Grav is a flat-file content management system. This allows an attacker to execute code of their choice on an affected host by copying carefully selected data that will be executed as code. An overly large value for certain options of a connection string may overrun the buffer allocated to process the string value. Version 5.3.0 contains a patch for this issue.Ī buffer overflow was discovered in Progress DataDirect Connect for ODBC before for Oracle. get executed by the system via cron or requests.
The attacker can also overwrite existing files and inject malicious code into files that, e.g. This allows an attacker to upload malicious code of any type and content at any location where the underlying user has write permissions. There is also no restriction about the file extension (e.g. by passing the name or filename of the mail attachment itself (from email headers), the input values never get sanitized by the package. Even if a developer passes a `$filename` into the `Attachment::save()` method, e.g. In this case, where no `$filename` gets passed into the `Attachment::save()` method, the package would use a series of unsanitized and insecure input values from the mail as fallback. Prerequisite for the vulnerability is that the script stores the attachments without providing a `$filename`, or providing an unsanitized `$filename`, in `src/Attachment::save(string $path, string $filename = null)`. An attacker can send an email with a malicious attachment to the inbox, which gets crawled with `webklex/php-imap` or `webklex/laravel-imap`. Every application that stores attachments with `Attachment::save()` without providing a `$filename` or passing unsanitized user input is affected by this attack. Prior to version 5.3.0, an unsanitized attachment filename allows any unauthenticated user to leverage a directory traversal vulnerability, which results in a remote code execution vulnerability. PHP-IMAP is a wrapper for common IMAP communication without the need to have the php-imap module installed / enabled.
