CVE-2022-27225 : What You Need to Know

Gradle Enterprise before 2021.4.3 has a vulnerability that stems from relying on cleartext data transmission in certain scenarios. This CVE allows attackers to capture user login sessions by exploiting a cookie setting issue in Keycloak for identity management.

Understanding CVE-2022-27225

This CVE affects Gradle Enterprise before version 2021.4.3 and involves a security issue related to cleartext data transmission and cookie handling during the sign-in process.

What is CVE-2022-27225?

Gradle Enterprise before 2021.4.3 uses Keycloak for identity management and sets browser cookies during the sign-in process. Due to a compatibility issue with older Safari versions, Keycloak sets a duplicate cookie without the Secure attribute, enabling potential session capture by attackers.

The Impact of CVE-2022-27225

The vulnerability allows attackers, capable of impersonating the Gradle Enterprise host, to capture user login sessions by tricking them into clicking an HTTP link to the server, even when HTTPS is required.

Technical Details of CVE-2022-27225

This section provides a deeper look into the vulnerability, including its description, affected systems and versions, and exploitation mechanism.
