medium Tenable Cloud Security Plugin ID 458909

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may
 perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters
 (limited local part of the email), so the attack is limited to very shorts emails (subject and little
 data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent
 from the Keycloak server. However, this action could be a precursor for more sophisticated attacks.

Solution

Update the keycloak-25 library and its related packages to version 25.0.6+e1 or later.
