Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is triggered via a maliciously crafted archive upload through the administrator web interface of Pulse Connect Secure; monitor for unusual archive file uploads (e.g., ZIP/TAR) submitted to the admin interface ↗
- →The attack results in arbitrary file write on the system; monitor for unexpected new or modified files on Pulse Connect Secure appliances following admin-interface archive uploads ↗
- ·Exploitation requires an authenticated administrator session; this is not an unauthenticated attack vector. Detection should focus on admin-authenticated sessions performing archive uploads. ↗
- ·Affected versions are Pulse Connect Secure before 9.1R11.4; ensure patched versions are confirmed before deprioritizing detections. ↗
- ·CISA issued Emergency Directive ED 21-03 specifically for Pulse Connect Secure vulnerabilities including this CVE; refer to that directive for additional organizational requirements. ↗
