Ruby is an interpreted scripting language for quick and easy
|
|
object-oriented programming. It comes bundled with a HTTP server
|
|
("WEBrick").

<description>
|
|
<p>
|
|
Giovanni Pellerano, Alessandro Tanasi and Francesco Ongaro reported
|
|
that WEBrick does not filter terminal control characters, for instance
|
|
when handling HTTP logs.
|
|
</p>
|
|

|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could send a specially crafted HTTP request to a
|
|
WEBrick server to inject arbitrary terminal control characters,
|
|
possibly resulting in the execution of arbitrary commands, data loss,
|
|
or other unspecified impact. This could also be used to facilitate
|
|
other attacks.
|
|
</p>

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
