Web SERVER software (not app-layer) attack techniques — server misconfigs, known server CVEs, path traversal, exposed status/config. Use when you fingerprint the web server itself (for app-layer bugs use the web- skills). Triggers - Server header, Apache 2.4.49/2.4.50, nginx alias traversal, IIS, Tomcat…

Broken access control - IDOR, privilege escalation, JWT abuse, mass assignment, forced browsing - for web apps and APIs. Use on any multi-user or role-based app with object IDs, tokens, or admin functionality. Triggers - /api/users/ , /orders/ , ?account=/uid=/doc=, JWT (eyJ...), role/isAdmin field, admin panel, "403…

Insecure deserialization to RCE for web apps. Use when the app deserializes attacker-controlled data - cookies/tokens/hidden fields/params that are serialized blobs, VIEWSTATE, Java/PHP/.NET/Python/Node apps. Triggers - base64 starting rO0AB or hex AC ED 00 05 (Java), PHP serialize O-prefix, VIEWSTATE, python pickle…

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.
Skill Claude CodeCodex
SQL injection detection→exploitation→proof for web apps and APIs. Use when a parameter reaches a DB query, when input triggers a SQL error / boolean or time differential, or during VULN-ASSESSMENT/EXPLOITATION on a web target. Triggers - sql syntax error, ORA-/MySQL/psql/SQLite error string, ' or 1=1, order by…

Server-Side Request Forgery detection→internal-access→proof for web apps. Use when the app fetches a URL you influence (webhooks, url/image/pdf fetchers, link preview, import-from-URL, SSO/OIDC redirect, XML/SVG). Triggers - url=/uri=/dest=/callback= param, "fetch failed", webhook, image proxy, /next/image…
Skill Claude CodeCodex
Server-Side Template Injection detection→engine-fingerprint→RCE for web apps. Use when user input renders into a server-side template (names, greetings, email/PDF/report generators, error pages, profile fields) and math payloads evaluate. Triggers - {{77}} returns 49, ${77}.
Skill Claude CodeCodex
File-upload abuse to code execution for web apps. Use when the app accepts a file (avatar, document, image, import, attachment) and you can influence name/type/content, or find where uploads land. Triggers - multipart upload form, avatar/profile picture, import/attachment, "invalid file type", uploaded file URL…
Skill Claude CodeCodex
XML External Entity injection detection→file-read/SSRF→proof for web apps. Use when the app parses XML you influence - SOAP/REST XML bodies, SAML, RSS/Atom, DOCX/XLSX/SVG/XML file uploads, sitemap import, SVG avatars. Triggers - Content-Type application/xml or text/xml, <?xml, SOAPAction header, SAMLResponse…
