Gateway: Improper Authentication

Published Updated By the CyberSecBulletin desk

CVE-2022-38368 is a high-severity improper authentication vulnerability in Gateway from Aviatrix, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 6.6.5712, 6.7.1376 as the first without the flaw, so updating Gateway to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.81% chance of exploitation within 30 days, higher than 58% of scored CVEs.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
