What versions are affected by Log4Shell vulnerability
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 version 1 affected by Log4Shell
As log4j 1. x does NOT offer a JNDI look-up mechanism at the message level, it does NOT suffer from CVE-2021-44228. Given that log4j version 1. x is still very widely deployed, perhaps 10 times more widely than log4j 2.

| CVE-2021-4104 | RCE | 1.2* |
| CVE-2021-45105 | Denial of Service (DoS) | 2.0-beta9 to 2.16.0 |
Is Log4j version 1 affected
Applications using Log4j 1. x are only vulnerable to this attack when they use JNDI in their configuration. A separate CVE (CVE-2021-4104) has been filed for this vulnerability. To mitigate: Audit your logging configuration to ensure it has no JMSAppender configured.
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 Core 2.3 jar 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 2.16 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 2.12 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.
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.
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 2.9 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 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 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 2.17 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.
Is Log4j 2.6 2 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.
