Counter.exe是Behold!Software出的一个Web计数器产品。Counter.exe存在一个问题，可被远程入侵者用来拒绝服务。恶意用户可以提交一个类似”http://www.example.com/scripts/counter.exe?%0A”的畸形请求进行攻击。类似的，提交http://www.example.com/scripts/counter.exe?AAAAAA……后面跟上超过2200个A的请求也会导致拒绝服务。所有的请求都会存在队列中，直到错误被清除。系统内存会被一直消耗。

A set of vulnerabilities in the counter.exe web hit counter program enables denial of service attacks.

A malicious user can create a malformed like ",1" entry in the counter.log file by requesting a URL of the form "http://www.example.com/scripts/counter.exe?%0A". Any further attempt for request will result in an Access Violation in counter.exe.

A similar vulnerability exists if a user requests a URL of the form "http://www.example.com/scripts/counter.exe?AAAAA" with over 2200 A's.

All further requests for counter.exe are queued and are not processed until the error messages are cleared at the console. System memory may be decremented each time a request for counter.exe is queued.
