F5 Big-ip Protocol Security Module

The HTTPS protocol, as used in unspecified web applications, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which makes it easier for man-in-the-middle attackers to obtain plaintext secret values by observing length differences during a series of guesses in which a string in an HTTP request URL potentially matches an unknown string in an HTTP response body, aka a "BREACH" attack, a different issue than CVE-2012-4929.

F5 BIG-IP LTM, AFM, Analytics, APM, ASM, Link Controller, and PEM 11.3.x, 11.4.x before 11.4.1 HF10, 11.5.x before 11.5.4, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF1; BIG-IP AAM 11.4.x before 11.4.1 HF10, 11.5.x before 11.5.4, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF1; BIG-IP DNS 12.x before 12.0.0 HF1; BIG-IP Edge Gateway, WebAccelerator, and WOM 11.3.0; BIG-IP GTM 11.3.x, 11.4.x before 11.4.1 HF10, 11.5.x before 11.5.4, and 11.6.x before 11.6.1; BIG-IP PSM 11.3.x and 11.4.x before 11.4.1 HF10; Enterprise Manager 3.0.0 through 3.1.1; BIG-IQ Cloud and BIG-IQ Security 4.0.0 through 4.5.0; BIG-IQ Device 4.2.0 through 4.5.0; BIG-IQ ADC 4.5.0; BIG-IQ Centralized Management 4.6.0; and BIG-IQ Cloud and Orchestration 1.0.0 on the 3900, 6900, 8900, 8950, 11000, 11050, PB100 and PB200 platforms, when software SYN cookies are configured on virtual servers, allow remote attackers to cause a denial of service (High-Speed Bridge hang) via an invalid TCP segment.

An unauthenticated remote attacker may be able to disrupt services on F5 BIG-IP 11.4.1 - 11.5.4 devices with maliciously crafted network traffic. This vulnerability affects virtual servers associated with TCP profiles when the BIG-IP system's tm.tcpprogressive db variable value is set to non-default setting "enabled". The default value for the tm.tcpprogressive db variable is "negotiate". 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, 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.

SSL virtual servers in F5 BIG-IP systems 10.x before 10.2.4 HF9, 11.x before 11.2.1 HF12, 11.3.0 before HF10, 11.4.0 before HF8, 11.4.1 before HF5, 11.5.0 before HF5, and 11.5.1 before HF5, when used with third-party Secure Sockets Layer (SSL) accelerator cards, might allow remote attackers to have unspecified impact via a timing side-channel attack.

On BIG-IP 14.0.0-14.0.0.2 or 13.0.0-13.1.1.1, in certain circumstances, when processing traffic through a Virtual Server with an associated MQTT profile, the TMM process may produce a core file and take the configured HA action.

Multiple XML External Entity (XXE) vulnerabilities in the Configuration utility in F5 BIG-IP LTM, ASM, GTM, and Link Controller 11.0 through 11.6.0 and 10.0.0 through 10.2.4, AAM 11.4.0 through 11.6.0, ARM 11.3.0 through 11.6.0, Analytics 11.0.0 through 11.6.0, APM and Edge Gateway 11.0.0 through 11.6.0 and 10.1.0 through 10.2.4, PEM 11.3.0 through 11.6.0, PSM 11.0.0 through 11.4.1 and 10.0.0 through 10.2.4, and WOM 11.0.0 through 11.3.0 and 10.0.0 through 10.2.4 and Enterprise Manager 3.0.0 through 3.1.1 and 2.1.0 through 2.3.0 allow remote authenticated users to read arbitrary files and cause a denial of service via a crafted request, as demonstrated using (1) viewList or (2) deal elements.

When BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.0.5, 12.1.0-12.1.3.5, 11.6.0-11.6.3.2, or 11.2.1-11.5.6, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, iWorkflow 2.1.0-2.3.0, or Enterprise Manager 3.1.1 is licensed for Appliance Mode, Admin and Resource administrator roles can by-pass BIG-IP Appliance Mode restrictions to overwrite critical system files. Attackers of high privilege level are able to overwrite critical system files which bypasses security controls in place to limit TMSH commands. This is possible with an administrator or resource administrator roles when granted TMSH. Resource administrator roles must have TMSH access in order to perform this attack.

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.

An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information.

The FastL4 virtual server in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Controller, and PEM 11.3.0 through 11.5.2 and 11.6.0 through 11.6.0 HF4, BIG-IP Edge Gateway, WebAccelerator, and WOM 11.2.1 through 11.3.0, and BIG-IP PSM 11.2.1 through 11.4.1 allows remote attackers to cause a denial of service (Traffic Management Microkernel restart) via a fragmented packet.

The Configuration utility in F5 BIG-IP systems 11.0.x, 11.1.x, 11.2.x before 11.2.1 HF16, 11.3.x, 11.4.x before 11.4.1 HF10, 11.5.x before 11.5.4 HF2, 1.6.x before 11.6.1, and 12.0.0 before HF1 allows remote administrators to read Access Policy Manager (APM) access logs via unspecified vectors.

Buffer overflow in the mcpq daemon in F5 BIG-IP systems 10.x before 10.2.4 HF12, 11.x before 11.2.1 HF15, 11.3.x, 11.4.x before 11.4.1 HF9, 11.5.x before 11.5.2 HF1, and 11.6.0 before HF4, and Enterprise Manager 2.1.0 through 2.3.0 and 3.x before 3.1.1 HF5 allows remote authenticated administrators to cause a denial of service via unspecified vectors.

The SSL profiles component in F5 BIG-IP LTM, APM, and ASM 10.0.0 through 10.2.4 and 11.0.0 through 11.5.1, AAM 11.4.0 through 11.5.1, AFM 11.3.0 through 11.5.1, Analytics 11.0.0 through 11.5.1, Edge Gateway, WebAccelerator, and WOM 10.1.0 through 10.2.4 and 11.0.0 through 11.3.0, PEM 11.3.0 through 11.6.0, and PSM 10.0.0 through 10.2.4 and 11.0.0 through 11.4.1 and BIG-IQ Cloud and Security 4.0.0 through 4.4.0 and Device 4.2.0 through 4.4.0, when using TLS 1.x before TLS 1.2, does not properly check CBC padding bytes when terminating connections, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE). NOTE: the scope of this identifier is limited to the F5 implementation only. Other vulnerable implementations should receive their own CVE ID, since this is not a vulnerability within the design of TLS 1.x itself.

In BIG-IP 14.0.0-14.0.0.2 or 13.0.0-13.1.1.1, iControl and TMSH usage by authenticated users may leak a small amount of memory when executing commands

Directory traversal vulnerability in the configuration utility in F5 BIG-IP before 12.0.0 and Enterprise Manager 3.0.0 through 3.1.1 allows remote authenticated users to access arbitrary files in the web root via unspecified vectors.

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator.
