CVE-2026-76433: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Cisco Cisco Identity Services Engine Software
A vulnerability in the client provisioning download feature of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to access protected files on an affected device. This vulnerability is due to insufficient validation of directory traversal character sequences in a user-supplied path when the software processes provisioning resource requests. An attacker could exploit this vulnerability by sending a crafted request to the provisioning download service. A successful exploit could allow the attacker to access protected files without authentication, potentially exposing sensitive information.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of directory traversal sequences in user-supplied paths processed by the provisioning resource requests in Cisco ISE and Cisco ISE-PIC. An attacker can send a crafted request to the provisioning download service to access protected files without authentication. The CVSS 3.1 base score is 5.3, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to integrity loss without confidentiality or availability impact.
Potential Impact
Successful exploitation allows an unauthenticated remote attacker to read protected files on the affected device, potentially exposing sensitive information. There is no impact on confidentiality or availability, and no integrity modification beyond limited scope is indicated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a patch is available, monitor vendor advisories for updates and consider restricting access to the provisioning download service if feasible.
