F5: Security Vulnerabilities
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 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.

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 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 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.
