我在 Ubuntu 机器上使用 boofuzz 0.1.6。我正在尝试让 process_monitor_unix 连接到我想要进行模糊测试的服务器程序。当我启动 procmon 和我的脚本时,我在 procmon 上得到以下输出:

[05:47.20] Process Monitor PED-RPC server initialized:
[05:47.20]   listening on:  0.0.0.0:26002

APCI parameters:

 t1: 15
 t2: 10
 t3: 20
 k: 12
 w: 8

输出“APCI 参数 ...”是每次服务器启动时发送的服务器消息。因此,我认为它已经启动并正在运行。我的问题是它没有响应传入的 tcp 包。我的 fuzzscript 的输出如下:

[2020-03-19 17:47:24,314]     Info: Web interface can be found at http://localhost:26000
[2020-03-19 17:47:24,316] Test Case: 1: activate->s_formatAPDU.no-name.1 
[2020-03-19 17:47:24,316]     Info: Type: Bytes. Default value: b'\x91\xef\xa5'. Case 1 of 270 overall.
[2020-03-19 17:47:24,316]   Test Step: Calling procmon pre_send()

它卡在这个测试步骤中。当我先启动服务器,然后是 procmon,然后是 fuzzscript 时,我收到以下错误:

[10:29.51] Process Monitor PED-RPC server initialized:

现在这对我来说似乎很奇怪,因为 pid 21574 不是正在运行的服务器进程的 pid。现在有人对此有更多了解吗?即使是疯狂的猜测也值得赞赏!如果您还需要其他信息,我很乐意提供。

我通过删除 "proc_name": '/home/rico/iec60870/lib60870-master/lib60870-C/examples/cs104_server/simple_server'我的 fuzzscript 中的行来修复错误。我还必须确保服务器不是!不是!当我启动我的 fuzzscript 时已经在运行。现在,服务器在运行 procmon 的终端中启动。

我不知道是否有更好的方法来解决这个问题,但至少 procmon 现在可以完成它的工作。
