F5 SIRT (f5sirt@f5.com CNA) via NVD
F5 is its own CVE Numbering Authority. VulniPulse ingests F5's CVEs from the NVD CNA feed (f5sirt@f5.com), each linking to its my.f5.com / support.f5.com security article. Covers BIG-IP (LTM, ASM/Advanced WAF, APM, AFM), BIG-IP Next, BIG-IQ, NGINX / NGINX Plus, F5OS and Distributed Cloud — internet-facing application-delivery and security appliances that are repeatedly mass-exploited (e.g. the CVE-2023-46747 RCE), so a patch-now enterprise audience.

When a BIG-IP LTM Client SSL profile is configured on a virtual server with SSL Forward Proxy enabled and Anonymous Diffie-Hellman (ADH) ciphers enabled, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
High [CVE-2025-48500] missing file integrity check vulnerability exists on MacOS F5 VPN browser client installer that may
A missing file integrity check vulnerability exists on MacOS F5 VPN browser client installer that may allow a local, authenticated attacker with access to the local file system to replace it with a malicious package installer. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
High [CVE-2025-46405] When Network Access is configured on a BIG-IP APM virtual server, undisclosed traffic
When Network Access is configured on a BIG-IP APM virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Medium [CVE-2025-54500] HTTP/2 implementation flaw
An HTTP/2 implementation flaw allows a denial-of-service (DoS) that uses malformed HTTP/2 control frames in order to break the max concurrent streams limit (HTTP/2 MadeYouReset Attack). Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Low [CVE-2025-53859] NGINX Open Source and NGINX Plus have a vulnerability in the ngx_mail_smtp_module that might
NGINX Open Source and NGINX Plus have a vulnerability in the ngx_mail_smtp_module that might allow an unauthenticated attacker to over-read NGINX SMTP authentication process memory; as a result, the server side may leak arbitrary bytes sent in a request to the authentication server. This issue happens during the NGINX SMTP authentication process and requires the attacker to make preparations against the target system to extract the leaked data. The issue affects NGINX only if (1) it is built with the ngx_mail_smtp_module, (2) the smtp_auth directive is configured with method "none," and (3) the authentication server returns the "Auth-Wait" response header. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
High [CVE-2025-46265] On F5OS, an improper authorization vulnerability exists where remotely authenticated users (LDAP, RADIUS, TACACS+)
On F5OS, an improper authorization vulnerability exists where remotely authenticated users (LDAP, RADIUS, TACACS+) may be authorized with higher privilege F5OS roles. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
