To resolve the CVE-2022-48624 vulnerability on Ubuntu using Nginx, it's crucial to understand that the issue lies within the "less" package, not Nginx itself. The vulnerability affects "less" before version 606, where close_altfile in filename.c in less omits shell_quote calls for LESSCLOSE, potentially allowing shell command injection.
The current less version is 551, which is vulnerable. You'll need to upgrade "less" to a version at or beyond 606.
