java - HTTP 响应中 HP Fortify 的 header 操作问题 [java]

Question

我正在尝试修复 HP Fortify Scan 针对此代码返回的“Header Manipulation”问题。我不知道文件在上传过程中是否已经过验证(我认为没有)。我尝试使用 RegEx 来验证文件名但没有成功。 任何人都可以帮助我吗？

b = uploadedFiles.getFilecontent().getBytes(1,
                        uploadedFiles.getFilesize().intValue());
                if (b != null) {
                    response.reset();
                    String fileName = uploadedFiles.getFilename();
                    String header = "attachment; filename=\"" + fileName + "\"";
                    String contentType = uploadedFiles.getFilecontenttype();
                    response.setContentType(uploadedFiles.getFilecontenttype());
                    response.addHeader("Content-Transfer-Encoding", "Binary");
                    response.addHeader("Cache-Control", "must-revalidate, private");
                    response.setContentLength(b.length);
                    FileCopyUtils.copy(b, response.getOutputStream());
                    response.getOutputStream().flush();
                    response.getOutputStream().close();
                }

我尝试过的:

String fileName = uploadedFiles.getFilename();
String regex = "[a-zA-Z._ ]*";
if (b != null && fileName.matches(regex)) {
                response.reset();
                // String fileName = uploadedFiles.getFilename();
                String header = "attachment; filename=\"" + fileName + "\"";
                String contentType = uploadedFiles.getFilecontenttype();
                response.setContentType(uploadedFiles.getFilecontenttype());
                response.addHeader("Content-Transfer-Encoding", "Binary");
                response.addHeader("Cache-Control", "must-revalidate, private");            
                response.setHeader("Content-Disposition", header);
                response.setContentLength(b.length);
                FileCopyUtils.copy(b, response.getOutputStream());
                response.getOutputStream().flush();
                response.getOutputStream().close();
            }

通过使用 RestTemplate 和使用 HttpHeader 作为授权 header ，下面的代码能够解决 header 操作问题。

import org.apache.commons.lang3.StringUtils;

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headersNew = new HttpHeaders();
//Below 2 Line solve the problem
String sanitizedToken = StringUtils.normalizeSpace(yourJwtToken);
headersNew.setBearerAuth(sanitizedToken); //This line where fortify reporting issue earlier
String url ="Your url";
HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(null, headersNew);
ResponseEntity<Object> response =
                    restTemplate.exchange(url,
                            HttpMethod.GET,
                            entity,
                            Object.class);
