https://www.synacktiv.com/sites/default/files/2023-01/sudo-CVE-2023-22809.pdf
・ CVE-2023-22809:sudoedit中存在一个有意思的逻辑漏洞,sudoedit通过sudo_edith函数中’–‘来判断文件列表进而影响执行的command_details,同时find_editorh函数会从EDITOR,SUDO_EDITOR,EDITOR环境变量中提取信息,并且调用resolve_editor函数进行解析,resolve_editor函数既解析了编辑器的路径,还解析了以’–‘为分割的参数.而如果在环境变量中加入’–‘,则在最后的执行命令中造成了命令行的混淆,让sudo认为”–”参数之后的所有内容都视为要编辑的文件.从而可以利用这个漏洞去编辑任意敏感文件以达到提权的目的
