Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects Control Web Panel, a web-based server management tool. It allows an unauthenticated attacker to execute arbitrary commands on the server by submitting specially crafted input. This could potentially lead to a complete compromise of the affected system.
- Unauthenticated attackers can run commands.
- Impacts systems allowing remote server management.
- Confirm relevance and exposure of this tool.
Attack Path
How an attacker could exploit the issue
Attackers can exploit an OS command injection vulnerability in the protected directory module of Control Web Panel to execute arbitrary commands. This occurs when unescaped input is submitted through the file POST parameter in the `acc=deletedp` action, allowing commands to be directly passed into a shell execution function. Successful exploitation could lead to code execution within the user panel's context.
- No authentication or user interaction needed.
- Submit unescaped input to the file POST parameter.
- Achieve arbitrary command execution.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, unescaped input in the protected directory module could allow attackers to execute arbitrary commands by submitting input through the file POST parameter in the acc=deletedp action, leading to code execution within the user panel context.
- Arbitrary commands could be executed.
- Unescaped input via file POST parameter.
- Code execution within user panel context.
Operational Fix
Recommended remediation, mitigation, and detection steps
Technical leaders and system owners must prioritize identifying all instances of Control Web Panel, confirming their accessibility, and assessing their business criticality to determine the appropriate remediation approach. This involves engaging with application owners, infrastructure teams, and potentially vendor management to coordinate a risk-based response, which may include planned patching, configuration changes, or other mitigating actions.
- Identify and confirm affected CWP instances.
- Verify external exposure and business criticality.
- Plan remediation with accountable owners.
