Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists within NetScaler ADC and NetScaler Gateway that could allow unauthorized code execution. This flaw is present in the product's code generation controls. An attacker with low-level authenticated access to the management interface could potentially execute arbitrary code. This could lead to significant business risk if sensitive systems or data are compromised.
- Vulnerable component: NetScaler management interface
- Core weakness: Improper code generation control
- Main business impact: Remote code execution
Attack Path
How an attacker could exploit the issue
An attacker can gain unauthorized control of a NetScaler appliance through a code injection vulnerability. This allows for remote code execution on the appliance's management interface. The attack requires an attacker to have authenticated, low-privileged access to specific network interfaces on the affected appliance. Once access is obtained, the attacker can inject and execute arbitrary code, leading to a compromise of the appliance's management functions and potential access to sensitive data or systems.
- Exposure: Network interface access (NSIP, CLIP, SNIP).
- Attacker starting point: Authenticated, low-privileged user.
- Trigger and result: Code injection leading to remote code execution.
Live Threat
