Administrator-level arbitrary file read via crafted ERS request
Published Sep 7, 2023 · Updated Oct 23, 2024
Improper privilege management in Cisco Identity Services Engine's ERS API allows remote authenticated users to read arbitrary OS files. Cisco has not disclosed the specific ERS endpoint or authorization decision that mishandles the crafted request. Exploitation requires Administrator-level privileges and ERS enabled, and the consequence is limited to reading sensitive operating-system files.
