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.

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 evaluated

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 evaluated

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 evaluated

When HTTP/2 is configured on BIG-IP or BIG-IP Next SPK systems, undisclosed responses can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

When BIG-IP is deployed in high availability (HA) and an iControl REST API token is updated, the change does not sync to the peer device. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

When running in appliance mode, an authenticated remote command injection vulnerability exists in an undisclosed iControl REST endpoint on multi-bladed systems. 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

BIG-IP or BIG-IQ Resource Administrators and Certificate Managers who have access to the secure copy (scp) utility but do not have access to Advanced shell (bash) can execute arbitrary commands with a specially crafted command string. This vulnerability is due to an incomplete fix for CVE-2020-5873. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

An insufficient verification of data vulnerability exists in BIG-IP Edge Client Installer on macOS that may allow an attacker elevation of privileges during the installation process.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Exposure of Sensitive Information vulnerability exist in an undisclosed BIG-IP TMOS shell (tmsh) command which may allow an authenticated attacker with resource administrator role privileges to view sensitive information.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
