# pspy64 工具 - Linux 权限提升

pspy64 工具 Linux 权限提升笔记，包含枚举步骤、利用示例和面向报告的验证。

## 这是什么

当周期性的 root 任务执行可写脚本、不安全的相对路径或存在漏洞的处理程序时，Cron 任务会创建权限提升路径。关键在于证明一个低权限用户能够控制某个特权计划任务将要运行的内容。本页面专注于 **pspy64 工具** 并保持利用流程实用：识别条件，安全验证，然后运行证明影响所需的最小有效载荷。

## 枚举

在运行利用路径之前，先确认本地环境和具体的配置错误。

```bash
cat /etc/crontab
ls -la /etc/cron.*
systemctl list-timers --all
```

## 示例

## pspy64 工具

该工具 [pspy64](https://github.com/DominicBreuker/pspy/releases) 会自动检测 cron 任务。 **Pspy** 是一个命令行工具，用于监控 Unix/Linux 系统上在后台运行的任务，并显示正在启动的新任务。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/zh/privesc/cron-jobs/pspy64-cron-enumeration-linux-privilege-escalation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
