Perfektive: Improper Restriction of Excessive Authentication Attempts

Published Updated By the CyberSecBulletin desk

CVE-2025-10161 is a high-severity improper restriction of excessive authentication attempts vulnerability in Perfektive from Turkguven Software Technologies, with a CVSS 3.1 base score of 7.3 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 Version: 12574 Build: 2701 as the first without the flaw, so updating Perfektive to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Perfektive to Version: 12574 Build: 2701 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

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.
