CISCO Security Advisory
Published Date: May 6, 2026
CVE: CVE-2026-20189
Advisory Summary
A medium-severity vulnerability (CVE-2026-20189) has been identified in Cisco Prime Infrastructure, specifically affecting the log file download functionality. The root cause is insufficient authorization checks on the download service API, which could allow an authenticated remote attacker to exploit crafted URL requests and download arbitrary, sensitive log files stored on the server.
- Exploitation requires valid credentials to access the web-based management interface, limiting risk to authenticated users.
- There are no available workarounds or mitigations apart from applying the security updates provided by Cisco.
- This vulnerability represents a data exposure risk that could lead to unauthorized disclosure of sensitive infrastructure logs.
- Network administrators should prioritize deploying the Cisco-issued software updates to remediate this vulnerability promptly.
- Review user access policies and credentials for the Cisco Prime Infrastructure management interface to minimize potential internal threats.
- Monitor audit logs for suspicious download activity related to log files until the patch is applied.
This vulnerability underscores the critical need for robust authorization mechanisms around API endpoints in IT infrastructure management tools. Timely patch implementation is essential to maintain the integrity and confidentiality of infrastructure data.
