Impact: CVSS base score 7.5 CVSS impact score 6.4 CVSS exploitability score 10.0 confidentialityImpact PARTIAL integrityImpact PARTIAL availabilityImpact PARTIAL Details: Ease of Attack:
This event is triggered when a specially crafted cookie containing java code injection is sent to a vulnerable Apache Struts server, allowing manipulation of the ClassLoader due to inadequate validation of the cookie.
