MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires an authenticated Cisco ISE administrator account that has been granted management rights over network users; the attacker then uses the user-export feature, whose underlying files lack proper authorization enforcement, to read data for users outside their assigned security group. The key limiting factors are: valid administrative credentials (PR:H), possession of user-management delegation, and access to the web-based management interface - this is not exploitable by unauthenticated or read-only/unprivileged users. The impact is confined to disclosure of user data (including normally-hidden passwords); there is no integrity or availability effect. Affects ISE 3.1 through 3.5 (and ISE-PIC equivalents) prior to fixed patch levels. |
| Impact | This is a genuine but tightly-gated confidentiality issue, not a broad emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N, base 4.9 Medium) tells the real story: while network-reachable and low-complexity, exploitation requires PR:H - specifically an authenticated administrator who already holds management rights over network users. The C:H rating reflects that the leaked data includes user passwords normally hidden from administrators, but I:N/A:N confirm there is no integrity or availability impact; this is a pure information-disclosure/authorization flaw (CWE-863). No EPSS score, no CISA KEV listing, and no public POC were provided, so the current status is 'no public exploit identified at time of analysis.' The absence of KEV/EPSS combined with the high privilege requirement means this is a lower-priority patch item than the unauthenticated ISE flaws in the same product family (e.g. the unauthenticated SQLi CVE-2026-20247). One data-quality caveat: the 'Authentication Bypass' tag conflicts with the actual mechanism - this is an authorization (CWE-863) failure exploited BY an authenticated admin, not an authentication bypass. Overall: a real but narrow insider/privilege-boundary risk, appropriately scored Medium. |
| Exploit ScenarioDerived | A lower-tier Cisco ISE administrator who has been delegated management rights over one set of network users abuses a user-export function whose backing files lack proper authorization checks. By exporting users, the attacker retrieves sensitive data - including user passwords - for accounts outside their assigned security group, data that should be invisible to them. No public exploit code is currently identified; exploitation requires existing administrative access to the ISE web UI. |

Alert meAnalysisAIv1 – Sep 16, 2026
Authenticated Cisco Identity Services Engine (ISE) administrators who hold delegated management rights over network users can abuse the platform's user-export function to read records - including normally hidden user passwords - belonging to security groups they are not assigned to, because the files backing that export lack proper authorization enforcement. The issue affects ISE 3.1 through 3.5 (and equivalent ISE-PIC deployments) at the patch levels enumerated in the Cisco advisory, and requires a valid high-privileged account with user-management delegation plus access to the web-based management interface; unauthenticated, read-only, or otherwise unprivileged users cannot trigger it. Impact is limited to confidentiality (C:H, no integrity or availability effect, CVSS 4.9 / PR:H), and no public exploit code or confirmed active exploitation was identified at time of analysis. This is a genuine but tightly-gated confidentiality issue rather than a broad emergency, and should be prioritized behind perimeter-critical exposures while still being remediated promptly because the disclosed data includes credentials.
RemediationAI
Apply the fixed software release identified in Cisco Security Advisory cisco-sa-ise-multi-vuln-kWLeNnRD (https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-multi-vuln-kWLeNnRD), which is the authoritative source for the patched patch levels corresponding to each affected ISE 3.1-3.5 train - Cisco patch numbering differs per train, so verify the exact target build for your branch before upgrading rather than assuming a generic latest version; the provided data does not enumerate specific fix build numbers, so treat the advisory as the definitive version reference. Until the upgrade is validated in production, reduce the attack surface by auditing and revoking delegated 'network user management' rights from administrators who do not strictly need them, since the exploit path depends on that delegation, and by enforcing least-privilege RBAC so no single role combines user-export capability with group-scoped visibility; the trade-off is slower administrative workflows for helpdesk and onboarding teams. Restrict access to the ISE web management interface to dedicated management VLANs or jump hosts with ACLs and MFA so that a compromised low-tier account cannot easily reach the export endpoint, and enable detailed audit logging/alerting on user-export actions to detect abnormal or bulk exports. Treat any exported user passwords as potentially compromised: rotate or force-reset credentials whose scope an administrator could have exported, and monitor for credential-reuse authentication attempts against other systems. If user export is not a required business function, disabling or tightly controlling that workflow removes the exploit trigger entirely, at the cost of losing bulk account reporting.

Technical ContextAI · show details
Cisco ISE is the policy and identity platform that authenticates and authorizes endpoints and users on enterprise networks, and its web-based management interface exposes administrative workflows - including bulk export of internal and guest/network user accounts - to delegated administrators. The flaw is classified as CWE-863 (Incorrect Authorization): the export routine serves files that should be filtered by the requester's assigned security group, but the authorization check on those files is missing or incomplete, so a delegated administrator's scope is effectively bypassed. The CVSS 3.1 vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N confirms the attack is network-reachable (management UI over HTTPS), low complexity, requires high privileges (administrative credentials plus delegation of user-management rights), needs no user interaction, and yields only high confidentiality loss with no scope change, integrity, or availability impact. The CPE string cpe:2.3:a:cisco:cisco_identity_services_engine_software:*:*:*:*:*:*:*:* with a wildcard version indicates the identifier covers the ISE software product line broadly rather than a single build, consistent with the EUVD enumeration spanning many 3.1-3.5 patch levels. Notably, the data at risk includes passwords that are normally masked even from legitimate administrators, meaning the leaked material could support credential reuse attacks and lateral movement if accounts are shared across systems.

DescriptionCVE.org
A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to obtain sensitive information from network users that are outside the security group that the attacker is assigned to.
This vulnerability exists because certain files lack proper authorization enforcement. An attacker with administrative privileges and management rights over network users could exploit this vulnerability by exporting the users. A successful exploit could allow the attacker to view passwords that are normally not visible to administrators.
