CVE-2024-51736

Local code execution via relative cmd.exe lookup

Published Nov 6, 2024 · Updated Nov 21, 2024

Command hijacking in Symfony Process before 5.4.46, 6.0.0 through 6.4.13, and 7.0.0 through 7.1.6 allows local users to execute code. The Process class prepares Windows commands with a relative cmd.exe name, allowing the current directory to take precedence over PATH. Exploitation requires Windows and a planted cmd.exe in the process working directory; execution inherits the affected PHP process privileges.
