WSO2 Enterprise Integrator: Protection Mechanism Failure

Published Updated By the CyberSecBulletin desk

CVE-2024-6832 is a high-severity protection mechanism failure vulnerability in WSO2 Enterprise Integrator from WSO2, 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 6.6.0.229 as the first without the flaw, so updating WSO2 Enterprise Integrator to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.41% 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 WSO2 Enterprise Integrator to 6.6.0.229 or a later version.
  2. Update WSO2 API Control Plane to 4.5.0.40 or 4.6.0.4 or 4.6.0.5, whichever matches your release line, or a later version.
  3. Update WSO2 Traffic Manager to 4.5.0.38 or 4.6.0.4 or 4.6.0.5, whichever matches your release line, or a later version.
  4. Read the advisory on security.docs.wso2.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The account locking mechanism fails to trigger when secondary user stores are inaccessible. The software does not maintain a consistent state for account locking if it cannot reach all configured user stores, allowing an attacker to repeatedly attempt authentication with invalid credentials without triggering the lockout mechanism for users within active stores. When the account locking mechanism is bypassed due to the inaccessibility of secondary user stores, users in accessible user stores are left vulnerable to brute force attacks. A malicious actor can exploit this by attempting numerous invalid password combinations against a user account without the expected account lockout consequence.
