On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.3, or 11.2.1-11.6.3.1, administrative users by way of undisclosed methods can exploit the ssldump utility to write to arbitrary file paths. For users who do not have Advanced Shell access (for example, any user when licensed for Appliance Mode), this allows more permissive file access than intended.7.5CVE-2018-5517f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On F5 BIG-IP 13.1.0-13.1.0.5, malformed TCP packets sent to a self IP address or a FastL4 virtual server may cause an interruption of service. The control plane is not exposed to this issue. This issue impacts the data plane virtual servers and self IPs.7.5CVE-2018-5507f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

In F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.1, 11.5.1-11.5.5, or 11.2.1 the Apache modules apache_auth_token_mod and mod_auth_f5_auth_token.cpp allow possible unauthenticated bruteforce on the em_server_ip authorization parameter to obtain which SSL client certificates used for mutual authentication between BIG-IQ or Enterprise Manager (EM) and managed BIG-IP devices.7.8CVE-2018-5527f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On BIG-IP 13.1.0-13.1.0.7, a remote attacker using undisclosed methods against virtual servers configured with a Client SSL or Server SSL profile that has the SSL Forward Proxy feature enabled can force the Traffic Management Microkernel (tmm) to leak memory. As a result, system memory usage increases over time, which may eventually cause a decrease in performance or a system reboot due to memory exhaustion.7.8CVE-2018-5509f5 networks, inc.big-ip (ltm, aam, afm, apm, asm, link controller, pem, websafe)+8

On F5 BIG-IP versions 13.0.0 or 12.1.0 - 12.1.3.1, when a specifically configured virtual server receives traffic of an undisclosed nature, TMM will crash and take the configured failover action, potentially causing a denial of service. The configuration which exposes this issue is not common and in general does not work when enabled in previous versions of BIG-IP. Starting in 12.1.0, BIG-IP will crash if the configuration which exposes this issue is enabled and the virtual server receives non TCP traffic. With the fix of this issue, additional configuration validation logic has been added to prevent this configuration from being applied to a virtual server. There is only data plane exposure to this issue with a non-standard configuration. There is no control plane exposure.7.5CVE-2018-5514f5 networks, inc.big-ip (ltm, aam, afm, apm, asm, link controller, pem, webaccelerator, websafe)+13

On F5 BIG-IP 13.1.0-13.1.0.5, maliciously crafted HTTP/2 request frames can lead to denial of service. There is data plane exposure for virtual servers when the HTTP2 profile is enabled. There is no control plane exposure to this issue.7.5CVE-2018-5502f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On F5 BIG-IP versions 13.0.0 - 13.1.0.3, attackers may be able to disrupt services on the BIG-IP system with maliciously crafted client certificate. This vulnerability affects virtual servers associated with Client SSL profile which enables the use of client certificate authentication. Client certificate authentication is not enabled by default in Client SSL profile. There is no control plane exposure.5.9CVE-2018-5500f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On F5 BIG-IP systems running 13.0.0, 12.1.0 - 12.1.3.1, or 11.6.1 - 11.6.2, every Multipath TCP (MCTCP) connection established leaks a small amount of memory. Virtual server using TCP profile with Multipath TCP (MCTCP) feature enabled will be affected by this issue.5.9CVE-2018-5522f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

In some circumstances, on F5 BIG-IP systems running 13.0.0, 12.1.0 - 12.1.3.1, any 11.6.x or 11.5.x release, or 11.2.1, TCP DNS profile allows excessive buffering due to lack of flow control.7.5CVE-2018-5513f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On F5 BIG-IP 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, a malformed TLS handshake causes TMM to crash leading to a disruption of service. This issue is only exposed on the data plane when Proxy SSL configuration is enabled. The control plane is not impacted by this issue.5.4CVE-2018-5518f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

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.7.8CVE-2018-5512f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

On an F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.1, or 11.2.1-11.6.3.1 system configured in Appliance mode, the TMOS Shell (tmsh) may allow an administrative user to use the dig utility to gain unauthorized access to file system resources.5.3CVE-2018-5537f5 networks, inc.big-ip (ltm, aam, afm, apm, asm, edge gateway, gtm, pem, webaccelerator, websafe)+10

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.4.7CVE-2018-5516f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+21

On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2, or 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, or F5 iWorkflow 2.0.2-2.3.0, authenticated users granted TMOS Shell (tmsh) access can access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed.6.3CVE-2018-5515f5 networks, inc.big-ip (ltm, aam, afm, analytics, apm, asm, dns, edge gateway, gtm, link controller, pem, webaccelerator, websafe)+13

In some circumstances, the Traffic Management Microkernel (TMM) does not properly handle certain malformed Websockets requests/responses, which allows remote attackers to cause a denial-of-service (DoS) or possible remote code execution on the F5 BIG-IP system running versions 13.0.0 - 13.1.0.3 or 12.1.0 - 12.1.3.1.
