Simple local log4j vulnerability scanner
(Written in Go because, you know, "write once, run anywhere.")
This is a simple tool that can be used to find vulnerable instances of log4j 1.x and 2.x (CVE-2019-17571, CVE-2021-44228) in installations of Java software such as web applications. JAR and WAR archives are inspected and class files that are known to be vulnerable are flagged.
This tool currently checks for known build artifacts that have been obtained through Maven. From-source rebuilds as they are done for Linux distributions may not be recognized.
$ ./log4j-vuln-scanner /path/to/app1 /path/to/app2 …
