unified_threat_management: Improper Authentication
CVE-2024-39340 is a high-severity improper authentication vulnerability in unified_threat_management from Securepoint, with a CVSS 3.1 base score of 8.8 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 versions 12.6.5, 12.7.1 as the first without the flaw, so updating unified_threat_management to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.91% chance of exploitation within 30 days, higher than 61% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update unified_threat_management to 12.6.5 or 12.7.1, whichever matches your release line, 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.

Official description
The authentication system of Securepoint UTM mishandles OTP keys. This allows the bypassing of second-factor verification (when OTP is enabled) in both the administration web interface and the user portal. Affected versions include UTM 11.5 through 12.6.4 and Reseller Preview 12.7.0. The issue has been fixed in UTM 12.6.5 and 12.7.1.
