On versions 15.1.0-15.1.0.5, 14.1.0-14.1.3, 13.1.0-13.1.3.5, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, when a BIG-IP APM virtual server processes traffic of an undisclosed nature, the Traffic Management Microkernel (TMM) stops responding and restarts.Show less

On the BIG-IP AFM version 15.1.0-15.1.0.5, 14.1.0-14.1.3, and 13.1.0-13.1.3.5, when a Protocol Inspection Profile is attached to a FastL4 virtual server with the protocol field configured to either Other or All Protocols, the TMM may experience a restart if the profile processes non-TCP traffic.Show less

In version 15.1.0-15.1.0.5, 14.1.0-14.1.3, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2 of BIG-IP DNS, GTM, and Link Controller, zxfrd leaks memory when listing DNS zones. Zones can be listed via TMSH, iControl or SNMP; only users with access to those services can trigger this vulnerability.Show less

In BIG-IP APM versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.4, 15.0.0-15.0.1.3, 14.1.0-14.1.3, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, on systems running more than one TMM instance, authenticated VPN users may consume excessive resources by sending specially-crafted malicious traffic over the tunnel.Show less

In versions 16.0.0-16.0.0.1, 15.1.0-15.1.1, 14.1.0-14.1.3, 13.1.0-13.1.3.5, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, in a BIG-IP DNS / BIG-IP LTM GSLB deployment, under certain circumstances, the BIG-IP DNS system may stop using a BIG-IP LTM virtual server for DNS response.Show less

When a BIG-IP ASM or Advanced WAF system running version 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.3, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, or 11.6.1-11.6.5.2 processes requests with JSON payload, an unusually large number of parameters can cause excessive CPU usage in the BIG-IP ASM bd process.Show less

On BIG-IP versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.2.7, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, undisclosed endpoints in iControl REST allow for a reflected XSS attack, which could lead to a complete compromise of the BIG-IP system if the victim user is granted the admin role.Show less

In certain configurations on version 13.1.3.4, when a BIG-IP AFM HTTP security profile is applied to a virtual server and the BIG-IP system receives a request with specific characteristics, the connection is reset and the Traffic Management Microkernel (TMM) leaks memory.Show less

In versions 16.0.0-16.0.0.1 and 15.1.0-15.1.1, on specific BIG-IP platforms, attackers may be able to obtain TCP sequence numbers from the BIG-IP system that can be reused in future connections with the same source and destination port and IP numbers. Only these platforms are affected: BIG-IP 2000 series (C112), BIG-IP 4000 series (C113), BIG-IP i2000 series (C117), BIG-IP i4000 series (C115), BIG-IP Virtual Edition (VE).Show less

In BIG-IP Advanced WAF and FPS versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, and 14.1.0-14.1.2.7, under some circumstances, certain format client-side alerts sent to the BIG-IP virtual server configured with DataSafe may cause the Traffic Management Microkernel (TMM) to restart, resulting in a Denial-of-Service (DoS).Show less

In BIG-IP versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, and 14.1.0-14.1.2.7, undisclosed TMUI page contains a stored cross site scripting vulnerability (XSS). The issue allows a minor privilege escalation for resource admin to escalate to full admin.Show less

In BIG-IQ 7.1.0, accessing the DoS Summary events and DNS Overview pages in the BIG-IQ system interface returns an error message due to disabled Grafana reverse proxy in web service configuration. F5 has done further review of this vulnerability and has re-classified it as a defect. CVE-2020-5944 will continue to be referenced in F5 Security Advisory K57274211 and will not be assigned to other F5 vulnerabilities.Show less

In versions 14.1.0-14.1.0.1 and 14.1.2.5-14.1.2.7, when a BIG-IP object is created or listed through the REST interface, the protected fields are obfuscated in the REST response, not protected via a SecureVault cryptogram as TMSH does. One example of protected fields is the GTM monitor password.Show less

In BIG-IP PEM versions 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.2.7, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, when processing Capabilities-Exchange-Answer (CEA) packets with certain attributes from the Policy and Charging Rules Function (PCRF) server, the Traffic Management Microkernel (TMM) may generate a core file and restart.Show less

On BIG-IP versions 16.0.0-16.0.0.1 and 15.1.0-15.1.0.5, using the RESOLV::lookup command within an iRule may cause the Traffic Management Microkernel (TMM) to generate a core file and restart. This issue occurs when data exceeding the maximum limit of a hostname passes to the RESOLV::lookup command.Show less

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.Show less
