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.
CWE-284 is the top level weakness for failing to restrict access to a resource. Learn the specification versus enforcement split, real CVEs, and a review method.
CWE-283 is trusting a critical resource without checking its owner. A socket or device owned by the wrong user can undo your authentication.
CWE-282 covers assigning the wrong owner to an object, or failing to verify who owns it. Learn why setuid programs and config files make this dangerous.
CWE-281 covers copy, restore, and share operations that loosen permissions. Learn how backups and clones expose files and how to preserve modes safely.
CWE-280 is a program that mishandles being denied access and lands in an invalid state. See the examples and the fail-safe fix.
Backslash dot-dot sequences are the native traversal on Windows and a bypass elsewhere. How CWE-28 works, with observed cases and a fix that handles both separators.
CWE-279 covers programs that set object permissions at runtime in a way that overrides what the user asked for. The classic case is log files opened read and write.
CWE-278 is when a program silently keeps unsafe permissions from a source such as an archive. See how it happens and how to extract files safely.
CWE-277 is when objects a program creates inherit insecure permissions, such as the user's umask on temp files. Learn how to set modes on purpose.
