Mchange · C3P0 · CVE-2018-20433
**Name of the Vulnerable Software and Affected Versions**
c3p0 version 0.9.5.2
**Description**
The issue allows XXE (XML External Entity) attacks in the `extractXmlConfigFromInputStream` function within `com/mchange/v2/c3p0/cfg/C3P0ConfigXmlUtils.java` during the initialization process.
**Recommendations**
For c3p0 version 0.9.5.2, consider disabling the `extractXmlConfigFromInputStream` function as a temporary workaround until a patch is available. Restrict access to the `C3P0ConfigXmlUtils` class to minimize the risk of exploitation. Avoid using external XML entities in the configuration until the issue is resolved.
