- Summary
- Local file disclosure in PHPMailer
- Details
-
An issue was discovered in PHPMailer before 5.2.22. PHPMailer's
msgHTMLmethod applies transformations to an HTML document to make it usable as an email message body. One of the transformations is to convert relative image URLs into attachments using a script-provided base directory. If no base directory is provided, it resolves to/, meaning that relative image URLs get treated as absolute local file paths and added as attachments. To form a remote vulnerability, the msgHTML method must be called, passed an unfiltered, user-supplied HTML document, and must not set a base directory.Impact
Arbitrary local files can be attached to email messages.
Patches
Fixed in 5.2.22
Workarounds
Validate input before using user-supplied file paths.
