FileZ Client: Improper Validation of Specified Type of Input
CVE-2024-8058 is a high-severity improper validation of specified type of input vulnerability in FileZ Client from Lenovo, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 9.8.6.0 as the first without the flaw, so updating FileZ Client to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% 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 FileZ Client to 9.8.6.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
