In BIG-IP 11.5.1-11.5.8 and 11.6.1-11.6.3, the Configuration Utility login page may not follow best security practices when handling a malicious request.

In BIG-IP 13.0.0, 12.1.0-12.1.3.7, 11.6.1-11.6.3.2, or 11.5.1-11.5.8, the Application Acceleration Manager (AAM) wamd process used in processing of images and PDFs fails to drop group permissions when executing helper scripts.

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.

In BIG-IP 11.6.1-11.6.3.2 or 11.5.1-11.5.8, or Enterprise Manager 3.1.1, improper escaping of values in an undisclosed page of the configuration utility may result with an improper handling on the JSON response when it is injected by a malicious script via a remote cross-site scripting (XSS) attack.

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 13.0.0-13.1.1.1, 12.1.0-12.1.3.7, 11.6.1-11.6.3.2, or 11.5.1-11.5.8 or Enterprise Manager 3.1.1, when authenticated administrative users run commands in the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, restrictions on allowed commands may not be enforced.

In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.1, 12.1.0-12.1.3.6, 11.6.1-11.6.3.2, or 11.5.1-11.5.8, when processing fragmented ClientHello messages in a DTLS session TMM may corrupt memory eventually leading to a crash. Only systems offering DTLS connections via APM are impacted.

Cross-site scripting (XSS) vulnerability in F5 BIG-IP Access Policy Manager (APM) 11.5.x and 11.6.x Admin Web UI.

On BIG-IP 11.5.1-11.6.3.2, 12.1.3.4-12.1.3.7, 13.0.0 HF1-13.1.1.1, and 14.0.0-14.0.0.2, Multi-Path TCP (MPTCP) does not protect against multiple zero length DATA_FINs in the reassembly queue, which can lead to an infinite loop in some circumstances.

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 14.1.0-14.1.0.1, TMM may restart and produce a core file when validating SSL certificates in client SSL or server SSL profiles.

On BIG-IP APM 14.0.0 to 14.0.0.4, 13.0.0 to 13.1.1.3 and 12.1.0 to 12.1.3.7, a reflected cross-site scripting (XSS) vulnerability exists in the resource information page for authenticated users when a full webtop is configured on the BIG-IP APM system.

On BIG-IP LTM 13.0.0 to 13.0.1 and 12.1.0 to 12.1.3.6, under certain conditions, the TMM may consume excessive resources when processing SSL Session ID Persistence traffic.

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.

A race condition when discarding malformed packets can cause BIND to exit with an assertion failure

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.

Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user.

nginx: HTTP request smuggling in configurations with URL redirect used as error_page

NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.

0-byte record padding oracle

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then 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. If the application then behaves differently based on that in a way that is detectable to the 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. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).

On BIG-IP versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, BIG-IQ versions 7.0.0, 6.0.0-6.1.0, and 5.0.0-5.4.0, iWorkflow version 2.3.0, and Enterprise Manager version 3.1.1, authenticated users granted TMOS Shell (tmsh) privileges are able access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to access objects on the file system which would not normally be allowed.

On versions 15.0.0-15.0.1.1, 14.1.0-14.1.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, the BIG-IP APM system logs the client-session-id when a per-session policy is attached to the virtual server with debug logging enabled.
