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, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, a malicious HTTP response to an Advanced WAF/BIG-IP ASM virtual server with Login Page configured in its policy may trigger a buffer overflow, resulting in a DoS attack. In certain situations, it may allow remote code execution (RCE), leading to complete system compromise. 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, versiones 12.1.x anteriores a 12.1.5.3 y versiones 11.6.x anteriores a 11.6.5.3, una respuesta HTTP maliciosa para un servidor virtual de Advanced WAF o ASM BIG-IP con la página de inicio de sesión configurada en su política puede desencadenar un desbordamiento del búfer, resultando en un ataque de DoS. En determinadas situaciones, puede permitir una ejecución de código remota (RCE), conllevando a un compromiso completo del sistema. • https://support.f5.com/csp/article/K52510511 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

On BIG-IP Advanced WAF and ASM version 15.1.x before 15.1.0.2, 15.0.x before 15.0.1.4, 14.1.x before 14.1.2.5, 13.1.x before 13.1.3.4, 12.1.x before 12.1.5.2, and 11.6.x before 11.6.5.2, when receiving a unauthenticated client request with a maliciously crafted URI, a BIG-IP Advanced WAF or ASM virtual server configured with a DoS profile with Proactive Bot Defense (versions prior to 14.1.0), or a Bot Defense profile (versions 14.1.0 and later), may subject clients and web servers to Open Redirection attacks. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. En BIG-IP Advanced WAF y ASM versiones 15.1.x anteriores a 15.1.0.2, versiones 15.0.x anteriores a 15.0.1.4, versiones 14.1.x anteriores a 14.1.2.5, versiones 13.1.x anteriores a 13.1.3.4, versiones 12.1.x anteriores a 12.1.5.2 y versiones 11.6.x anteriores a 11.6.5.2, cuando se recibe una petición de cliente no autenticado con un URI diseñado maliciosamente, un servidor virtual de BIG-IP Advanced WAF o ASM configurado con un perfil DoS con Proactive Bot Defense (versiones anteriores a 14.1.0) o un perfil Bot Defense (versiones 14.1.0 y posteriores) puede someter a los clientes y servidores web a ataques de redireccionamiento abierto. Nota: No se evalúan las versiones de software que han alcanzado End of Software Development (EoSD) • https://support.f5.com/csp/article/K33440533 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

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.

On BIG-IP APM version 16.0.x before 16.0.1.1, under certain conditions, when processing VPN traffic with APM, TMM consumes excessive memory. A malicious, authenticated VPN user may abuse this to perform a DoS attack against the APM. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. En BIG-IP APM versiones 16.0.x anteriores a 16.0.1.1, bajo determinadas condiciones, al procesar tráfico VPN con APM, TMM consume memoria excesiva. Un usuario de VPN autenticado y malicioso puede abusar de esto para llevar a cabo un ataque de DoS contra APM. • https://support.f5.com/csp/article/K88162221 • CWE-400: Uncontrolled Resource Consumption •
