Horizon Alert
Summary of the vulnerability and why it matters
An issue discovered in Aviatrix Controller allows an unauthenticated attacker to execute arbitrary code. This vulnerability stems from the improper handling of special characters within operating system commands. The potential impact includes unauthorized code execution, which can lead to significant business risk and compromise of sensitive data.
- Vulnerable component: Aviatrix Controller
- Core weakness: Improper OS command handling
- Main business impact: Arbitrary code execution
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can execute arbitrary code on an organization's systems. This is possible by sending specially crafted input to specific API endpoints. The vulnerability exists in Aviatrix Controller software.
- Exposed API endpoints receive attacker input.
- Attacker sends shell metacharacters.
- Arbitrary code execution results.
Live Threat
Current exploitation, exposure, and threat context
An unauthenticated attacker can exploit a command injection vulnerability within Aviatrix Controller. Exploitation involves sending specially crafted commands through API endpoints that do not properly neutralize user input. This could allow unauthorized code execution, potentially leading to a complete compromise of the affected systems. The vulnerability has been actively exploited in the wild, with observed instances including cryptocurrency mining and backdoor deployment, posing a significant business risk. Given the severity and active exploitation, this should be treated as an urgent matter.
- Low attacker skill level required.
- Unauthenticated remote access is sufficient.
- High business risk and urgency.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
An unauthenticated attacker can execute arbitrary code on Aviatrix Controllers due to improper handling of special elements in OS commands. This vulnerability allows for the injection of shell metacharacters, posing a significant risk to affected systems. The organization should prioritize addressing this critical issue to maintain system integrity and security.
- Identify all Aviatrix Controller instances.
- Isolate exposed Controller instances.
- Apply vendor fixes, verify, and monitor.
