A normal webserver (nginx, apache) takes care about the certs. Simple conclusion: Dont implement any certs.Īs Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. Please refer the link for additional details.Ĭerts inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application. Note that I am simply relaying this information. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities.

As of 2 version 1.2.18.2 has been released. Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). This blog post from Cloudflare also indicates the same point as from AKX.that it was introduced from Log4j 2!

‘Log4Shell’ vulnerability poses critical threat to applications using ‘ubiquitous’ Java logging package Apache Log4j Worst Apache Log4j RCE Zero day Dropped on Internet Zero-day in ubiquitous Log4j tool poses a grave threat to the Internet Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?

Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be. The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.Īm I missing something that others have identified? With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
