Output:
【漏洞类型】信息泄露漏洞
【严重性】Medium
【漏洞摘要】原始代码在创建服务账户用户时，为每个用户生成了一个电子邮件地址，即`username + "@placeholder.org"`。虽然这些电子邮件地址并没有实际被使用，但这样的行为可能会导致不必要的信息泄露，尤其是如果生成的电子邮件地址被记录或日志记录下来。

【关键代码模式】
- `user.setEmail(username + "@placeholder.org")`
- `serviceAccountUser.setEmail(username + "@placeholder.org")`

【修复方法说明】
修复方法是移除了为服务账户用户设置电子邮件地址的代码，从而避免了不必要的信息泄露。最佳实践是仅在必要时收集用户个人信息，以减少潜在的安全风险。

【漏洞类型】业务逻辑安全漏洞 - 未正确转义的JavaScript特殊字符
【严重性】Medium
【漏洞摘要】原始代码在转义JavaScript特殊字符时，仅对双引号（"）、单引号（'）、反斜杠（\）、斜杠（/）、制表符（\t）、换行符（\n）、回车符（\r）和换页符（\f）进行转义。然而，JavaScript还包含其他特殊字符，如退格符（\b）、垂直制表符（\v）、小于号（<）、大于号（>）以及ECMA-262规范中定义的Unicode行终止符（\u2028和\u2029）。如果未正确转义这些字符，攻击者可以通过在JavaScript代码中插入这些特殊字符来执行跨站脚本攻击（XSS），例如通过注入`<script>`标签或其他JavaScript代码。修复后的代码通过添加对这些字符的转义处理，增强了对XSS攻击的防御能力。
【关键代码模式】JavaScript转义函数、字符串拼接、特殊字符处理。
【修复方法说明】修复方法通过添加对退格符（\b）、垂直制表符（\v）、小于号（<）、大于号（>）以及ECMA-262规范中定义的Unicode行终止符（\u2028和\u2029）的转义处理，增强对XSS攻击的防御能力。遵循最佳实践，确保所有特殊字符在输出到JavaScript环境中时都被适当转义。

【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，允许攻击者通过构造特定的URL来访问服务器上的文件，从而绕过安全限制。具体表现为 `decodePathname` 函数中对用户输入的 `pathname` 进行解码后，直接将其与服务器根目录进行拼接并读取文件内容。如果用户输入的 `pathname` 包含特殊字符（如 `../`），则可能导致读取服务器上任意文件。
【关键代码模式】decodePathname, path.normalize, path.join
【修复方法说明】修复方法通过添加 `ensureUriEncoded` 函数，对所有用户输入的URL进行编码，确保其安全性。

Output:
【漏洞类型】原型污染漏洞
【严重性】高
【漏洞摘要】这是一个原型污染漏洞。代码中的`split`函数通过解析路径字符串来访问对象的属性。如果路径字符串包含特殊的键（如`__proto__`），攻击者可以利用这些键来修改对象的原型。具体表现为，当`key`为`__proto__`时，代码会将其视为一个有效的属性并进行访问或修改，从而污染对象的原型。
【关键代码模式】`split`函数中的`for`循环和`obj[key]`访问模式。
【修复方法说明】修复方法通过在访问对象属性之前检查`key`是否存在于对象的自身属性中（使用`Object.getOwnPropertyNames(obj).indexOf(key) == -1`），从而防止原型污染。这遵循了最佳实践，即在访问或修改对象属性时，应始终验证属性是否为对象的自身属性。

# Exec Binding

This binding integrates the possibility to execute arbitrary shell commands.

## Supported Things

Currently, the binding supports a single type of Thing, being the `command` Thing.

## Binding Configuration

The binding does not require any specific configuration.

**Linux:**
Note that the commands are executed in the context and with the privileges of the process running the Java Virtual Machine.
On a Linux system the system user `openhab` needs to have the privileges needed to execute your intended command.
It is advised to test the correct operation of the command in the scope of the `openhab` user on the command line first:

```shell
sudo -u openhab <YOUR COMMAND>
```

It is not advised to run the virtual machine as superuser/root.

## Thing Configuration

The "command" Thing requires the command to execute on the shell.
Optionally one can specify:

- `transform` - A [transformation](https://www.openhab.org/docs/configuration/transformations.html) to apply on the execution result string.
- `interval` - An interval, in seconds, the command will be repeatedly executed. Default is 60 seconds, set to 0 to avoid automatic repetition.
- `timeout` - A time-out, in seconds, the execution of the command will time out, and lastly,
- `autorun` - A boolean parameter to make the command execute immediately every time the input channel is sent a different openHAB command. If choosing autorun, you may wish to also set `interval=0`. Note that sending the same command a second time will not trigger execution.

For each shell command, a separate Thing has to be defined.

```java
Thing exec:command:uniquename [command="/command/to/execute here", interval=15, timeout=5, autorun=false]
```

The `command` itself can be enhanced using the well known syntax of the [Java formatter class syntax](https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html#syntax).
The following parameters are automatically added:

-   the current date (as java.util.Date, example: `%1$tY-%1$tm-%1$td`)
-   the current (or last) command to the input channel (see below, example: `%2$s`)

note - if you trigger execution using interval or the run channel, the `%2` substitution will use the most recent command (if there has been one) sent to the input channel.  The state of the Item linked to input channel is ignored.

## Channels

All Things support the following channels:

| Channel Type ID | Item Type | Description                                                                          |
|-----------------|-----------|--------------------------------------------------------------------------------------|
| input           | String    | Input parameter to provide to the command                                            |
| output          | String    | Output of the last execution of the command                                          |
| exit            | Number    | The exit value of the last execution of the command                                  |
| run             | Switch    | Send ON to execute the command, the current state tells whether it is running or not |
| lastexecution   | DateTime  | Time/Date the command was last executed, in yyyy-MM-dd'T'HH:mm:ss.SSSZ format        |

## Minimal Example

**demo.things**

```java
Thing exec:command:apc [command="/usr/local/bin/apcaccess status", interval=15, timeout=5]
Thing exec:command:myscript [command="php ./configurations/scripts/script.php %2$s", transform="REGEX((.*?))"]
```

**demo.items**

```java
String APCRaw "[%s]" (All) {channel="exec:command:apc:output"}
Switch APCRunning {channel="exec:command:apc:run"}
Number APCExitValue "[%d]" {channel="exec:command:apc:exit"}
DateTime APCLastExecution {channel="exec:command:apc:lastexecution"}
```

## Full Example

Following is an example how to set up an exec command thing, pass it a parameter, debug it with a rule and set the returned string to an Number Item.

**demo.things**

```java
// "%2$s" will be replace by the input channel command, this makes it possible to use one command line with different arguments.
// e.g: "ls" as <YOUR COMMAND> and "-a" or "-l" as additional argument sent to the input channel in the rule.
Thing exec:command:yourcommand [ command="<YOUR COMMAND> %2$s", interval=0, autorun=false ]
```

**demo.items**

```java
Switch YourTrigger "External trigger [%s]"
Number YourNumber "Your Number [%.1f °C]"

// state of the execution, is running or finished
Switch yourcommand_Run {channel="exec:command:yourcommand:run", autoupdate="false"}
// Arguments to be placed for '%2$s' in command line
String yourcommand_Args {channel="exec:command:yourcommand:input"}
// Output of command line execution
String yourcommand_Out {channel="exec:command:yourcommand:output"}
```

**demo.sitemap**

```java
// Name of file and name of sitemap has to be the same
sitemap demo label="Your Value"
{
        Frame {
            Switch item=YourTrigger
            Text item=YourNumber
        }
}
```

**demo.rules**

```java
rule "Set up your parameters"
when
   Item YourTrigger changed
then
      // here we can take different actions according to source Item
   if(YourTrigger.state == ON){
      yourcommand_Args.sendCommand("Additional Argument to command line for ON")
   }else{
      yourcommand_Args.sendCommand("Different Argument to command line for OFF")
   }
      // Caution : openHAB bus is asynchronous
      // we must let the command work before triggering execution (if autorun false)
end

rule "begin your execution"
when
   Item yourcommand_Args received command
then
      // Separately triggering RUN allows subsequent executions with unchanged parameter %2
      // which autorun does not.
   if (yourcommand_Run.state != ON) {
      yourcommand_Run.sendCommand(ON)
         // the Run indicator state will go ON shortly, and return OFF when script finished
   }else{
      logInfo("Your command exec", "Script already in use, skipping execution.")
   }
end

rule "script complete"
when
   Item yourcommand_Run changed from ON to OFF
then
      // Logging of ending
   logInfo("Your command exec", "Script has completed.")
      // Caution : openHAB bus is asynchronous
      // there is no guarantee the output Item will get updated before the run channel triggers rules
end

rule "process your results"
when
   Item yourcommand_Out received update
then
      // Logging of raw command line result
   logInfo("Your command exec", "Raw result:" + yourcommand_Out.state )
      // If the returned string is just a number it can be parsed
      // If not, a regex or another transformation could be used
   YourNumber.postUpdate(Integer::parseInt(yourcommand_Out.state.toString) as Number)
end

```

# Exec Transformation Service

Transforms an input string with an external program.

Executes an external program and returns the output as a string.
In the given command line the placeholder `%s` is substituted with the input value.

The external program must either be in the executable search path of the server process, or an absolute path has to be used.

## Examples

### General Setup

**Item**

This will replace the visible label in the UI with the transformation you apply with the command <TransformProgram>.

```java
String yourItem "Some info  [EXEC(/absolute/path/to/your/<TransformProgram> %s):%s]"
```

**Rule**

```java
rule "Your Rule Name"
when
    Item YourTriggeringItem changed
then
    var formatted = transform("EXEC","/absolute/path/to/your/<TransformProgram>", YourTriggeringItem.state.toString)
    yourFormattedItem.sendCommand(formatted.toString)
end
```

### Example with a program

Substitute the `/absolute/path/to/your/<TransformProgram>` with

```shell
/bin/date -v1d -v+1m -v-1d -v-%s
```

When the input argument for `%s` is `fri` the execution returns a string with the last weekday of the month, formated as readable text.

```
Fri 31 Mar 2017 13:58:47 IST`
```

Or replace it with

```shell
numfmt --to=iec-i --suffix=B --padding=7 %s
```

When the input argument for `%s` is 1234567 it will return the bytes formated in a better readable form

```shell
1.2MiB
```

### Usage as a Profile

The functionality of this `TransformationService` can be used in a `Profile` on an `ItemChannelLink` too.
To do so, it can be configured in the `.items` file as follows:

```java
String <itemName> { channel="<channelUID>"[profile="transform:EXEC", function="<shellcommand>", sourceFormat="<valueFormat>"]}
```

The shell command to be executed has to be set in the `function` parameter.
The parameter `sourceFormat` is optional and can be used to format the input value **before** the transformation, i.e. `%.3f`.
If omitted the default is `%s`, so the input value will be put into the transformation without any format changes.

Please note: This profile is a one-way transformation, i.e. only values from a device towards the item are changed, the other direction is left untouched.

Output:
【漏洞类型】任意代码执行漏洞
【严重性】High
【漏洞摘要】此代码允许执行任意shell命令，没有对命令进行任何形式的验证或限制。具体表现为`getConfig().get(COMMAND)`获取的命令直接通过`Runtime.exec(cmdArray)`执行。根本原因在于缺乏对用户输入（即shell命令）的验证机制。
【关键代码模式】`Runtime.exec(cmdArray)`、`getConfig().get(COMMAND)`
【修复方法说明】修复方法通过引入命令白名单机制来限制可以执行的命令。具体实现是读取`misc/exec.whitelist`文件中的命令，并在执行命令前进行检查，确保命令在白名单中。

Output:
【漏洞类型】表达式语言注入漏洞
【严重性】High
【漏洞摘要】原始代码中的`addViolation`方法直接使用用户输入的消息字符串作为约束验证的模板，而没有对其进行任何验证或转义。这意味着如果用户输入的消息字符串包含表达式语言（EL）表达式，这些表达式可能会被解析并执行，从而导致表达式语言注入漏洞。特别是，如果EL表达式可以访问和操作敏感数据或执行敏感操作，那么攻击者可能会利用这个漏洞来执行恶意代码。
【关键代码模式】与表达式语言注入相关的关键代码模式包括：
- 使用用户输入作为`ConstraintValidatorContext`的模板构建器的输入。
- 没有对输入进行有效的转义或验证，特别是在使用支持EL表达式的框架时。
【修复方法说明】修复方法通过添加`escapeEl`方法来转义消息字符串中的EL表达式，从而防止它们被解析和执行。最佳实践是在处理来自用户的任何输入时，都要对其进行适当的验证和转义，特别是在这些输入可能会被用于执行代码的上下文中。

Output:
【漏洞类型】XXE（XML外部实体）漏洞
【严重性】High
【漏洞摘要】XXE是一种安全漏洞，允许攻击者通过在XML文档中包含外部实体，执行任意文件读取或远程代码执行等操作。在原始代码中，`XmlRpcParser.java`文件的`reader.setEntityResolver(new DummyEntityResolver());`行没有禁用XML文档中的DOCTYPE声明，这使得攻击者可以利用XXE漏洞读取服务器上的任意文件或发起其他恶意操作。
【关键代码模式】
- `XMLReaderFactory.createXMLReader()`
- `reader.setEntityResolver(new DummyEntityResolver());`
- `reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);`
【修复方法说明】修复方法通过在`XmlRpcParser.java`文件中添加`reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);`行，禁用了XML文档中的DOCTYPE声明，从而防止了XXE攻击的发生。最佳实践是始终禁用外部实体解析，除非明确需要。
