CERT-FR has issued an advisory regarding multiple vulnerabilities discovered in Cisco Identity Services Engine (ISE) and ISE-PIC products. The flaws enable attackers to achieve remote arbitrary code execution and compromise data confidentiality.
Affected versions include ISE and ISE-PIC 3.4.x prior to 3.4 Patch 6, versions 3.5.x prior to 3.5 Patch 3, and versions prior to 3.3 Patch 11. Cisco has indicated that version 3.5 Patch 4, which will address both vulnerabilities, is scheduled for release in August 2026.
Organizations running affected Cisco ISE versions should consult the vendor's security bulletin for available patches and implement updates according to their maintenance windows, prioritizing internet-facing or high-value ISE deployments.
