Ivanti - Pulse Connect Secure · Listed in the CISA KEV since 2021-11-03. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2021-22900
HighCVSS 7.2KEVSummary
A vulnerability allowed multiple unrestricted uploads in Pulse Connect Secure before 9.1R11.4 that could lead to an authenticated administrator to perform a file write via a maliciously crafted archive upload in the administrator web interface.
Risk Assessment
An authenticated administrator can write arbitrary files on the device, potentially leading to further privilege escalation or system compromise.
Recommendation
Update Pulse Connect Secure to version 9.1R11.4 or later and restrict administrative access to trusted networks.
