BIG-IP Edge Client: Origin Validation Error
CVE-2024-28883 is a high-severity origin validation error vulnerability in BIG-IP Edge Client 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 7.2.4.4 as the first without the flaw, so updating BIG-IP Edge Client to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.21% 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
- Update BIG-IP Edge Client to 7.2.4.4 or a later version.
- Update BIG-IP to 17.1.1 or 16.1.4.2 or 15.1.10.3, whichever matches your release line, or a later version.
- Update Big-ip Access Policy Manager to 15.1.10.3 or 16.1.4.2, whichever matches your release line, or a later version.
