- Core weakness: Flaw in protocol stack handling
- Main business impact: Remote code execution
Attack Path
How an attacker could exploit the issue
The HTTP Protocol Stack vulnerability allows an unauthenticated attacker to execute remote code. An attacker can send specially crafted HTTP requests to a vulnerable system. Successful exploitation grants the attacker the ability to run arbitrary code with elevated privileges. This can lead to a complete compromise of the affected system and potential lateral movement within the organization's network.
- Exposure via the network.
- Attacker sends malicious HTTP requests.
- Leads to remote code execution.
