Log4shell

On December the 9th, 2021, Apache published a severe vulnerability called Log4shell (and other Log4j-related vulnerabilities).

How to scan your services quickly, basically with log4j-scan from fullhunt, but using cisagov:

git clone https://github.com/cisagov/log4j-scanner.git
cd log4-scanner/

The easiest way is to create a list of all URLs you want to check:

nano urls.txt

https://digitalprivacy.diy
https://meet.digitalprivacy.diy
https://searx.digitalprivacy.diy

python log4j-scan.py -l urls.txt --waf-bypass --run-all-tests

or just a url

python log4j-scan.py -u https://digitalprivacy.diy --waf-bypass --run-all-tests
