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.
Lazarus used this afd.sys use-after-free to reach SYSTEM from a local foothold, then loaded a FudModule kernel rootkit. Escalation is never the objective — it is the step before it.
Progress Kemp LoadMaster's flaw lives inside escape_quotes(), the routine meant to neutralise dangerous input. It fails to null-terminate, turning a sanitiser into unauthenticated command injection.
An unauthenticated attacker sends a crafted object to TeamCity's agent polling endpoint and gets OS command execution as the server process. Every credential the build server holds sits downstream.
Langflow's auto-login endpoint mints a superuser token for anyone who asks. Its code-validation endpoint runs Python through exec(). Chained, that is unauthenticated RCE at CVSS 9.8.
CVE-2022-40897 is a ReDoS flaw in setuptools' package_index.py that can hang CI pipelines when parsing crafted index pages. Here's how to detect and fix it.
