Detailsinfo

A vulnerability classified as problematic has been found in Cisco Identity Services Engine Software. Affected is an unknown functionality of the component Web-based Management Interface. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. CWE is classifying the issue as CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. This is going to have an impact on confidentiality. CVE summarizes:

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to obtain sensitive information from an affected device. This vulnerability exists because certain files lack proper data protection mechanisms. An attacker with read-only Administrator privileges could exploit this vulnerability by performing actions where the results should only be viewable to a high-privileged user. A successful exploit could allow the attacker to view passwords that are normally not visible to read-only administrators.
