Forensic triage

What to do now

Find every instance of Endpoint Manager Mobile (EPMM) you run, including the forgotten ones, and check its version against the vendor advisory.
Apply the vendor's fix or mitigation, before August 21, 2023 if you are bound by CISA's deadline, sooner if it faces the internet.
Assume it was tried against you already: look for signs of exploitation from the date it was added, not from the day you patched.
Until every instance is patched, block the attack at the edge: a WAF in blocking mode stops path traversal attempts.
