When TCP Verified Accept is enabled on a TCP profile that is configured on a Virtual Server, undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
Undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate when a client-side HTTP/2 profile and the HTTP MRF Router option are enabled for a virtual server and an iRule using the HTTPREQUEST event or Local Traffic Policy are associated with the virtual server. TMM can also terminate when a client-side HTTP/2 profile and the HTTP MRF Router option are enabled, regardless of the presence of the iRule.
When a non-admin user has been assigned an administrator role via an iControl REST PUT request and later the user's role is reverted back to a non-admin role via the Configuration utility, tmsh, or iControl REST, the BIG-IP non-admin user can still access the iControl REST admin resource.
An authenticated user's session cookie may remain valid for a limited time after logging out from the BIG-IP Configuration utility on a multi-blade VIPRION platform.
The BIG-IP Edge Client Installer on macOS does not follow best practices for elevating privileges during the installation process.
A directory traversal vulnerability exists in the BIG-IP Configuration Utility that may allow an authenticated attacker to execute commands on the BIG-IP system. For BIG-IP system running in Appliance mode, a successful exploit can allow the attacker to cross a security boundary.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Specific F5 BIG-IP platforms with Cavium Nitrox FIPS HSM cards generate a deterministic password for the Crypto User account. The predictable nature of the password allows an authenticated user with TMSH access to the BIG-IP system, or anyone with physical access to the FIPS HSM, the information required to generate the correct password. On vCMP systems, all Guests share the same deterministic password, allowing those with TMSH access on one Guest to access keys of a different Guest.
The following BIG-IP hardware platforms are affected: 10350v-F, i5820-DF, i7820-DF, i15820-DF, 5250v-F, 7200v-F, 10200v-F, 6900-F, 8900-F, 11000-F, and 11050-F.
The BIG-IP rSeries r5920-DF and r10920-DF are not affected, nor does the issue affect software FIPS implementations or network HSM configurations.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an attacker to run JavaScript in the context of the currently logged-in user.
An authenticated attacker with guest privileges or higher can cause the iControl SOAP process to terminate by sending undisclosed requests.
A reflected cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an attacker to run JavaScript in the context of the currently logged-in user.
When an SSL profile is configured on a Virtual Server, undisclosed traffic can cause an increase in CPU or SSL accelerator resource utilization.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
When a UDP profile with Idle Timeout set to Immediate or the value 0 is configured on a virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.
A directory traversal vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that may allow an authenticated attacker to read files with an .xml extension. Access to restricted information is limited and the attacker does not control what information is obtained.
Multiple reflected cross-site scripting (XSS) vulnerabilities exist in undisclosed pages of the BIG-IP Configuration utility that allow an attacker to run JavaScript in the context of the currently logged-in user.
The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.
An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GETRESTRICT control message, which could let a malicious user obtain sensitive information.
On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, 12.1.0-12.1.4.1, and 11.5.1-11.6.4, when the BIG-IP system is licensed with Appliance mode, user accounts with Administrator and Resource Administrator roles can bypass Appliance mode restrictions.
On BIG-IP 11.5.1-11.6.4, iRules performing HTTP header manipulation may cause an interruption to service when processing traffic handled by a Virtual Server with an associated HTTP profile, in specific circumstances, when the requests do not strictly conform to RFCs.
On BIG-IP 14.1.0-14.1.0.5, undisclosed SSL traffic to a virtual server configured with a Client SSL profile may cause TMM to fail and restart. The Client SSL profile must have session tickets enabled and use DHE cipher suites to be affected. This only impacts the data plane, there is no impact to the control plane.
On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, 12.1.0-12.1.4, and 11.5.1-11.6.4, a reflected 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.
