Security researchers have discovered a critical heap buffer overflow vulnerability in NGINX that has existed since 2008, allowing potential remote code execution. The flaw, found using autonomous code analysis, affects configurations using rewrite and set directives. A proof-of-concept exploit has been developed demonstrating RCE with ASLR disabled, posing significant risk to the widely-used web server.
Background
NGINX is the world's most popular web server, powering nearly one-third of all websites globally, making any vulnerability in its codebase particularly critical for internet infrastructure security.
