Description
A vulnerability in the certificate import functionality of the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to read arbitrary files from the affected system. To exploit this vulnerability, the attacker must have valid administrative credentials.

This vulnerability is due to insufficient validation of user-supplied input by the affected feature. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to read arbitrary files from the affected device, which could contain sensitive information.

AI Analysis

Impact

A user‑supplied path in the certificate import feature of Cisco ISE’s web management interface is insufficiently validated, allowing an authenticated attacker with administrative access to retrieve any file on the device. The vulnerability can expose sensitive data such as configuration files or credentials. The weakness matches CWE‑22, indicating insecure file path handling.

Affected Systems

The affected products are Cisco Identity Services Engine and Cisco ISE Passive Identity Connector. No specific version information is provided in the advisory, so all releases of these products remain potentially vulnerable until patched.

Risk and Exploitability

The CVSS score of 4.9 indicates moderate severity, while the EPSS score of less than 1% shows a low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. Since exploitation requires valid administrative credentials, the risk is confined to environments where such privileges are granted; a successful exploit would allow attackers to read arbitrary files, potentially compromising confidential information.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Cisco ISE and ISE‑PIC to the latest patched releases as recommended by Cisco.
  • If an immediate upgrade is not feasible, restrict access to the certificate import interface to trusted administrators only and consider disabling the feature when it is not needed.
  • Enable and review audit logs for activity on the certificate import endpoint to detect potential exploitation.
