Horizon Alert
Summary of the vulnerability and why it matters
Certain Cisco Unified Communications products are vulnerable due to improper handling of user-supplied input in HTTP requests. This flaw could permit an unauthenticated, remote attacker to execute arbitrary commands, potentially leading to unauthorized operating system access and elevated privileges. Such a compromise could impact the confidentiality, integrity, and availability of communication systems.
- Vulnerable Cisco Unified Communications products
- Improper input validation in HTTP requests
- Unauthorized operating system access and privilege escalation
Attack Path
How an attacker could exploit the issue
The vulnerability affects Cisco Unified Communications Manager and related products when accessed through their web-based management interface. An unauthenticated, remote attacker can exploit this by sending specially crafted HTTP requests. This exploit allows the attacker to gain user-level access to the device's operating system and subsequently elevate their privileges to root.
- Exposure via network interface.
- Attacker sends crafted HTTP requests.
- Attacker gains OS access and elevates privileges.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in Cisco Unified Communications products could allow an attacker to gain control of the underlying operating system. The attacker would need to send specially crafted requests to the product's web interface. Exploiting this could lead to unauthorized access and elevated privileges.
- Attacker skill level: Low
- Required access or conditions: Network access, unauthenticated
- Business risk or urgency: Critical, remote code execution
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
A vulnerability in Cisco Unified Communications products could permit an unauthenticated, remote attacker to execute arbitrary commands on the operating system. This stems from improper validation of user input in HTTP requests, potentially allowing an attacker to gain user-level access and escalate privileges to root. The Cisco Security Impact Rating for this vulnerability is Critical.
- Identify exposed Cisco Unified Communications assets.
- Reduce exposure or isolate affected systems.
