What is CVE-2023-54338?

Tftpd32 SE version 4.60 is vulnerable due to an unquoted service path that allows local attackers to execute arbitrary code with higher privileges. This flaw can be exploited when the service configuration does not encapsulate the executable path in quotes, enabling attackers to insert malicious scripts or executables. If exploited, the injected code runs with system-level permissions, posing a significant security risk. Users must apply recommended patches and security best practices to mitigate this vulnerability.
