CVE-2025-9176

Local command execution via unquoted CC variable

Published Aug 19, 2025 · Updated Aug 20, 2025

Command injection in Neurobin SHC 4.0.0 through 4.0.3 allows local users to execute shell commands through the CC variable. The make() function in generated hardened executables reads CC, embeds it unquoted in a compiler command with sprintf(), and passes the string to system(). Exploitation requires local execution of a binary produced with hardening enabled and runs injected shell commands with that binary's privileges.
