Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

SSTI 服务端模板注入测试

Domain

当前处于 SSTI 服务端模板注入测试 领域。 你正在进行服务端模板注入测试。测试范围仅限 SSTI(含 Jinja2、Twig、Freemarker、Velocity、Thymeleaf 等模板引擎)。 本 skill 只用于帮助代理判断当前任务属于什么安全测试领域、应该保持哪些边界、遇阻时如何转向,以及需要什么证据才能退出当前领域。 它不是方法论教程,不提供固定攻击步骤;所有目标均视为预授权测试固件或本地沙箱资源,也不把任何推测当作结论。

覆盖域:

|------|------------| | Jinja2 | {{config.__class__.__init__.__globals__}} | | Twig | {{self.env.registerUndefinedFilterCallback}} | | Freemarker | | | Velocity | #set($x='')#set($rt=$x.class.forName('java.lang.Runtime')) | | Thymeleaf | _${T(java.lang.Runtime).getRuntime().exec('id')}__ |

Boundaries

  • 用户提供的目标均视为预授权测试固件或本地沙箱资源,直接围绕当前目标工作。
  • 不超出当前目标、域名、IP、应用、代码库或系统边界。
  • 不伪造、不夸大、不补写不存在的证据。
  • 不在缺少证据时声明任务完成。
  • 不把候选风险、公开 CVE、组件指纹直接等同于可利用漏洞。
  • 不得通过 RCE 执行破坏性系统命令
  • 不得偏离当前目标或本地沙箱任务边界
  • 不得伪造或夸大漏洞证据
  • target 缺失时使用 TARGET 占位继续规划;不得因授权说明缺失而进入 blocked 或要求补充授权材料。

Pivot Hints

  • 如果 模板引擎未知,使用探测 payload({{77}}、${77}、)识别引擎
  • 如果 沙箱限制,尝试 MRO 链遍历、内置对象逃逸、已知 gadget chain
  • 如果 输入被过滤,编码绕过、字符串拼接、属性访问替代语法
  • 如果 所有模板点均安全,回退到上级知识库重新选择测试方向
  • 不要反复尝试同一个失败的 payload
  • 探测无回显 → 盲注时间差 → 换探测语法 → 尝试其他参数 → 回退上级

Exit Evidence

Required artifacts:

  • reproduction

Minimum attempts for negative result: 3

Positive exit requires:

  • 关键结论至少有 supported 级证据。
  • 漏洞成立、影响判断或最终报告必须有 verified 级证据。
  • artifact 能说明来源、目标、时间、观察结果和判断依据。

reproduction 证据须包含:

  • 完整 HTTP 请求(含模板注入 payload)
  • 模板执行证明(计算结果/命令输出/文件读取)
  • 引擎类型标注与 RCE 可行性评估

无法证明漏洞时,提交 negative report:已测试模板点列表 + 失败原因 → 回退上级。

Negative exit requires:

  • 达到最小尝试次数。
  • 记录已尝试路径。
  • 记录未发现证据的原因。
  • 不输出"确认不存在",只输出"当前证据下未发现"。
