only" or "bridged" mode. VCMP guests which are "isolated" are not impacted by this issue and do not provide mechanism to exploit the vulnerability. Guests which are deployed in "Appliance Mode" may be impacted however the exploit is not possible from an Appliance Mode guest. To exploit this vulnerability root access on a guest system deployed as "host-only" or "bridged" mode is required.

Under certain conditions, TMM may restart and produce a core file while processing APM data on BIG-IP 13.0.1 or 13.1.0.4-13.1.0.7.

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.

In BIG-IP APM versions 12.1.0-12.1.5.1 and 11.6.1-11.6.5.2, RADIUS authentication leaks memory when the username for authentication is not set.
