Rapidly scan filesystems for Java programs potentially vulnerable to Log4Shell (CVE-2021-44228) or "that Log4j JNDI exploit" by inspecting the class paths inside files
log4shelldetect
Scans a file or folder recursively for Java programs that may be vulnerable to:
- CVE-2021-44228 (Log4Shell) (v2.0.x - v2.14.x)
- CVE-2021-45046 (v2.15.x)
- CVE-2021-45105 (v2.16.x)[^*]
[^*]: 2.12.2 detection is not available yet pending 2.12.3's release which I will need to test. 2.12.2 will appear as patched.
by inspecting the class paths inside files.
If you only want possibly vulnerable files to be printed rather than all files, run with -mode list
.
