Does the apache webserver (apache2) use log4j?

I have Apache2 2.4.38 (debian) installed on Raspberry Pi OS (64bit) and found some strange records in my log regarding CVE-2021-44228 from kryptoslogic-cve-2021-44228.com (honeypot/scanner), dataastatistics.com (offline & malicious?) and a8fvkc.dnslog.cn (I dont know what this is)

What should I do now?

  • nothing because apache2 is not affected by CVE-2021-44228
  • format everything and wait for a few days before I install a patched version
  • "check" if there are any new .class files and if there are not continue operation (and use manual patches like log4j2.formatMsgNoLookups = TRUE
  • something else
