> > Hi @rgoers, is log4j 1.x vulnerable? > > Hi @yuezk, as far as I can tell, log4j 1.x does not support lookups. ~I also could not find any other reference to JNDI in the [log4j 1.x source code](http://svn.apache.org/viewvc/logging/log4j/trunk/). So, no guarantees but it looks like 1.x is not impacted by this vulnerability.~ **_CORRECTION_**: **log4j 1.x contains a JMS Appender which can use JNDI. So I would say that, yes, log4j 1.x is also impacted by this vulnerability** (Thank you @garydgregory for pointing this out). > > Note that log4j 1.x is [End of Life](https://logging.apache.org/log4j/1.2/) and has [other security vulnerabilities](https://www.cvedetails.com/cve/CVE-2019-17571/) that will not be fixed. ~So we do not recommend using log4j 1.x as a way to avoid this security vulnerability.~ The recommendation is to upgrade to 2.15.0. Do anyone know if I depends on the following 2: - org.apache.logging.log4j:log4j-api - org.apache.logging.log4j:log4j-to-slf4jBut without dependency on - org.apache.logging.log4j:log4j-corein this situation, is this safe from this RCE? Thanks.Edit, This may affect both log4j 2.x and log4j 1.x (see comments bellow, thanks.)reply agwa 1 hour ago \| parent \| next [–]> By the way. This only affect log4j 2.x (https://github.com/apache/logging-log4j2). the log4j 1.x (https://github.com/apache/log4j) is not affected.That's not what https://github.com/apache/logging-log4j2/pull/608#issuecomme... saysreply | | | agwa 1 hour ago \| parent \| next [–]> By the way.
