Senserva AI Opinion for CVE-2019-11510
This is a pre-authentication file read flaw in Ivanti Pulse Connect Secure that lets a remote attacker retrieve files, including plaintext credentials and session data, just by sending a crafted HTTPS URI to the VPN gateway. Any internet-facing Pulse Connect Secure appliance is exposed, and this one carries a maximum Severity of Critical (CVSS 10.0), a 100% EPSS score, confirmed CISA KEV listing, and documented use in ransomware campaigns. Attackers routinely harvest credentials through this bug and reuse them for follow-on intrusion even after patching, so a patch alone does not close the door.
Do this: Patch the Pulse Connect Secure appliance now, then reset all VPN account and admin credentials and revoke active sessions because captured secrets remain usable post-patch.
