Description
A vulnerability in the web-based management interface of Cisco Identify Services Engine (ISE) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device.

This vulnerability is due to the lack of server-side validation of Administrator permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to modify descriptions of files on a specific page. To exploit this vulnerability, an attacker would need valid Administrator credentials.

AI Analysis

Impact

A missing server‑side validation check in the web‑based management interface of Cisco Identity Services Engine (ISE) allows an authenticated attacker with administrative credentials to submit crafted HTTP requests that modify configuration settings. The flaw enables intentional alteration of file descriptions on a specific page, effectively granting the attacker the ability to change parts of the device configuration beyond what standard permissions should allow.

Affected Systems

The vulnerability affects Cisco Identity Services Engine Software. No specific version information is provided in the advisory.

Risk and Exploitability

The CVSS score of 4.3 indicates moderate severity, while the EPSS score of less than 1% reflects a very low likelihood of exploitation. The flaw is not listed in the CISA KEV catalog. Exploitation requires an attacker to be authenticated as an administrator and to send a crafted HTTP request to the ISE web interface; server‑side validation of administrator permissions is absent, allowing configuration changes that should have been restricted.

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the security advisory that addresses the lack of server‑side validation for administrator permissions.
  • Limit the web‑based management interface to trusted networks or VPN access to reduce exposure.
  • Verify that only authorized personnel hold administrative credentials; consider implementing multi‑factor authentication for admin accounts.
