CVE-2016-6814: When an application with unsupported Codehaus versions of Groovy from 1.7.0 to 2.4.3, Apache Groovy 2.4.4 t...

Security readout for executives and security teams

This flaw can let malicious serialized data trigger code execution in Java applications that carry vulnerable Groovy versions. Business risk depends on whether the application deserializes data an attacker can influence. Systems that do not use Java serialization with Groovy on the classpath are less exposed. Look for Java applications, middleware, or packaged vendor products with vulnerable Groovy libraries on the classpath and Java serialization enabled for server communication or local data storage. Treat this as high priority where Groovy and Java serialization intersect, especially in externally reachable services. Defer only after confirming the affected library versions are absent or deserialization input is trusted and isolated. Mitigation focus: Identify and remove vulnerable Groovy versions from application classpaths.; Update Groovy or vendor-provided packages according to Apache, Red Hat, Gentoo, or Oracle guidance.; Avoid deserializing untrusted Java objects where possible..
