批量运营CodeQL Cli扫描结果(简易版)

背景&目标

CodeQL Cli适合批量做扫描，但是扫描结果并不适合直接做批量的运营，仅适合一些实锤的问题，对于一些还需要人工处理判断的结果就不太适合了(要看源码、调用上下文)；如果使用VSCode插件来做，也只是单条规则扫单个/多个数据库，结果倒是很友好，点点点就能读代码来分析了，所以这种用法不适合批量的query扫描。

如果付费的话自然是可以解决了，可以在CI/CD中集成，就方便多了 -。- 但是对于个人使用者来说不太现实，所以我就想用一个简单的办法来实现这个目的

CodeQL cli批量扫描结束后，导入数据库+历史query结果，直接在vscode里运营结果，流程为：

CI/CD 扫描 ---> 结果(数据库+扫描结果) ---> 导入VSCode运营

批量导入数据库，而不是通过GUI点点点导入
导入扫描结果，历史query不要清理，为的是把cli的扫描结果导入对应目录之后可以直接在CodeQL的query history中看到

批量导入数据库

查看日志，猜测是类似的做法，解析某个配置文件，然后导入，所以要么修改文件，要么直接把数据库目录copy过去就行

/**

 * databases have been recently selected.
 *
 * The source of truth of the current state resides inside the
 * `DatabaseManager` class below.
 */

/**
 * The name of the key in the workspaceState dictionary in which we
 * persist the current database across sessions.
 */
const CURRENT_DB = "currentDatabase";

/**
 * The name of the key in the workspaceState dictionary in which we
 * persist the list of databases across sessions.
 */
const DB_LIST = "databaseList";

导出信息就能看到了，所以直接改数据库就能添加多个数据库了

/home/muhe/.config/Code/User/workspaceStorage/693bdf324f8bd69cec87e06d65e8d000/state.vscdb

{
    "databaseList": [
        {
            "uri": "file:///home/muhe/Work/codeql_multi_work/XNU-revision-2018-October-28--14-31-48",
            "options": {
                "ignoreSourceArchive": false,
                "dateAdded": 1684233047172,
                "language": "cpp"
            }
        }
    ],
    "currentDatabase": "file:///home/muhe/Work/codeql_multi_work/XNU-revision-2018-October-28--14-31-48"
}

尝试直接修改这个数据库就可以批量导入了，不需要挨个点点点了 :)

导入扫描结果

`query-history`

扫描结果的导入是有个json文件描述的

Reading query history

我这里随意跑了两个Query，查看这个文件可以看到这两次记录:

        "message": "finished in 0 seconds",
        "resultCount": 1461,
        "sortedResultsInfo": {}
      }
    }
  ]
}

所以把query结果按照这个格式填进去就行了。

配置文件中需要的CodeQL cli信息获取

❯ tree -L 1 .
.
├── evaluator-log-end.summary
├── evaluator-log.jsonl
├── evaluator-log.summary
├── evaluator-log.summary.map
├── interpretedResults.sarif
├── query.log
├── results.bqrs
├── results.dil
└── timestamp

经过测试，运营只需要扫描结果就行，其他的可以忽略

Evaluator Log 相关可以不要
DIL 也可以不要，可以用于query调优啥的，我们只运营结果就不考虑了

FYI: 其他的文件(log、dil等)是为了下面菜单中展示的功能做的：

批量query & 导入结果分析

一般来说，我们会使用到开源的规则以及自己写的规则，如果有一定的积累的话，自己的规则可以搞成一个qlpack，方便后面对新目标的快速分析或者批量查找问题。

通用规则/开源规则

第一种情况，可以利用下面的命令，批量跑特定的规则集

# muhe @ muhe-NUC11PAHi5 in ~/Tools/vscode-codeql-starter/ql/cpp/ql/src/codeql-suites on git:codeql-cli/latest o [18:53:36]
$ tree -L 1 .
.
|-- cpp-code-scanning.qls
|-- cpp-lgtm-full.qls
|-- cpp-lgtm.qls
|-- cpp-security-and-quality.qls
|-- cpp-security-experimental.qls
|-- cpp-security-extended.qls
`-- exclude-slow-queries.yml

0 directories, 7 files

比如我们尝试使用cpp-security-and-quality.qls这个规则集跑老版本的XNU作为演示

codeql database run-queries --ram=16384 --threads=12 XNU-revision-2018-October-28--14-31-48  --min-disk-free=1024 -v ~/Tools/vscode-codeql-starter/ql/cpp/ql/src/codeql-suites/cpp-security-and-quality.qls

FYI: 可以使用 codeql resolve queries ~/Tools/vscode-codeql-starter/ql/cpp/ql/src/codeql-suites/cpp-security-and-quality.qls --format=text 获取这个规则集包含了哪些query

第二种就使用规则仓库中PICO的pack就行，或者直接指定一个qls扫，就是类似的做法了，比如可以自己搞一个qlpack：

codeql database run-queries --ram=16384 --threads=8  --min-disk-free=1024  -- [database] [qlpack]

对于这种跑query的方式，如果不指定输出，默认结果会放在数据库的 results目录下，比如:

所以可以写个脚本

修改state.vscdb，批量把codeql db导入
修改query-history文件，把扫描结果导入

最终实现的效果如下 :)

FYI: 两个关键文件的路径不同平台下大同小异:

if 'macOS' in current_platform:
    globalStorage = f'{os.getenv("HOME")}/Library/Application Support/Code/User/globalStorage'
    workspaceStorage = f'{os.getenv("HOME")}/Library/Application Support/Code/User/workspaceStorage'
elif 'Linux' in current_platform:
    globalStorage = f'{os.getenv("HOME")}/.config/Code/User/globalStorage'
    workspaceStorage = f'{os.getenv("HOME")}/.config/Code/User/workspaceStorage'
elif 'Windows' in current_platform:
    globalStorage = f'{os.getenv("APPDATA")}\\Code\\User\\globalStorage'
    workspaceStorage = f'{os.getenv("APPDATA")}\\Code\\User\\workspaceStorage'
else:
    # error
