attachment[N][existing]request body/article-saveThe article-save handler accepts an 'attachment[N][existing]' POST field which is concatenated with 'JPATH_SITE/' and passed to JFile::copy(). Lack of path sanitization allows an attacker to copy arbitrary files (e.g., /etc/passwd) into the /media/k2/attachments/ directory.CWE-22
