CVE-2026-76432 (GCVE-0-2026-76432)

Vulnerability from cvelistv5 – Published: 2026-09-16 20:20 – Updated: 2026-09-16 20:20

Title

Cisco Identity Services Engine Arbitrary File Write Vulnerability

Summary

A vulnerability in the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker with administrative-level privileges to write arbitrary files on an affected device. This vulnerability exists because the affected software does not properly validate directory traversal character sequences in a user-supplied file path during the upload process. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to write files to an arbitrary location on the affected system.

Severity

Vulnerability from github – Published: 2026-09-16 21:32 – Updated: 2026-09-16 21:32

Details

This vulnerability exists because the affected software does not properly validate directory traversal character sequences in a user-supplied file path during the upload process. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to write files to an arbitrary location on the affected system.

Severity

4.9 (Medium)
