Name of the Vulnerable Software and Affected Versions nginx version 0.7.64

Description The issue allows remote attackers to potentially modify a window's title, execute arbitrary commands, or overwrite files via an HTTP request containing an escape sequence for a terminal emulator. This is because nginx writes data to a log file without sanitizing non-printable characters.

Recommendations For nginx version 0.7.64, update to a version that sanitizes non-printable characters in log files to prevent potential exploitation.
