Exploit › Module 8 › Lesson 4
Lab — History
History and CVE lab — historic table, one CVE worksheet, patch mindset applied to YOUR $PWN_LAB toy rebuild.
Visual · t24_history_lab
Lab: history + CVE + patch on $PWN_LAB. Original Cyberlium.
Opening
Connect a famous CVE class to a fix you applied on your toy — history that changes how you compile.
Complete: (1) historic bugs table ≥3 rows from Lesson 8-1; (2) CVE reading worksheet on one patched memory-safety CVE (no PoC); (3) patch mindset checklist signed; (4) on $PWN_LAB rebuild one toy with Module 5 safer flags after mapping toy bug class to CVE class analogy; (5) before/after checksec note; (6) chmod 600 pack. No worm replay, no internet scanning for vulns, no exploit-from-CVE homework. Gap note: how finding feeds Module 9 report.
1. Lab deliverables
Historic table + CVE worksheet + patch checklist + toy rebuild log with hashes.

evidence: NVD/CWE pages fetched + hash of YOUR vuln toy for change tracking
scope: literacy — no public exploit PoC attached

Primary tools to practice this lesson: curl, grep, openssl. Reference sites: NVD search (https://nvd.nist.gov/vuln/search); CWE-119 (https://cwe.mitre.org/data/definitions/119.html); Microsoft SDL (https://learn.microsoft.com/en-us/security/sdl/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Toy rebuild evidence
Before/after SHA256, flags added (-fstack-protector-strong, -D_FORTIFY_SOURCE, sanitizer if brief allows).
Re-run crash repro from Module 6 — expect canary/abort instead of silent segfault if fixed.
3. Integrity
No exploit PoC from CVE references; literacy and remediation only.
Honest N/A if CVE is unrelated to toy — state analogy limits.
4. What you ship: history lab pack
Historic + CVE + patch + toy rebuild evidence — chmod 600.
5. What you record before the next lesson
History lab pack path.
6. Wrong vs right: weaponized exploits vs memory-safety literacy
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
History lab includes scanning campus for CVE hosts.
Right
History lab pack completed on $PWN_LAB. Next: quiz.
Mission: history lab
1) Historic table three rows. 2) CVE worksheet no PoC. 3) Rebuild toy with safer flags. 4) Before/after checksec; chmod 600.
