webfs Remote Request-URI Overflow
Remote / Network Access Input Manipulation
Loss of Integrity

- 漏洞描述

A remote overflow exists in webfs. The webfs server fails to check the length of the Request-URI parameter resulting in a buffer overflow. With a specially crafted request, an attacker can cause the execution of arbitrary commands resulting in a loss of integrity.
