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 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 2.16 0 vulnerable
Vulnerability Details
DESCRIPTION: Apache Log4j is vulnerable to a denial of service, caused by the failure to protect from uncontrolled recursion from self-referential lookups.
Is Log4j 1.2 17 jar affected
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. This affects Log4j versions up to 1.2 up to 1.2. 17.
Is Log4j 2.7 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 2.12 4 safe
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 Core 2.17 0 jar vulnerable
Apache Log4j2 versions from 2.0-beta7 to 2.17. 0 (excluding security fix releases 2.3. 2 and 2.12. 4) are vulnerable to a remote code execution attack.
Is Log4j 2.16 safe
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 2.3 vulnerable
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 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.
What replaces Log4j 1.2 17 jar
By drop-in, we mean that you can replace log4j. jar with reload4j. jar in your build with no source code changes, no recompilation, nor rebuild being necessary. The reload4j project offers a clear and easy migration path for the thousands of users who have an urgent need to fix vulnerabilities in log4j 1.2.
Is Log4j 1.2 6 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. This affects Log4j versions up to 1.2 up to 1.2. 17.

Which log4j2 version is safe
x, the best advice us to use the most recent version. At the time of writing this (2021-03-14), https://logging.apache.org/log4j/2.x/security.html says that log4j 2.3. 2 is safe if you are running the code on a Java 6 JVM. But if you intend to run on a more recent JVM, the latest security patch is advisable.
Is 1.18 1 safe from Log4j
Is My Server Safe All servers running 1.18. 1 and above are completely safe.
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 version 1 end of life
It is part of the Apache Logging Services, a project of the Apache Software Foundation. Log4j 1 reached End-Of-Life on August 2015.
Is Log4j-Core-2.17 0 jar vulnerable
The Severity was also changed from moderate to critical. Log4j version 2.17. 0 was released on December 18th in response to another Log4j vulnerability. Labeled CVE-2021-45105, the newest security hole is a Denial-of-Service vulnerability with a CVSS score of 7.5 and is rated as High by Apache.
Is Log4j 2 safe
2 is safe if you are running the code on a Java 6 JVM. But if you intend to run on a more recent JVM, the latest security patch is advisable. See https://www.petefreitag.com/item/926.cfm for a list of recent log4j 1. x and 2.
Is Log4j 1 affected by vulnerability
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.
Is Log4j 1 still supported
Log4j 1. x has reached End of Life in 2015 and is no longer supported.
Which LOG4J2 version is safe
x, the best advice us to use the most recent version. At the time of writing this (2021-03-14), https://logging.apache.org/log4j/2.x/security.html says that log4j 2.3. 2 is safe if you are running the code on a Java 6 JVM. But if you intend to run on a more recent JVM, the latest security patch is advisable.
Is Log4j 1 Secure
Although this is a secure functionality, the Log4j flaw allows an attacker to input their own JNDI lookups, where they then direct the server to their fake LDAP server.
Is Log4j Core 2.11 1 jar vulnerable
log4j:log4j-core is a logging library for Java. Affected versions of this package are vulnerable to Denial of Service (DoS). Does not protect against uncontrolled recursion from self-referential lookups.
