Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in Cisco Identity Services Engine and Cisco Identity Services Engine-Passive Identity Connector could permit an unauthenticated, remote attacker to execute arbitrary code with root privileges on the operating system. This flaw stems from insufficient validation of user-supplied input within a specific API. Exploitation could lead to significant business risk by allowing an attacker to gain complete control over affected devices.
- Vulnerable API component
- Insufficient input validation
- Unauthorized root-level access
Attack Path
How an attacker could exploit the issue
A vulnerability exists in a specific API within Cisco Identity Services Engine and Cisco ISE-PIC. This flaw could enable an unauthenticated, remote attacker to execute arbitrary code with root privileges on the affected system. Exploitation does not require any valid credentials.
- External network exposure required.
- Attacker submits a crafted API request.
- Gains root privileges on the device.
Live Threat
Current exploitation, exposure, and threat context
A vulnerability exists within specific APIs of Cisco Identity Services Engine and Cisco Identity Services Engine-PIC. This flaw could enable an unauthenticated, remote attacker to execute arbitrary code on the underlying operating system with root privileges. Exploitation is possible by sending a specially crafted API request, and the attacker would not need valid credentials. The business risk is high due to the potential for complete system compromise.
- Likely attacker skill level: Low
- Required access or conditions: Network access
- Business risk or urgency: High
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
A critical vulnerability exists within Cisco Identity Services Engine (ISE) and Cisco ISE-PIC API functions. This issue could enable an unauthenticated, remote attacker to execute arbitrary code with root privileges on the underlying operating system without needing any credentials. The vulnerability stems from insufficient validation of user-supplied input, which an attacker can exploit by sending a specifically crafted API request.
- Identify exposed Cisco ISE assets.
- Reduce exposure or isolate affected systems.
- Apply vendor fixes and validate.
