CVE-2016-8744

High

Published: 13/09/2017(UTC)Translated: 15/06/2026(UTC)NVD NIST

Summary

Apache Brooklyn before version 0.10.0 uses the SnakeYAML library for parsing YAML data, allowing deserialization to any Java type. In the default configuration, an authenticated user can exploit this vulnerability to execute unauthorized Java code in the context of the Brooklyn process.

Risk Assessment

This vulnerability may lead to unauthorized system access, allowing an attacker to open files, establish network connections, and execute system commands with the privileges of the Brooklyn process.

Recommendation

It is recommended to upgrade Apache Brooklyn to version 0.10.0 or later to mitigate this vulnerability. Additionally, consider restricting access to YAML deserialization functions to trusted users only.

Other vulnerabilities in Apache Brooklyn

CVE-2016-8737High
In Apache Brooklyn before version 0.10.0, the REST server is vulnerable to cross-site request forgery (CSRF), which could allow a malicious website to execute the attacker's commands as the user if clicked while logged in.

Original NVD description (English source)

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.
