https://notcve.org/view.php?id=CVE-2021-22991
On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, and 12.1.x before 12.1.5.3, undisclosed requests to a virtual server may be incorrectly handled by the Traffic Management Microkernel (TMM) URI normalization, which may trigger a buffer overflow, resulting in a DoS attack. In certain situations, it may theoretically allow bypass of URL based access control or remote code execution (RCE). Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. En BIG-IP versiones 16.0.x anteriores a 16.0.1.1, versiones 15.1.x anteriores a 15.1.2.1, versiones 14.1.x anteriores a 14.1.4, versiones 13.1.x anteriores a 13.1.3.6 y versiones 12.1.x anteriores a 12.1.5.3, unas peticiones no reveladas a un servidor virtual pueden ser manejadas incorrectamente por la normalización del URI de Traffic Management Microkernel (TMM), lo que puede desencadenar un desbordamiento del búfer, resultando en un ataque de DoS. En determinadas situaciones, teóricamente puede permitir la omisión del control de acceso basado en URL o una ejecución de código remota (RCE). • https://support.f5.com/csp/article/K56715231 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

On BIG-IP version 16.0.x before 16.0.1, 15.1.x before 15.1.1, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.5, and all 12.1.x and 11.6.x versions, undisclosed endpoints in iControl REST allow for a reflected XSS attack, which could lead to a complete compromise of BIG-IP if the victim user is granted the admin role. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. En BIG-IP versiones 16.0.x anteriores a 16.0.1, versiones 15.1.x anteriores a 15.1.1, versiones 14.1.x anteriores a 14.1.3.1, versiones 13.1.x anteriores a 13.1.3.5 y todas las versiones 12.1.xy 11.6.x, endpoints no divulgados en iControl REST permiten un ataque de tipo XSS reflejado, lo que podría conllevar a un compromiso completo de BIG-IP si el usuario víctima se otorgaba el rol de administrador. Nota: No son evaluadas las versiones de software que han alcanzado End of Software Development (EoSD) • https://support.f5.com/csp/article/K87502622 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

On all versions of BIG-IP 12.1.x and 11.6.x, the original TLS protocol includes a weakness in the master secret negotiation that is mitigated by the Extended Master Secret (EMS) extension defined in RFC 7627. TLS connections that do not use EMS are vulnerable to man-in-the-middle attacks during renegotiation. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
