Does Log4j 1.2 17 have vulnerability
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data.
Does Log4j 1.2 have vulnerability
JMSAppender, in log4j 1.2 version, is vulnerable to deserialization of untrusted data if the attacker has the 'write' permissions to the log4j configuration.
Is Log4j 1.2 affected by vulnerability
JMSAppender, in log4j 1.2 version, is vulnerable to deserialization of untrusted data if the attacker has the 'write' permissions to the log4j configuration.
What is the vulnerability of Log4j 1.2 8
Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender.
Is Log4j 1.2 17 Safe
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data.
Does Log4j 1.2 14 have vulnerability
Affected versions of this package are vulnerable to Deserialization of Untrusted Data. JMSSink in all versions of Log4j 1. x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to.
Is Log4j 2.17 0 vulnerable
3 or 2.17. 0: from these versions onwards, only the JAVA protocol is supported in JNDI connections. Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using only the log4j-api JAR file without the log4j-core JAR file are not impacted by this vulnerability.
Is Log4j 1.2 17 vulnerable or not

Is log4j 2.17 0 vulnerable
3 or 2.17. 0: from these versions onwards, only the JAVA protocol is supported in JNDI connections. Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using only the log4j-api JAR file without the log4j-core JAR file are not impacted by this vulnerability.
Does log4j 1.2 14 have vulnerability
Affected versions of this package are vulnerable to Deserialization of Untrusted Data. JMSSink in all versions of Log4j 1. x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to.
Is Log4j 1.2 7 vulnerable
JMSAppender, in log4j 1.2 version, is vulnerable to deserialization of untrusted data if the attacker has the 'write' permissions to the log4j configuration.
Is Log4j 2.17 1 safe
1 can probably wait. A number of security professionals say that the latest vulnerability in Apache Log4j, disclosed on Tuesday, does not pose an increased security risk for the majority of organizations. As a result, for many organizations that have already patched to version 2.17.
