What happened to log4j recently
| Name | Vulnerability type | Affected log4j versions |
|---|---|---|
| CVE-2021-45046 | Denial of Service (DoS) and RCE | 2.0 through 2.15.0 |
| CVE-2021-4104 | RCE | 1.2* |
| CVE-2021-45105 | Denial of Service (DoS) | 2.0-beta9 to 2.16.0 |

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.
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 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 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 Version 1.2 16 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.
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 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 2.16 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 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.
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 Version 1.2 16 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.
