user: Unverified Password Change

Published Updated By the CyberSecBulletin desk

CVE-2025-67719 is a high-severity unverified password change vulnerability in user from Ibexa, with a CVSS 4.0 base score of 8.5 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, without any action from a user. Affected user versions: >= 5.0.0-beta1, < 5.0.4. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Ibexa is a composable end-to-end DXP (Digital Experience Platform). Versions 5.0.0-beta1 through 5.0.3 do not have password validation. During the transition from v4 to v5 an error was introduced into validation code which causes the validation of the previous password not to run as expected. This makes it possible for a logged in user to change their password in the back office without knowing the previous password. For example, if a user logs into their account and walks away without locking their workstation, an attacker could access the unattended session and change the password, therefore locking the legitimate user out. This issue is fixed in version 5.0.4.

The underlying weakness: Unverified Password Change

When setting a new password for a user, the product does not require knowledge of the original password, or using another form of authentication.

How developers prevent this class of flaw

  • When prompting for a password change, force the user to provide the original password in addition to the new password.
  • Do not use forgotten password functionality. But if you must, ensure that you are only providing information to the actual user, e.g. by using an email address or challenge question that the legitimate user already provided in the past; do not allow the current user to change this identity information until the correct password has been provided.
