Under certain conditions, a data leak may occur in the Traffic Management Microkernels (TMMs) of BIG-IP tenants running on VELOS and rSeries platforms. This leak occurs randomly and cannot be deliberately triggered. If it occurs, it may leak up to 64 bytes of non-contiguous randomized bytes. Under rare conditions, this may lead to a TMM restart, affecting availability.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

BIG-IP Next Central Manager (CM) may allow an unauthenticated, remote attacker to obtain the BIG-IP Next LTM/WAF instance credentials.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. Show less

A stored 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.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. Show less

When an SSL profile with alert timeout is configured with a non-default value on a virtual server, undisclosed traffic along with conditions beyond the attacker's control can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

An origin validation vulnerability exists in BIG-IP APM browser network access VPN client for Windows, macOS and Linux which may allow an attacker to bypass F5 endpoint inspection. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

Exposure of Sensitive Information vulnerability exists in the GSLB container, which may allow an authenticated attacker with local access to view sensitive information.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. Show less

A DOM-based 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.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

When BIG-IP AFM is licensed and provisioned, undisclosed DNS traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.Show less

When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed requests can cause NGINX worker processes to terminate. Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental. For more information, refer to Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html . Note: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module, undisclosed requests can cause NGINX worker processes to terminate. Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental. For more information, refer to Support for QUIC and HTTP/3 https://nginx.org/en/docs/quic.html .

When LDAP remote authentication is configured on F5OS, a remote user without an assigned role will be incorrectly authorized.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.Show less

When a virtual server is enabled with VLAN group and SNAT listener is configured, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

When a BIG-IP PEM classification profile is configured on a UDP virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. This issue affects classification engines using signatures released between 09-08-2022 and 02-16-2023. See the table in the F5 Security Advisory for a complete list of affected classification signature files.  NOTE: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

When SSL Client Certificate LDAP or Certificate Revocation List Distribution Point (CRLDP) authentication profile is configured on a virtual server, undisclosed requests can cause an increase in CPU resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

When running in Appliance mode, an authenticated attacker assigned the Administrator role may be able to bypass Appliance mode restrictions utilizing iAppsLX templates on a BIG-IP system.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluatedShow less

Undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. For the Application Visibility and Reporting module, this may occur when the HTTP Analytics profile with URLs enabled under Collected Entities is configured on a virtual server and the DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled. For BIG-IP Advanced WAF and ASM, this may occur when either a DoS or Bot Defense profile is configured on a virtual server and the DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled. Note: The DB variables avr.IncludeServerInURI and avr.CollectOnlyHostnameFromURI are not enabled by default. For more information about the HTTP Analytics profile and the Collect URLs setting, refer to K30875743: Create a new Analytics profile and attach it to your virtual servers https://my.f5.com/manage/s/article/K30875743 .
