-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi , I'm testing somethings in Apache about the url parsing of the server , i don't now if the Apache server parse completely provided urls when those urls are in this format: [PROTOCOL HTTP / HTTPS ][SITE]/[DIR TO OVERRIDE RULES]/../[DIR TO OVERRIDE RULES]/../[DIR TO OVERRIDE RULES]/../[DIR TO OVERRIDE RULES]/../[DIR TO OVERRIDE RULES]/../../[DIR TO OVERRIDE RULES]/../../../[DIR WITH NO RULES OR ACCESS CONTROL]/../[THE SAME NO CONTROLLED DIR OR OTHER NOT CONTROLLED]/../../../../[DIR WITH NO CONTROL RULES]/../ If this can be possible , it can't affect ip based access controls but other controls can be affected , or not ? This is not a vulnerability because i can't confirm it but i want to check the source code , i'm open for suggestions . i'm posting this because i'm a little confused , and other possibilities , if the url is encoded ? does Apache check correctly this when it is encoded ? One thing is sure: this can not affect ip based rules such as deny or allow PS: can be this related with the mod_write vulnerabilities ?
