Multiple vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an unauthenticated, remote attacker to issue commands on the underlying operating system as the root user. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. Note: Since the publication of version 1.0 of this advisory, improved fixed releases have become available. Cisco recommends upgrading to an enhanced fixed release as follows: If Cisco ISE is running Release 3.4 Patch 2, no further action is necessary. If Cisco ISE is running Release 3.3 Patch 6, additional fixes are available in Release 3.3 Patch 7, and the device must be upgraded. If Cisco ISE has either hot patch ise-apply-CSCwo99449_3.3.0.430_patch4-SPA.tar.gz or hot patch ise-apply-CSCwo99449_3.4.0.608_patch1-SPA.tar.gz installed, Cisco recommends upgrading to Release 3.3 Patch 7 or Release 3.4 Patch 2. The hot patches did not address CVE-2025-20337 and have been deferred from CCO.

A vulnerability in an internal API of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to upload arbitrary files to an affected device and then execute those files on the underlying operating system as root. This vulnerability is due a lack of file validation checks that would prevent uploaded files from being placed in privileged directories on an affected system. An attacker could exploit this vulnerability by uploading a crafted file to the affected device. A successful exploit could allow the attacker to store malicious files on the affected system and then execute arbitrary code or obtain root privileges on the system.
