CVE-2024-7318: Keycloak core Keycloaks's One Time Passcode (OTP) Vulnerability
MODERATECVE-2024-7318 is a MODERATE (CVSS 4.8) keycloaks's one time passcode (otp) vulnerability (CWE-324: Use of a Key Past its Expiration Date) affecting Keycloak core libraries in the Maven ecosystem. The issue involves keycloaks's one time passcode (otp) is valid longer than expiration timeseverity. Remediation is available by upgrading affected packages to version 24.0.7, 25.0.4.

How to Fix CVE-2024-7318
To remediate this vulnerability, upgrade all affected Keycloak core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-core</artifactId>
<version>24.0.7</version>
</dependency><dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-core</artifactId>
<version>25.0.4</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.keycloakHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2024-7318, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.keycloakAnalyze the terminal output to locate any version of Keycloak core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 24.0.7), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.keycloak command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-324: Use of a Key Past its Expiration Date, where the product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key. In Keycloak core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.",
