F5 Big-ip Application Acceleration Manager 12.1.1

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM, and WebSafe 11.5.1 HF6 through 11.5.4 HF4, 11.6.0 through 11.6.1 HF1, and 12.0.0 through 12.1.2 on VIPRION platforms only, the script which synchronizes SafeNet External Network HSM configuration elements between blades in a clustered deployment will log the HSM partition password in cleartext to the "/var/log/ltm" log file.

Platform dependent weakness. This issue only impacts iSeries platforms. On these platforms, in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator) versions 14.0.0-14.1.0.1, 13.0.0-13.1.1.3, and 12.1.1 HF2-12.1.4, the secureKeyCapable attribute was not set which causes secure vault to not use the F5 hardware support to store the unit key. Instead the unit key is stored in plaintext on disk as would be the case for Z100 systems. Additionally this causes the unit key to be stored in UCS files taken on these platforms.

In some circumstances, an F5 BIG-IP version 12.0.0 to 12.1.2 and 13.0.0 Azure cloud instance may contain a default administrative password which could be used to remotely log into the BIG-IP system. The impacted administrative account is the Azure instance administrative user that was created at deployment. The root and admin accounts are not vulnerable. An attacker may be able to remotely access the BIG-IP host via SSH.

In F5 BIG-IP 12.0.0 through 12.1.2, an authenticated attacker may be able to cause an escalation of privileges through a crafted iControl REST connection.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and Websafe software version 12.0.0 to 12.1.1, 11.6.0 to 11.6.1, 11.5.0 - 11.5.4, virtual servers with a configuration using the HTTP Explicit Proxy functionality and/or SOCKS profile are vulnerable to an unauthenticated, remote attack that allows modification of BIG-IP system configuration, extraction of sensitive system files, and/or possible remote command execution on the BIG-IP system.

An undisclosed traffic pattern received by a BIG-IP Virtual Server with TCP Fast Open enabled may cause the Traffic Management Microkernel (TMM) to restart, resulting in a Denial-of-Service (DoS).

A BIG-IP virtual server configured with a Client SSL profile that has the non-default Session Tickets option enabled may leak up to 31 bytes of uninitialized memory. A remote attacker may exploit this vulnerability to obtain Secure Sockets Layer (SSL) session IDs from other sessions. It is possible that other data from uninitialized memory may be returned as well.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and Websafe software version 13.0.0, 12.0.0 to 12.1.2 and 11.5.1 to 11.6.1, under limited circumstances connections handled by a Virtual Server with an associated SOCKS profile may not be properly cleaned up, potentially leading to resource starvation. Connections may be left in the connection table which then can only be removed by restarting TMM. Over time this may lead to the BIG-IP being unable to process further connections.

The Traffic Management Microkernel (TMM) in F5 BIG-IP before 11.5.4 HF3, 11.6.x before 11.6.1 HF2 and 12.x before 12.1.2 does not properly handle minimum path MTU options for IPv6, which allows remote attackers to cause a denial-of-service (DoS) through unspecified vectors.

On the BIG-IP 2000s, 2200s, 4000s, 4200v, i5600, i5800, i7600, i7800, i10600,i10800, and VIPRION 4450 blades, running version 11.5.0, 11.5.1, 11.5.2, 11.5.3, 11.5.4, 11.6.0, 11.6.1, 12.0.0, 12.1.0, 12.1.1 or 12.1.2 of BIG-IP LTM, AAM, AFM, Analytics, ASM, DNS, GTM or PEM, an undisclosed sequence of packets sent to Virtual Servers with client or server SSL profiles may cause disruption of data plane services.

In F5 BIG-IP 12.1.0 through 12.1.2, specific websocket traffic patterns may cause a disruption of service for virtual servers configured to use the websocket profile.

On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, a flaw in the way reply ICMP packets are limited in the Traffic Management Microkernel (TMM) allows an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

iControl REST in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Link Controller, PEM, and WebSafe 12.0.0 through 12.1.2 and 13.0.0 includes a service to convert authorization BIGIPAuthCookie cookies to X-F5-Auth-Token tokens. This service does not properly re-validate cookies when making that conversion, allowing once-valid but now expired cookies to be converted to valid tokens.

In F5 BIG-IP 12.1.0 through 12.1.2, permissions enforced by iControl can lag behind the actual permissions assigned to a user if the role_map is not reloaded between the time the permissions are changed and the time of the user's next request. This is a race condition that occurs rarely in normal usage; the typical period in which this is possible is limited to at most a few seconds after the permission change.

On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, when an Internet Content Adaptation Protocol (ICAP) profile is configured on a virtual server, undisclosed traffic can cause an increase in Traffic Management Microkernel (TMM) memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

In F5 BIG-IP 11.2.1, 11.4.0 through 11.6.1, and 12.0.0 through 12.1.2, an unauthenticated user with access to the control plane may be able to delete arbitrary files through an undisclosed mechanism.

On F5 BIG-IP 15.1.x versions prior to 15.1.0.2, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, when a DNS listener is configured on a virtual server with DNS queueing (default), undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

In F5 BIG-IP AAM and PEM software version 12.0.0 to 12.1.1, 11.6.0 to 11.6.1, 11.4.1 to 11.5.4, a remote attacker may create maliciously crafted HTTP request to cause Traffic Management Microkernel (TMM) to restart and temporarily fail to process traffic. This issue is exposed on virtual servers using a Policy Enforcement profile or a Web Acceleration profile. Systems that do not have BIG-IP AAM module provisioned are not vulnerable. The Traffic Management Microkernel (TMM) may restart and temporarily fail to process traffic. Systems that do not have BIG-IP AAM or PEM module provisioned are not vulnerable.

Under certain conditions for BIG-IP systems using a virtual server with an associated FastL4 profile and TCP analytics profile, a specific sequence of packets may cause the Traffic Management Microkernel (TMM) to restart.

Virtual servers in F5 BIG-IP systems 11.6.1 before 11.6.1 HF1 and 12.1.x before 12.1.2, when configured to parse RADIUS messages via an iRule, allow remote attackers to cause a denial of service (Traffic Management Microkernel restart) via crafted network traffic.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, 11.2.1, in some cases TMM may crash when processing TCP traffic. This vulnerability affects TMM via a virtual server configured with TCP profile. Traffic processing is disrupted while Traffic Management Microkernel (TMM) restarts. If the affected BIG-IP system is configured to be part of a device group, it will trigger a failover to the peer device.

In F5 BIG-IP LTM, AAM, AFM, APM, ASM, Link Controller, PEM, PSM software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, when a virtual server uses the standard configuration of HTTP/2 or SPDY profile with Client SSL profile, and the client initiates a number of concurrent streams beyond the advertised limit can cause a disruption of service. Remote client initiating stream beyond the advertised limit can cause a disruption of service. The Traffic Management Microkernel (TMM) data plane is exposed to this issue; the control plane is not exposed.

F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1 are vulnerable to a denial of service attack when the MPTCP option is enabled on a virtual server. Data plane is vulnerable when using the MPTCP option of a TCP profile. There is no control plane exposure. An attacker may be able to disrupt services by causing TMM to restart hence temporarily failing to process traffic.

In F5 BIG-IP systems 12.1.0 - 12.1.2, malicious requests made to virtual servers with an HTTP profile can cause the TMM to restart. The issue is exposed with BIG-IP APM profiles, regardless of settings. The issue is also exposed with the non-default "Normalize URI" configuration options used in iRules and/or BIG-IP LTM policies. An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, and WebSafe 11.6.1 HF1, 12.0.0 HF3, 12.0.0 HF4, and 12.1.0 through 12.1.2, undisclosed traffic patterns received while software SYN cookie protection is engaged may cause a disruption of service to the Traffic Management Microkernel (TMM) on specific platforms and configurations.

In F5 BIG-IP LTM, AAM, AFM, APM, ASM, Link Controller, PEM, and WebSafe 12.1.0 through 12.1.2, certain values in a TLS abbreviated handshake when using a client SSL profile with the Session Ticket option enabled may cause disruption of service to the Traffic Management Microkernel (TMM). The Session Ticket option is disabled by default.

In some cases the MCPD binary cache in F5 BIG-IP devices may allow a user with Advanced Shell access, or privileges to generate a qkview, to temporarily obtain normally unrecoverable information.

A stored cross-site scripting (XSS) vulnerability in the Configuration utility device name change page in BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, WOM and WebSafe version 12.0.0 - 12.1.2, 11.4.0 - 11.6.1, and 11.2.1 allows an authenticated user to inject arbitrary web script or HTML. Exploitation requires Resource Administrator or Administrator privileges, and it could cause the Configuration utility client to become unstable.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, WebAccelerator software version 12.0.0 - 12.1.2, 11.6.0 - 11.6.1, 11.4.0 - 11.5.4, 11.2.1, when ConfigSync is configured, attackers on adjacent networks may be able to bypass the TLS protections usually used to encrypted and authenticate connections to mcpd. This vulnerability may allow remote attackers to cause a denial-of-service (DoS) attack via resource exhaustion.
