该漏洞扫描器可用于扫描 Juniper 防火墙,以判断其是否易受 CVE-2023-36845 影响。由于该扫描器基于 go-exploit 构建,因此包含两个阶段:
LD_PRELOAD 消息,使易受攻击的系统生成一条(无害的)错误消息。有关利用 CVE-2023-36845 的更多详细信息,请参阅我们的博客:Juniper 防火墙上的无文件远程代码执行。
你可以使用 makefile 构建一个 docker 容器:
make docker
或者,如果你已有可用的 Go 构建环境,直接使用 make 即可:
albinolobster@mournland:~/cve-2023-36845-scanner$ make
gofmt -d -w scan.go
golangci-lint run --fix scan.go
GOOS=linux GOARCH=arm64 go build -o build/scan_linux-arm64 scan.go
该工具基于 go-exploit 构建,因此有多种方式提供待扫描的目标。完整说明可在项目的 扫描文档 中找到,下面给出一些示例:
$ ./build/scan_linux-arm64 -a -v -e -rhost 10.12.72.1 -log-json=true | jq 'select(.msg == "Vulnerable")'
{

"level": "SUCCESS",
"msg": "Vulnerable",
"vulnerable": true,
"rhost": "10.12.72.1",
"rport": 80
}

go-exploit 支持通过提供的目标 csv 进行扫描,csv 的格式为:host, port, anything if ssl is enabled(不过在使用 -a 时 SSL 字段会被忽略)。完整详情请参阅扫描文档。它还支持通过代理进行扫描。命令示例如下:
$ ./build/scan_linux-arm64 -v -e -rhosts-file ~/junos/junos.targets.csv -proxy socks5://127.0.0.1:9050 -log-file vulnscan.json
^C
$ tail vulnscan.json
