- **CVE ID:** CVE-2026-XXXXX (Multiple vulnerabilities covering RCE and Information Disclosure)
- **CVSS Score:** Critical (Base scores typically 9.0+)
- **CWE:** Improper Neutralization of Input, Information Exposure
## Affected Systems
- **Products:** Cisco Identity Services Engine (ISE) and Cisco ISE-PIC (Passive Identity Connector)
- **Versions:**
- All releases prior to 3.3
- Release 3.3: All versions prior to 3.3 Patch 11

## Vulnerability Description
High-severity vulnerabilities in Cisco ISE and ISE-PIC allow for Remote Code Execution (RCE) and Information Disclosure. These flaws typically arise from insufficient validation of user-supplied input or improper security processing within the web-based management interface or API endpoints. An attacker could exploit these to execute arbitrary commands with administrative privileges or access sensitive system data.
## Exploitation
- **Status:** Not exploited (Current advisory indicates disclosure and patching phase; monitor vendor for "In the Wild" updates)
- **Complexity:** Low to Medium
- **Attack Vector:** Network
## Impact
- **Confidentiality:** High (Risk of sensitive data exposure)
- **Integrity:** High (Risk of unauthorized configuration changes or system takeover)
- **Availability:** High (Potential for service disruption via command execution)
## Remediation
### Patches
Cisco has released or scheduled the following software updates:
- **ISE 3.3:** Upgrade to **3.3 Patch 11**
- **ISE 3.4:** Upgrade to **3.4 Patch 6**
- **ISE 3.5:** Upgrade to **3.5 Patch 4** (Expected availability: August 2026)
### Workarounds
- No specific workarounds were provided in the summary. Users are advised to restrict network access to the ISE management interface to trusted internal networks only until patches are applied.
## Detection
- **Indicators of Compromise:** Monitor web server logs for unusual POST requests or unauthorized administrative access attempts.
- **Detection methods and tools:** Use vulnerability scanners to identify outdated ISE versions. Audit system logs for unexpected execution of system-level commands.
