Descriptions

The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 via UTF-7 encoding.

La función list_directory en lib/SimpleHTTPServer.py en SimpleHTTPServer en Python anterior a v2.5.6c1, v2.6.x anterior a v2.6.7 RC2, y v2.7.x anterior a v2.7.2 no pone un parámetro charset en la cabecera Content-Type de HTTP, lo que hace más fácil para los atacantes remotos realizar ataques XSS contra Internet Explorer 7 a través de codificación UTF-7.
