Multiple vulnerabilities in the Admin portal of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to obtain sensitive information. These vulnerabilities are due to improper enforcement of administrator privilege levels for sensitive data. An attacker with read-only administrator access to the Admin portal could exploit these vulnerabilities by browsing to one of the pages that contains sensitive data. A successful exploit could allow the attacker to collect sensitive information regarding the configuration of the system. For more information about these vulnerabilities, see the Details section of this advisory.

CVSS 3.1 Base Score 6.5. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

CVSS 2.0 Base Score 4. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N).

Demo Examples

Incorrect Privilege Assignment

CWE-266

Evidence of privilege change:


               
seteuid(getuid());/* do some stuff */

               
}
// privileged code goes here, for example:// nothing to return

Incorrect Privilege Assignment

CWE-266

This application sends a special intent with a flag that allows the receiving application to read a data file for backup purposes.


               
sendBroadcast(intent);

               
}
}
stealUserData(userData);

Any malicious application can register to receive this intent. Because of the FLAG_GRANT_READ_URI_PERMISSION included with the intent, the malicious receiver code can read the user's data.
