Cisco ISE EUVD-2026-81162

Exploitation requires the attacker to already hold valid Cisco ISE Administrator credentials and network reach to the web-based management interface; there is no unauthenticated path. The flaw is the absence of server-side validation of Administrator permission level, so a lower-privileged administrative account can perform a configuration change (modifying file descriptions on a specific page) reserved for higher-privileged admins. Limiting factors: valid admin authentication is mandatory (PR:L), no user interaction is needed, and the achievable impact is confined to integrity of one specific configuration element with no confidentiality or availability effect.

This is a low-priority, low-real-risk issue despite being a network-vector Cisco ISE flaw. The CVSS 3.1 base score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) is honest and narrow: integrity-only impact (I:L) with no confidentiality or availability effect, and it requires an already-authenticated attacker holding valid Administrator credentials (PR:L). The actual damage - modifying descriptions of files on one specific page due to missing server-side validation of Administrator permissions (CWE-285) - is trivial in security terms. No EPSS score, no CISA KEV listing, and no public POC are present in the provided data, so there is no signal of active or imminent exploitation. Note a metadata discrepancy: the CWE-285 improper-authorization root cause and the requirement for valid Administrator credentials make the 'Authentication Bypass' tag inaccurate - this is a privilege/authorization enforcement gap among admin tiers, not an authentication bypass (Cisco's own advisory slug 'cisco-sa-ise-auth-bypass-1' is the likely source of the loose label). Overall this is a genuine but minor authorization defect, not a mass-exploitation concern.

An attacker who already possesses valid but lower-tier ISE Administrator credentials submits a crafted HTTP request to the web-based management interface. Because the server does not validate that the account holds the required permission level, the request succeeds in altering configuration (file descriptions on a specific page) that the attacker should not be able to change. No public exploit code is identified at time of analysis.
