Is Log4j 2.16 still vulnerable
December 20, 2021
Log4j 2.17 has been released to address a Denial of Service (DoS) vulnerability found in v2. 16 and earlier. Log4j 2.16 and earlier does not always protect from infinite recursion in lookup evaluation, which can lead to DoS attacks. This is considered a High (7.5) vulnerability on the CVSS scale.
Is Log4j 2.17 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.
Which version of Log4j is vulnerable
Technical Details. The CVE-2021-44228 RCE vulnerability—affecting Apache's Log4j library, versions 2.0-beta9 to 2.14. 1—exists in the action the Java Naming and Directory Interface (JNDI) takes to resolve variables.
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.

2 and 2.12. 4) are vulnerable to a remote code execution attack. An attacker with access to modify the Java log4j logging configuration file can build a malicious Apache log4j2 configuration by using a JDBC Appender with a data source referencing a JNDI URI, which can execute remote code.
Is Log4j 2.12 1 vulnerable
log4j:log4j-core is a logging library for Java. Affected versions of this package are vulnerable to Remote Code Execution (RCE). Apache Log4j2 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints.
Is Log4j 2.13 3 vulnerable
log4j:log4j-core is a logging library for Java. Affected versions of this package are vulnerable to Remote Code Execution (RCE). Apache Log4j2 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints.
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 end of life
Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. CSM version 6.3.
Is Log4j version 1 vulnerable
JMSSink in Log4j 1. x is vulnerable to deserialization of untrusted data. This flaw allows a remote attacker to execute code on the server if the deployed application is configured to use JMSSink and to the attacker's JNDI LDAP endpoint. A flaw was found in the log4j 1.
Is Log4j 1.2 8 jar vulnerable
Details of CVE-2021-4104
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 12 vulnerable
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.

Is Log4j 1.2 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.
Is Log4j 1 version vulnerable
x. JMSSink in Log4j 1. x is vulnerable to deserialization of untrusted data. This flaw allows a remote attacker to execute code on the server if the deployed application is configured to use JMSSink and to the attacker's JNDI LDAP endpoint.
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 1.18 safe from log4j
All servers running 1.18. 1 and above are completely safe. For those still running version 1.18 and older, part of the necessary fix is to add specific JVM arguments to your startup command line.
