Eric Everman commented on LOG4J2-3293:
--------------------------------------

Could someone please clarify this detail in the [vulnerability related to this issue|https://logging.apache.org/log4j/2.x/security.html]:
{quote}vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file
{quote}
I _think_ what this means to say is that a JDBC appender must be configured to be vulnerable to a RCE attack.  As it currently reads, it sounds like a RCE attacker needs access to the configuration file, which would not really be an RCE attack.

> JDBC Appender should use JndiManager when accessing JNDI. JNDI access should be controlled via a system property.
> Related to [CVE-2021-44832|https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44832] where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.
> Fixed in [https://github.com/apache/logging-log4j2/commit/05db5f9527254632b59aed2a1d78a32c5ab74f16]
