Impact
A potential remote command execution issue exists within redshift-jdbc42 versions 2.1.0.7 and below. When plugins are used with the driver, it instantiates plugin instances based on Java class names provided via the sslhostnameverifier, socketFactory, sslfactory, and sslpasswordcallback connection properties. In affected versions, the driver does not verify if a plugin class implements the expected interface before instantiatiaton. This can lead to loading of arbitrary Java classes, which a knowledgeable attacker with control over the JDBC URL can use to achieve remote code execution.
Patches
This issue is patched within redshift-jdbc-42 2.1.0.8 and above.
Workarounds
We advise customers using plugins to upgrade to redshift-jdbc42 version 2.1.0.8 or above. There are no known workarounds for this issue.
