Plextrac: Improper Restriction of Excessive Authentication Attempts
CVE-2022-37145 is a high-severity improper restriction of excessive authentication attempts vulnerability in Plextrac, with a CVSS 3.1 base score of 7.5 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 1.17.0 as the first without the flaw, so updating Plextrac to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.05% chance of exploitation within 30 days, higher than 65% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Plextrac to 1.17.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The PlexTrac platform prior to version 1.17.0 does not restrict excessive authentication attempts for accounts configured to use the PlexTrac authentication provider. An unauthenticated remote attacker could perform a bruteforce attack on the login page with no time or attempt limitation in an attempt to obtain valid credentials for the platform users configured to use the PlexTrac authentication provider.

The underlying weakness: Improper Restriction of Excessive Authentication Attempts
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.
How developers prevent this class of flaw
- Common protection mechanisms include: Disconnecting the user after a small number of failed attempts Implementing a timeout Locking out a targeted account Requiring a computational task on the user's part.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
