Descriptions
redirect() in bottle.py in bottle 0.12.10 doesn't filter a "\r
" sequence, which leads to a CRLF attack, as demonstrated by a redirect("233\r
Set-Cookie: name=salt") call.
redirect() en bottle.py en bottle 0.12.10 no filtra una secuencia "\r
", lo que lleva a un ataque CRLF, según lo demostrado por una llamada redireccionada ("233\r
Set-Cookie: name=salt").
It was discovered that bottle, a WSGI-framework for the Python programming language, did not properly filter "\r
" sequences when handling redirections. This allowed an attacker to perform CRLF attacks such as HTTP header injection.
