Proof Of Concept for CVE-2024-1874

Command Injection via Array-ish $command Parameter of proc_open() (bypass CVE-2024-1874 fix)

The CVE: In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, the fix for CVE-2024-1874 does not work if the command name includes trailing spaces. Original issue: when using proc_open() command with array syntax, due to insufficient escaping, if the arguments of the executed command are controlled by a malicious user, the user can supply arguments that would execute arbitrary commands in Windows shell.
