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.

Medium [CVE-2025-23419] NGINX: When multiple server blocks are configured to share the same IP address and port, an attacker
When multiple server blocks are configured to share the same IP address and port, an attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS Session Tickets are used and/or the SSL session cache are used in the default server and the default server is performing client certificate authentication. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. Affected product named by the advisory: NGINX.
Medium [CVE-2025-23413] When users log in through the webUI or API using local authentication, BIG-IP Next Central Manager
When users log in through the webUI or API using local authentication, BIG-IP Next Central Manager may log sensitive information in the pgaudit log files. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Low [CVE-2025-23415] insufficient verification of data authenticity vulnerability exists in BIG-IP APM Access Policy endpoint inspection that may
An insufficient verification of data authenticity vulnerability exists in BIG-IP APM Access Policy endpoint inspection that may allow an attacker to bypass endpoint inspection checks for VPN connection initiated thru BIG-IP APM browser network access VPN client for Windows, macOS and Linux. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as the victim, they can force the session to associate it with the attacker-controlled account, leading to potential misuse of the victim's session.
High [CVE-2024-45844] BIG-IP monitor functionality may allow an attacker to bypass access control restrictions, regardless of the port lockdown settings
BIG-IP monitor functionality may allow an attacker to bypass access control restrictions, regardless of the port lockdown settings. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
