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-1294 is the class behind missing, mis-converted and mis-generated security identifiers in a System-on-Chip. What it covers and how to review for it.
Trust one data source and a single compromise or man in the middle can fake the answer. CWE-1293 explained, with a quorum sketch and what to report when sources disagree.
When a bridge converts bus signals to security identifiers badly, untrusted agents gain access to assets. A plain look at CWE-1292 and the review and test steps that address it.
If debug and production firmware verify against the same key, a leaked debug image runs on shipped devices. How CWE-1291 happens and a simple check to catch it.
A bus decoder that maps an untrusted agent to a trusted identity hands that agent access it should never have. Here is how CWE-1290 happens in an SoC and how teams catch it.
Untrusted values used as array indexes can read or write the wrong memory. See the pattern in C, what it enables, and how to validate indexes properly.
Input that looks safe to your check but means something dangerous downstream. CWE-1289 explained with case, encoding and extension examples, plus fixes in Python and JavaScript.
A packet says it has ten items and carries three. A range ends before it starts. Fields that must agree with each other need to be checked together.
An ID that should be a number, a digest that should be a hash. When the type is assumed rather than checked, injection and path traversal follow.
