Bad User-Agent trigger HTTP400 Bad Request #3476
Description
Hi,
Debian 8.6
wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
PHP Wrapper : https://github.com/mreiferson/php-wkhtmltox
We issue bad user agent when requesting elements from html. E.g :
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko) \x05?\x7f Safari/534.34
The part \x05?\x7f are supposed to be like wkhtmltopdf/version
In some case, it occurs serious problem and qe have blanck image on pdf because UserAgent trigger a HTTP400 Bad Request. E.g here the random part contain a /n or /r characters so that UA split on 2 header lines :
- UserAgent is User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko)
- . Safari/534.34 (is the bad http header that trigger the HTTP 400)
GET /media/catalog/product/cache/2/image_facing/9df78eab33525d08d6e5fb8d27136e95/BCZ101/i/m/someimage.jpg HTTP/1.1
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko)
. Safari/534.34
Accept: */*
Connection: Keep-Alive
Accept-Encoding: gzip
Accept-Language: en-US,*
Host: **********
Have you any idea to resolve this ?
Thank you,
Pierre
