BIG-IP Next Central Manager: Channel Accessible by Non-Endpoint

Published Updated By the CyberSecBulletin desk

CVE-2024-32049 is a high-severity channel accessible by non-endpoint vulnerability in BIG-IP Next Central Manager from F5, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 20.1.0 as the first without the flaw, so updating BIG-IP Next Central Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.55% chance of exploitation within 30 days, which is low compared with other CVEs.

High severity with no evidence of exploitation so far.

What to do

  1. Update BIG-IP Next Central Manager to 20.1.0 or a later version.
  2. Read the advisory on my.f5.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Channel Accessible by Non-Endpoint

The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint.

How developers prevent this class of flaw

  • In order to establish secure communication between two parties, it is often important to adequately verify the identity of entities at each end of the communication channel. Always fully authenticate both ends of any communications channel.
  • Adhere to the principle of complete mediation.
  • A certificate binds an identity to a cryptographic key to authenticate a communicating party. Often, the certificate takes the encrypted form of the hash of the identity of the subject, the public key, and information such as time of issue or expiration using the issuer's private key. The certificate can be validated by deciphering the certificate with the issuer's public key. See also X.509 certificate signature chains and the PGP certification structure.
