CWE-31 Path Traversal with 'dir\\..\\..\\filename' Explained
Removing one backslash dot-dot sequence is not enough when the attacker sends two. How CWE-31 defeats single-pass filters and how to resolve paths safely.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.

Passwords as the main login have known shortcomings. See what MITRE says to do about storage, aging, strength and zero-knowledge options.
When one stolen secret equals full access, a leak ends the game. Learn where single-factor design hurts most and how independent factors limit the damage.
Without limits on failed logins, guessing passwords is just a matter of time. See the common gaps, how to test for them and which controls actually slow attackers.
Endpoints, ports and protocols that never ask who is calling hand attackers whatever privilege the function has. Find them, protect every channel and fix them for good.
The algorithm is fine but a separate flaw, such as comparing one character of a password, lets attackers walk past it. See the real cases and how to test for them.
Authentication methods only work if every step runs. Learn how skipped verification steps allow bypass and spoofed replies, and how to test for them.
Choosing a sound authentication algorithm is not enough if the code gets it wrong. See how one flipped condition can open the door and how to guard against it.
Cookies, hidden form fields and environment variables can all be changed by the caller. Learn how treating them as fixed leads to login bypass and how to stop it.
