A vulnerability was found in Apache Brooklyn up to 0.9.x. It has been rated as critical. This issue affects an unknown code block of the component SnakeYAML. The manipulation as part of a YAML Data leads to a deserialization vulnerability (Java). Using CWE to declare the problem leads to CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Apache Brooklyn uses the SnakeYAML library for parsing YAML inputs. SnakeYAML allows the use of YAML tags to indicate that SnakeYAML should unmarshal data to a Java type. In the default configuration in Brooklyn before 0.10.0, SnakeYAML will allow unmarshalling to any Java type available on the classpath. This could provide an authenticated user with a means to cause the JVM running Brooklyn to load and run Java code without detection by Brooklyn. Such code would have the privileges of the Java process running Brooklyn, including the ability to open files and network connections, and execute system commands. There is known to be a proof-of-concept exploit using this vulnerability.

The bug was discovered 12/25/2016. The weakness was shared 09/13/2017 (Website). It is possible to read the advisory at lists.apache.org. The identification of this vulnerability is CVE-2016-8744 since 10/18/2016. The attack may be initiated remotely. The requirement for exploitation is a simple authentication. The technical details are unknown and an exploit is not publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 262 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 0.10.0 eliminates this vulnerability.
