HIGH 8.8

DescriptionCVE.org

JBoss Seam 2 (jboss-seam2), as used in JBoss Enterprise Application Platform 4.3.0 for Red Hat Linux, does not properly sanitize inputs for JBoss Expression Language (EL) expressions, which allows remote attackers to execute arbitrary code via a crafted URL. NOTE: this is only a vulnerability when the Java Security Manager is not properly configured.

AnalysisAI

JBoss Seam 2 in Red Hat JBoss EAP 4.3.0 fails to sanitize JBoss Expression Language inputs, allowing remote attackers to achieve arbitrary code execution via crafted URL parameters when the Java Security Manager is misconfigured.

Technical ContextAI

The CWE-917 EL injection flaw allows attackers to inject arbitrary JBoss Expression Language expressions via URL parameters. These expressions are evaluated server-side, and when the Java Security Manager is absent or misconfigured, they can invoke arbitrary Java methods including Runtime.exec().
