Is Log4j still a threat
Log4j remains a threat in 2023
The highest concentration of critical findings linked to Log4j were found within the first 48 hours of the vulnerability becoming known. At the time, findings often originated in the core of an application and later findings migrated to the dependences those applications rely on.
Is Log4j safe to use now
The widespread vulnerability that first appeared in Apache Log4j in 2021 will continue to be exploited, potentially even in worse ways than we've seen to date. The more worrisome aspect of these threats is that there's a good chance they'll continue to be exploited months or years into the future.
Is Log4j fixed
Since December, most vendors have published security updates that resolve the Log4j flaw within their applications, and Apache themselves have released fixes and updated versions that remediate the vulnerability. With that being said, thousands of systems are still vulnerable today.
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.
How critical is Log4j vulnerability
The original Apache Log4j vulnerability (CVE-2021-44228), also known as Log4Shell, is a cybersecurity vulnerability on the Apache Log4j 2 Java library. This security flaw is a Remote Code Execution vulnerability (RCE) – one of the most critical security exposures.
How long has Log4j been vulnerable
The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
Is Log4j a big deal
Last week, a vulnerability was found in Log4j, an open-source logging library commonly used by apps and services across the internet. If left unfixed, attackers can break into systems, steal passwords and logins, extract data, and infect networks with malicious software.
Can we remove Log4j
Removing the Log4j related files does not affect further backup or recovery operations. BDRSuite has also developed a utility that identifies the log4j vulnerability in its installation location then removes the vulnerable file. Note: Make sure all the backups are idle when executing the utility.
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 2.17 0 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 a zero day vulnerability
Log4j is just a recent zero-day attack example. There have been many in the past. Many more will no doubt happen in the future.
How long will Log4j last
However, if past behavior is indicative of future performance, it is likely the Log4j vulnerability will crop up for years to come.
How did they fix Log4j
You can fix the Log4j vulnerability by updating Log4j to the latest version (2.15. 0 or later for CVE-2021-44228 and 2.16. 0 or later for CVE-2021-45046) and applying temporary workarounds if immediate updating is not feasible.
Does Log4j only affect Java
The vulnerability affects not only Java-based applications and services that use the library directly, but also many other popular Java components and development frameworks that rely on it.
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.
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 2.17 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.
What is the fix for Log4j
You can fix the Log4j vulnerability by updating Log4j to the latest version (2.15. 0 or later for CVE-2021-44228 and 2.16. 0 or later for CVE-2021-45046) and applying temporary workarounds if immediate updating is not feasible.
Can Log4j be removed
The log4j files can also be moved or deleted on the presentation server as a different workaround, but this stops logging for the presentation server. All config changes are still logged with the MDM and the trace logs there.

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.
