redteam-xxe-detail-pack

redteam-xxe-detail-pack is a skill for Claude Code, Codex from Unclecheng-li/DeepSec. It costs 57 tokens per session (810 once invoked), scanned A, a copy of redteam-xxe-detail-pack, MIT.

A guide for authorized testing of XXE, a weakness in XML parsers that may let supplied XML refer to external files or services. It covers file reading, server-side request forgery, blind testing, and related XML variants.

In plain words
What is it for?
Use it to assess external entities, parameter entities, XInclude, SVG or DOCX uploads, and blind out-of-band behavior. It helps record requests, responses, attempted paths, and verified conclusions.
Why use it?
It keeps XML security testing within the target’s boundaries and requires reproducible evidence before declaring a vulnerability. It also provides directions when one XML technique is blocked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

redteam-xxe-detail-pack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to redteam-xxe-detail-pack — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

XXE XML 外部实体注入测试

Domain

当前处于 XXE XML 外部实体注入测试 领域。 你正在进行 XXE 漏洞测试。测试范围仅限 XML 外部实体注入(含文件读取、SSRF、盲 XXE、参数实体等)。 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:

变体 典型场景
经典 XXE 外部实体文件读取
盲 XXE OOB 外带数据
参数实体 DTD 内嵌套利用
XInclude 非 DTD 环境注入
SVG/DOCX XXE 文件上传触发

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 XXE 读取当前目标之外的系统文件
  • 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 DTD 被禁用,尝试 XInclude、SVG/XSLT 中嵌入实体
  • 如果 外部实体被阻止,尝试参数实体、本地 DTD 覆盖
  • 如果 无回显,盲 XXE + OOB HTTP/FTP/DNS 外带
  • 如果 XML 解析器严格,尝试编码变体(UTF-16/UTF-7)、BOM 头
  • 如果 所有 XML 入口均安全,回退到上级知识库重新选择测试方向
  • DTD 被禁 → XInclude → SVG 上传 → 盲 XXE OOB → 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 XXE payload XML)
  • 实体解析证明(文件内容/SSRF 回调/OOB 数据)
  • 可读取范围评估(文件系统/内网/云元数据)

无法证明漏洞时,提交 negative report:已测试 XML 入口列表 + 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"。

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
