A vulnerability was found in OpenSSL 1.0.2. When an application encounters a fatal protocol error and then calls SSLshutdown() twice, OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. This difference in behaviour can be detected by a remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Also the application must call SSLshutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). AEAD ciphersuites are not impacted. This issue does not impact OpenSSL 1.1.1 or 1.1.0.

A cross-site scripting vulnerability was discovered in bootstrap. If an attacker could control the data given to tooltip or popover, they could inject HTML or Javascript into the rendered page when tooltip or popover events fired.
On BIG-IP 15.0.0-15.0.1.1, 14.1.0-14.1.2.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.6.0-11.6.5.1, the tmm crashes under certain circumstances when using the connector profile if a specific sequence of connections are made.
Under certain conditions, on F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.1, or 11.6.1 HF2-11.6.3.1, virtual servers configured with Client SSL or Server SSL profiles which make use of network hardware security module (HSM) functionality are exposed and impacted by this issue.
A local file vulnerability exists in the F5 BIG-IP Configuration utility on versions 13.0.0, 12.1.0-12.1.2, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1 that exposes files containing F5-provided data only and do not include any configuration data, proxied traffic, or other potentially sensitive customer data.
On F5 BIG-IP 12.1.0-12.1.3.1, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, carefully crafted URLs can be used to reflect arbitrary content into GeoIP lookup responses, potentially exposing clients to XSS.
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.
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.
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.
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.
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.
A flaw was found in computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.
This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition

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.
On BIG-IP 11.5.1-11.5.8, 11.6.1-11.6.3, 12.1.0-12.1.3.6, 13.0.0-13.1.1.1, and 14.0.0-14.0.0.2, under certain conditions, hardware systems with a High-Speed Bridge and using non-default Layer 2 forwarding configurations may experience a lockup of the High-Speed Bridge.
On BIG-IP 11.5.1-11.6.3.4, 12.1.0-12.1.3.7, 13.0.0-13.1.1.3, and 14.0.0-14.0.0.2, when processing certain SNMP requests with a request-id of 0, the snmpd process may leak a small amount of memory.
In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.1-11.6.3.2, or 11.5.1-11.5.8 or Enterprise Manager 3.1.1, malformed requests to the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, may lead to disruption of TMUI services. This attack requires an authenticated user with any role (other than the No Access role). The No Access user role cannot login and does not have the access level to perform the attack.
In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.3, 12.1.0-12.1.3.7, 11.6.1-11.6.3.2, or 11.5.1-11.5.8, when remote authentication is enabled for administrative users and all external users are granted the "guest" role, unsanitized values can be reflected to the client via the login page. This can lead to a cross-site scripting attack against unauthenticated clients.
On BIG-IP 11.5.1-11.5.4, 11.6.1, and 12.1.0, a virtual server configured with a Client SSL profile may be vulnerable to a chosen ciphertext attack against CBC ciphers. When exploited, this may result in plaintext recovery of encrypted messages through a man-in-the-middle (MITM) attack, despite the attacker not having gained access to the server's private key itself. (CVE-2019-6593 also known as Zombie POODLE and GOLDENDOODLE.)
On BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.3, 12.1.0-12.1.3.7, and 11.6.0-11.6.3.2, a reflected Cross Site Scripting (XSS) vulnerability is present in an undisclosed page of the BIG-IP TMUI (Traffic Management User Interface) also known as the BIG-IP configuration utility.
On F5 BIG-IP 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, when multiple route domains are configured, undisclosed requests to big3d can cause an increase in CPU resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
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 directory traversal vulnerability exists in iControl SOAP that allows an authenticated attacker with at least guest role privileges to read wsdl files in the BIG-IP file system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
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, directory traversal vulnerabilities exist in undisclosed iControl REST endpoints and TMOS Shell (tmsh) commands in F5 BIG-IP Guided Configuration, which may allow an authenticated attacker with at least resource administrator role privileges to read arbitrary files. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
On F5 BIG-IP 13.0.0-13.1.1.1 and 12.1.0-12.1.3.6, a reflected Cross-Site Scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an authenticated user to execute JavaScript for the currently logged-in user.
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.
On all versions of 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x of F5 BIG-IP (fixed in 17.0.0), a cross-site request forgery (CSRF) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility. This vulnerability allows an attacker to run a limited set of commands: ping, traceroute, and WOM diagnostics. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.
On F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.0-11.6.3.1, or 11.2.1-11.5.6 a domain name cached within the DNS Cache of TMM may continue to be resolved by the cache even after the parent server revokes the record, if the DNS Cache is receiving a stream of requests for the cached name.
On F5 BIG-IP 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, and F5 BIG-IQ Centralized Management all versions of 8.x and 7.x, when an IPv6 self IP address is configured and the ipv6.strictcompliance database key is enabled (disabled by default) on a BIG-IP system, undisclosed packets may cause decreased performance. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
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, and F5 BIG-IQ Centralized Management all versions of 8.x and 7.x, an authenticated, high-privileged attacker with no bash access may be able to access Certificate and Key files using Secure Copy (SCP) protocol from a remote system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and WebSafe software version 13.0.0, 12.1.0 - 12.1.2 and 11.5.1 - 11.6.1, an undisclosed sequence of packets, sourced from an adjacent network may cause TMM to crash.
