我正在尝试学习模糊测试未知协议的复杂性，以查找应用程序中的漏洞。我正在使用一个众所周知的易受攻击的应用程序 Disk Savvy Enterprise 10.4.18，其中有一个已知的 SEH 缓冲区溢出。

我目前有一个boofuzz脚本，我正在尝试使用该process_monitor.py脚本，但无法重新启动崩溃的服务。我process_monitor.py在目标机器上运行该脚本，并成功从模糊测试机器连接到该脚本。我的问题是问题标题中的错误——当应用程序崩溃时，它会“尝试”重新启动该进程，但我收到错误

PED-RPC> remote method restart_target cannot be found

我的python脚本的相关部分是：

session = sessions.Session(
    crash_threshold="10000",              # Arbitrary, high crash threshold
    check_data_received_each_request=0,   # Don't check data after every request (slow)
    restart_sleep_time=0.1, 
    sleep_time=0.1,
)
# Define target
target = sessions.Target(
    connection = SocketConnection(dst, dport, proto='tcp')
)
# Define procmon options
target.procmon = pedrpc.Client(dst, 26002)
target.procmon_options = {
    "proc_name" : "disksvs.exe",
    "stop_commands" : ['net stop "Disk Savvy Enterprise"'],
    "start_commands" : ['net start "Disk Savvy Enterprise"']        
}

我process_monitor.py在目标机器上开始执行以下行：

python process_monitor.py --port 26002 --crash_bin diskSaavy_Crashes.txt

以下是启动后和崩溃后的输出结果：

以下是我的模糊测试机器上针对同一次崩溃的 boofuzz 的输出：

我尝试过不同的变体start_commands，既不发送proc_name也不发送stop_commands，并在运行时process_monitor.py指定不同的start_commands，例如在服务名称周围包含完整的路径net.exe和不同的引号转义符等。到目前为止，我尝试过的所有方法均无效。

查看sessions.py和pedrpc.py其他多个文件，我发现__getattr__正用于处理方法调用，但据我所见，restart_target存在于 中sessions.py，所以我不确定为什么 PEDRPC 会说找不到 restart_target……我快要抓狂了。boofuzz 正在做我想要它做的一切，除了重启。

如果这还不够的话，我可以提供更多信息，并且我将非常感激任何能得到的帮助。
