查看流量发现有post upload.php，判断为文件上传漏洞，k为校验参数，c为执行命令，将php代码反向解密，gzuncompress(base64_decode($result))，可看到命令c的执行结果，最后一个为 cat /flag.txt,base64加密后为eJxLy0lMrw6NTzPMS4n3TVWsBQAz4wXi,解压缩为flag{U_f1nd_Me!}

flag{U_f1nd_Me!}

>>> file2 = "eJxLy0lMrw6NTzPMS4n3TVWsBQAz4wXi"; >>> a = base64.b64decode(file2) >>> b = zlib.decompress(a) >>> print(b) flag{U_f1nd_Me!}

反向执行，先解码再解压缩 php -r 'echo gzuncompress(base64_decode(双引号eJxLy0lMrw6NTzPMS4n3TVWsBQAz4wXi双引号;));'

标准签到题,其他的不会,签个到先
查看流量发现有c=cat /flag.txt,回包是eJxLy0lMrw6NTzPMS4n3TVWsBQAz4wXi，需要base64解码+解压缩得到flag. import base64, zlib flag = 'eJxLy0lMrw6NTzPMS4n3TVWsBQAz4wXi' a=zlib.decompress(base64.b64decode(flag)) print(a)
