Help using command line scanner for Logj4 vulnerabilities
I found a scanner on Github that checks for Logj4 vulnerabilities that has versions for several different OSs including Linux but I am not familiar enough with Linux on Synology to run this on my own. I might figure it out if I spend a couple of hours but it would be really helpful to me, and I presume, others here if someone with the skills could respond with a short list of what to do to get this running, preferably as a one-time scheduled task or series of them if it takes that, rather than SSH'ing to the box.

So many different log4j scanner tools and scripts posted
Dell proposes Logpresso's log4j scan tool (https://github.com/logpresso/CVE-2021-44228-Scanner/releases) to mitigate vulnerabilities for various product lines, until they released actual fixes (various are still pending, so we only have the scan tool).

Well it's Log4J Patch Day. Again. (2.17 now available to fix infinite recursion bug)
Peculiarly Dell for some of their data protection products also seems to advice to use a 3rd party scan tool to mitigate against certain issues in <2.14 and 2.15 log4j using log4j-scan from Logpresso https://github.com/logpresso/CVE-2021-44228-Scanner, as far as I can see a Korean company? Would have imagined Dell would also have some developers being able to write something? But that's just me...
- So how exactly is Log4j supposed to be patched/mitigated on Windows?

Mitigating log4j in Windows?
This is fine if you only have 1 or two JAR files to deal with and you don't mind installing 7-sip to do it. However, if you have lots of JAR files, or if you don't want to install 7-zip, I created an open-source VBS script that will do it for you without needing to install any additional software. https://github.com/CrazyKidJack/Windowslog4jClassRemover

Log4j 0day being exploited
While most people that need to know probably already know enough to do what they need to do AND the information from the OP is way more complete than mine, I have not seen anyone create a Windows script that can remove the JndiLookup.class file from log4j-core JARs easily the way the zip command is able to on linux. So I thought I would post this here if anyone needs to do that... https://github.com/CrazyKidJack/Windowslog4jClassRemover
