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.
