/**
 *

 * Root class for most XWiki actions. It provides a common framework that allows actions to execute just the specific
 * action code, handling the extra activities, such as preparing the context and retrieving the document corresponding
 * to the URL.
 *

 *

 * It defines two methods, {@link #action(XWikiContext)} and {@link #render(XWikiContext)}, that should be overridden by
 * specific actions. {@link #action(XWikiContext)} should contain the processing part of the action.
 * {@link #render(XWikiContext)} should return the name of a template that should be rendered, or manually write to the
 * {@link XWikiResponse response} stream.
 *

 *

 * Serving a request goes through the following phases:
 *

 *

 *
Wrapping the request and response object in XWiki specific wrappers

 *
Prepare the request {@link XWikiContext XWiki-specific context}

 *
Initialize/retrieve the XWiki object corresponding to the requested wiki

 *
Handle file uploads

 *
Prepare the velocity context

 *
Prepare the document objects corresponding to the requested URL

 *
Send action pre-notifications to listeners

 *
Run the overridden {@link #action(XWikiContext)}

 *
If {@link #action(XWikiContext)} returns true, run the overridden {@link #render(XWikiContext)}

 *
If {@link #render(XWikiContext)} returned a string (template name), render the template with that name

 *
Send action post-notifications to listeners

 *

 *

 * During this process, also handle specific errors, like when a document does not exist, or the user does not have the
 * right to perform the current action.
 *

Output:
【漏洞类型】跨站脚本（XSS）漏洞
【严重性】中等
【漏洞摘要】此代码在`localizePlainOrKey`函数中存在安全漏洞，未对本地化字符串进行适当的HTML转义。具体表现为，本地化字符串中的特殊字符（如`<`, `>`, `&`, `"`等）可能被解析为HTML或JavaScript代码，导致XSS攻击。问题行是：
```java
return StringUtils.defaultString(getLocalization().getTranslationPlain(key, parameters), key);
```
根本原因是，函数返回的未转义的字符串可能被嵌入到HTML页面中，从而被浏览器解析为代码。
【关键代码模式】`StringUtils.defaultString()`, `getLocalization().getTranslationPlain()`, `return`语句
【修复方法说明】通过XML转义本地化字符串，防止XSS攻击：
```java
return XMLUtils.escape(StringUtils.defaultString(getLocalization().getTranslationPlain(key, parameters), key));
```
适用的最佳实践是，对所有用户提供的输入和从外部系统获取的输出进行适当的转义，以防止注入攻击。

【漏洞类型】路径遍历漏洞
【严重性】High
【漏洞摘要】原始代码中，用户输入的`$request.xredirect`参数未经充分验证，直接用于设置`$cancelURL`和`$redirectparam`。如果攻击者能够控制`$request.xredirect`，他们可以注入恶意的URL，导致路径遍历攻击。例如，攻击者可能会将`$request.xredirect`设置为`../path/to/malicious/resource`，从而访问或修改不应该被访问的文件。
【关键代码模式】
- 未验证的用户输入：`$request.xredirect`
- 直接使用用户输入构建URL：`#set ($cancelURL = $request.xredirect)`
- 未正确处理URL参数：`#set ($redirectparam = "&xredirect=$escapetool.url($request.xredirect)")`
【修复方法说明】修复方法通过调用`$getSanitizedURLAttributeValue('a','href',$request.xredirect,$doc.getURL(),$cancelURL)`来对`$request.xredirect`进行服务器端验证和清理，确保生成的`$cancelURL`和`$redirectparam`是安全的。

Output:
【漏洞类型】跨站脚本攻击（XSS）
【严重性】High
【漏洞摘要】此代码存在跨站脚本攻击（XSS）漏洞，尤其是在处理用户输入的`request.xredirect`参数时。虽然`escapetool.xml`用于输出HTML，但未对`request.xredirect`参数进行充分的验证和清理，可能导致攻击者注入恶意脚本。具体表现为在`displayConfirmMessage`宏中，`request.xredirect`参数直接被输出到HTML中，而没有对其进行进一步的清理。
【关键代码模式】未验证的用户输入
【修复方法说明】修复方法通过调用`getSanitizedURLAttributeValue`宏对`request.xredirect`参数进行了清理，确保其输出到HTML中时是安全的。这解决了未验证用户输入的问题。

Output:
【漏洞类型】URL重定向安全漏洞
【严重性】Medium
【漏洞摘要】这是一个URL重定向安全漏洞。原始代码中，`$editorUrl`的值是从用户请求头中的`Referer`字段获取的，如果攻击者能够控制`Referer`字段的值，他们可以引导用户重定向到恶意网站。漏洞的根本原因在于直接使用了用户提供的`Referer`字段作为表单的`action`属性值，而没有进行适当的验证和消毒。
【关键代码模式】
- `$editorUrl = "$!request.getHeader('Referer')"`
- `action="$!{escapetool.xml($editorUrl)}"`
【修复方法说明】修复方法通过引入`$fallbackUrl`作为默认的编辑URL，并使用`#getSanitizedURLAttributeValue`函数来验证和消毒`$editorUrl`，确保在用户输入不可信的情况下，表单的`action`属性值仍然安全。

Output:
【漏洞类型】未验证的用户输入
【严重性】High
【漏洞摘要】原始代码在处理用户输入的 `request.xredirect` 参数时，没有进行适当的验证和清理。具体表现为在 `displayConfirmMessage` 宏中，`request.xredirect` 参数直接被用作 `cancelUrl` 的值，而没有经过任何安全处理。如果用户输入恶意的 URL，攻击者可以利用此漏洞进行重定向攻击，可能导致用户被引导到恶意网站或执行其他恶意操作。
【关键代码模式】与用户输入相关的代码行，例如：
```velocity
#if("$!{request.xredirect}" != '')
    #set($cancelUrl = "$request.xredirect")
#else
    #set($cancelUrl = $doc.getURL())
#end
```
关键关键词：`request.xredirect`, `getURL()`
【修复方法说明】修复方法通过调用 `#getSanitizedURLAttributeValue('a','href',$request.xredirect,$doc.getURL(),$cancelUrl)` 来对 `request.xredirect` 参数进行安全处理，以防止潜在的恶意重定向。这种方法确保了 URL 参数的合法性，从而保护用户免受重定向攻击。

【漏洞类型】路径遍历漏洞
【严重性】High
【漏洞摘要】此代码存在路径遍历漏洞，具体表现为在`displayCompletelyDeleteConfirmMessage`宏中，未对用户输入的`xredirect`参数进行充分验证和转义。攻击者可以通过 manipulate `xredirect` 参数来重定向到任意页面，从而可能访问或操作不应该被访问的资源。
【关键代码模式】用户输入的参数未验证和转义，特别是在生成URL时。
【修复方法说明】引入`#getSanitizedURLAttributeValue`宏来验证和转义`xredirect`参数，以防止路径遍历攻击。
