Output:
【漏洞类型】XML eXternal Entity injection (XXE)
【严重性】High
【漏洞摘要】这是一个XML外部实体注入漏洞。在`getDocumentBuilder`方法中，使用了`DocumentBuilderFactory.newInstance().newDocumentBuilder()`来创建XML文档构建器，但没有设置相关的安全特性以防止XXE攻击。攻击者可以通过构造恶意XML输入来执行外部实体注入，从而可能获取敏感信息或执行其他恶意操作。
【关键代码模式】`DocumentBuilderFactory.newInstance().newDocumentBuilder()`，未设置安全特性。
【修复方法说明】修复方法通过设置`DocumentBuilderFactory`的特性来防止XXE攻击，包括禁用外部文档类型声明和外部实体解析。这确保了XML解析过程不会加载外部的DTD或实体，从而防止了XXE攻击。

## This template is called by the create action which binds some context variables as it executes, based on
## the request and the current document. These variables can be used in this template:
## * $spaceReference - the space reference of the new document, read from the "spaceReference" parameter
## * $name - the name to use for the new document, read from the "name" parameter
## * $isSpace - true if we are creating a non-terminal document ($name is the space name), false if we are
##              creating a terminal document ($name is the document name). Determined by the create action
## * $availableTemplateProviders - list of template provider documents available from the current space
##
## Note: Make sure to use these bindings instead of directly using the request parameters, as the bindings
## also consider backwards compatibility and convert older "space" and "page" parameters if they are passed.
## ---------------------------------------------------------------------------------------------------------

## ---------------------------------------------------------------------------------------------------------
## This template can be passed a parent document reference in parameter (using the "parent" parameter).
## If a parent parameter is passed, use it to set the parent when creating the new page.
## If no parent parameter was passed, the create action will determine it to be the current document if it
## exists or the Main space's webhome if the current document does not exist.
## ---------------------------------------------------------------------------------------------------------
#set ($parent = "$!request.getParameter('parent')")

## ---------------------------------------------------------------------------------------------------------
## This parent can be passed a title for the document to create (using the "title" parameter).
## The title is used to automatically compute a page name, which can then be customized by the user.
## If no title is given, the page name (if set) will be used as title.
## ---------------------------------------------------------------------------------------------------------

## ---------------------------------------------------------------------------------------------------------
## If there was an exception creating the page because of invalid space, notify.
## Should set the other variables only if there is no exception. Otherwise, if there's an exception other than the
## 11016 one, nothing will be displayed, depending on the other passed parameters.

Output:
【漏洞类型】XSS（跨站脚本攻击）
【严重性】High
【漏洞摘要】
此代码存在跨站脚本攻击（XSS）漏洞。具体表现为在多个地方，如错误消息和表单字段，直接将用户输入插入到HTML中，而没有进行适当的HTML转义。例如，在问题行79中，`$services.localization.render('core.create.page.error.docalreadyexists', ["${existingDocumentReference}", $xwiki.getURL($existingDocumentReference, 'view', ''), $xwiki.getURL($existingDocumentReference, 'edit', '')])`，`$existingDocumentReference` 是从请求参数中获取的，并且没有进行HTML转义，这可能导致恶意用户输入的脚本被执行。

【关键代码模式】
- 未验证的用户输入：`$!request.getParameter('parent')`、`$!request.title`、`$!request.templateprovider`、`$!request.template`、`$!exception`、`$!{escapetool.velocity($name)}`。
- 直接插入HTML：如 `$services.localization.render('core.create.page.error.docalreadyexists', ["${existingDocumentReference}", $xwiki.getURL($existingDocumentReference, 'view', ''), $xwiki.getURL($existingDocumentReference, 'edit', '')])`。
- HTML转义缺失：如 `${existingDocumentReference}` 没有使用 `$escapetool.xml` 进行转义。

【修复方法说明】
通过在用户输入插入HTML之前使用 `$escapetool.xml` 进行HTML转义，来防止XSS攻击。例如，在问题行79中，将 `["${existingDocumentReference}", $xwiki.getURL($existingDocumentReference, 'view', ''), $xwiki.getURL($existingDocumentReference, 'edit', '')]` 改为 `[$escapetool.xml("${existingDocumentReference}"), $xwiki.getURL($existingDocumentReference, 'view', ''), $xwiki.getURL($existingDocumentReference, 'edit', '')]`。

【最佳实践或安全编码技术】
- 对所有用户输入进行严格的HTML转义。
- 使用安全的API来处理用户输入，避免直接拼接字符串。

## This template is called by the create action which binds some context variables as it executes, based on
## the request and the current document. These variables can be used in this template:
## * $spaceReference - the space reference of the new document, read from the "spaceReference" parameter
## * $name - the name to use for the new document, read from the "name" parameter
## * $isSpace - true if we are creating a non-terminal document ($name is the space name), false if we are
##              creating a terminal document ($name is the document name). Determined by the create action
## * $availableTemplateProviders - list of template provider documents available from the current space
##
## Note: Make sure to use these bindings instead of directly using the request parameters, as the bindings
## also consider backwards compatibility and convert older "space" and "page" parameters if they are passed.
## ---------------------------------------------------------------------------------------------------------

## ---------------------------------------------------------------------------------------------------------
## This template can be passed a parent document reference in parameter (using the "parent" parameter).
## If a parent parameter is passed, use it to set the parent when creating the new page.

## exists or the Main space's webhome if the current document does not exist.

Output:
【漏洞类型】注入漏洞
【严重性】High
【漏洞摘要】原始代码中存在注入漏洞的问题。具体表现为，未对用户输入的`$templateProvider`、`$allowedSpaces.get(0)`和`$allowedSpaces.toString()`进行适当的HTML转义处理。这可能导致恶意用户通过构造特定的输入来注入恶意HTML或脚本，从而进行跨站脚本攻击（XSS）。
【关键代码模式】
- `$services.localization.render('core.create.template.allowedspace.inline', [$templateProvider, $allowedSpaces.get(0)])`
- `$services.localization.render('core.create.template.allowedspaces.inline', [$templateProvider, $allowedSpaces.toString()])`
- `$escapetool.xml("${existingDocumentReference}")`
【修复方法说明】修复方法通过调用`$escapetool.xml()`函数对关键用户输入进行HTML转义，从而防止XSS攻击。这遵循了最佳实践，即对所有用户输入进行适当的编码处理，以防止潜在的安全漏洞。

## This template is called by the create action which binds some context variables as it executes, based on
## the request and the current document. These variables can be used in this template:
## * $spaceReference - the space reference of the new document, read from the "spaceReference" parameter
## * $name - the name to use for the new document, read from the "name" parameter
## * $isSpace - true if we are creating a non-terminal document ($name is the space name), false if we are
##              creating a terminal document ($name is the document name). Determined by the create action
## * $availableTemplateProviders - list of template provider documents available from the current space
##
## Note: Make sure to use these bindings instead of directly using the request parameters, as the bindings
## also consider backwards compatibility and convert older "space" and "page" parameters if they are passed.
## ---------------------------------------------------------------------------------------------------------

## ---------------------------------------------------------------------------------------------------------
## This template can be passed a parent document reference in parameter (using the "parent" parameter).
## If a parent parameter is passed, use it to set the parent when creating the new page.
## If no parent parameter was passed, the create action will determine it to be the current document if it
## exists or the Main space's webhome if the current document does not exist.

## ---------------------------------------------------------------------------------------------------------

Output:
【漏洞类型】跨站脚本（XSS）
【严重性】High
【漏洞摘要】原始代码在处理用户输入时存在不足之处，具体表现为未对模板提供者错误信息进行适当的转义。当用户输入恶意脚本时，这些脚本将被渲染到页面上，从而引发跨站脚本攻击。问题行位于`#if("$!exception" != '' && $exception.code == 11016) ... #end`和`#if("$!exception" != '' && $exception.code == 11002) ... #end`之间，以及`#if("$!exception" != '' && $exception.code == 11017) ... #end`中。
【关键代码模式】关键代码模式是未对用户输入或动态生成的内容进行适当的转义。特别是在`$services.localization.render`函数返回的内容中，未使用`$escapetool.xml`进行转义。
【修复方法说明】修复方法通过在模板提供者错误信息的渲染中添加`$escapetool.xml`转义，防止恶意脚本被渲染到页面上，从而解决问题。此修复遵循了最佳安全实践，即对所有用户输入和动态生成的内容进行转义处理，以防止XSS攻击。
