BIG-IP Edge Client: Missing Support for Integrity Check
CVE-2025-48500 is a high-severity missing support for integrity check vulnerability in BIG-IP Edge Client from F5, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 7.2.5.3 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 0.13% 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 7.2.5.3 or a later version.
- Update Big-ip Access Policy Manager to 15.1.10.8 or 16.1.6.1 or 17.1.3 or 17.5.1.3, whichever matches your release line, or a later version.
- Read the advisory on my.f5.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
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.

The underlying weakness: Missing Support for Integrity Check
The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum.
How developers prevent this class of flaw
- Add an appropriately sized checksum to the protocol, ensuring that data received may be simply validated before it is parsed and used.
- Ensure that the checksums present in the protocol design are properly implemented and added to each message before it is sent.
