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.
What is the vulnerability of Apache Log4j version 2
Background: The Apache Log4j 2 utility is a commonly used component for logging requests. On December 9, 2021, a vulnerability was reported that could allow a system running Apache Log4j 2 version 2.15 or below to be compromised and allow an attacker to execute arbitrary code.
Is Log4j 2.16 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 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 2.15 vulnerable
The Apache Software Foundation announced a new vulnerability in Log4j – CVE-2021-45046 – on December 14th. The vulnerability as described states that Log4j 2.15. 0 can allow a local Denial of Service attack, but that impacts are limited.
Is Apache 2.4 41 vulnerable to Log4j
Apache's HTTPd (web server) isn't vulnerable – it's not written in Java, and thus it can't use Log4j. However, Log4j is incredibly popular with Java applications. Every grown-up application needs formalized logging, and Log4j provides it very well.
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 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.
Is Log4j Core 2.14 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 backwards compatible
Log4j 2 is not backwards compatible with 1. x versions, although an "adapter" is available.
Is Log4j Core 2.13 3 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.
What is Log4j Core 2.3 jar
Apache Log4j Core » 2.3
Implementation for Apache Log4J, a highly configurable logging tool that focuses on performance and low garbage generation. It has a plugin architecture that makes it extensible and supports asynchronous logging based on LMAX Disruptor.
Is Apache 2.4 54 vulnerable
Mandiant reported a Critical vulnerability in Apache HTTP Server 2.4. 54. This vulnerability could be exploited to perform a HTTP Request Smuggling attack. For a complete description of the vulnerabilities and affected systems go to CVE-2023-25690 Detail.
Is Apache 2.4 52 vulnerable
A vulnerability in Apache 2.4. 52 was discovered by James Kettle, Director of Research at PortSwigger, that could allow attackers to potentially perform HTTP Request Smuggling against backend web applications. The issue arises from the way that Apache versions 2.4.
What is Log4j 2 used for
LOG4J2 and LOG4J2 are de facto standard frameworks for logging application messages in Java. Basically, when you are developing Java applications, you include several statements that log information according to the level that you are setting.
What is Log4j-Core-2.3 jar
Apache Log4j Core » 2.3
Implementation for Apache Log4J, a highly configurable logging tool that focuses on performance and low garbage generation. It has a plugin architecture that makes it extensible and supports asynchronous logging based on LMAX Disruptor.
