CVE-1999-1281

Step 1: Target Identification: An attacker identifies a server running a vulnerable version of Breeze Network Server, likely through port scanning or reconnaissance.

Step 2: Request Crafting: The attacker crafts a malicious HTTP request targeting the configbreeze CGI program. This request may contain specific parameters or data designed to exploit the vulnerability.

Step 3: Request Delivery: The attacker sends the crafted HTTP request to the vulnerable server.

Step 4: CGI Program Execution: The configbreeze CGI program receives and processes the malicious request.

Step 5: Vulnerability Trigger: The program's flawed logic or lack of input validation causes an error, leading to a system reboot.

Step 6: System Reboot: The server initiates a reboot sequence, resulting in a denial-of-service condition.

The vulnerability stems from a flaw in the configbreeze CGI program within the development version of Breeze Network Server. The program likely lacks proper input validation or error handling when processing requests. Specifically, a crafted request, possibly containing malformed data or a specific sequence of commands, causes the server to enter an unexpected state, leading to a system reboot. The root cause is likely a logic error or a resource exhaustion issue triggered by the CGI program's interaction with the operating system's core functions. The exact nature of the flaw is not specified in the CVE, making it difficult to pinpoint the exact function or logic that is failing. However, the outcome is a complete system shutdown, indicating a critical vulnerability.
