  • GHSA-7w4p-72j7-v7c2Phar object injection in PHPMailer2020-03-05ghsa · osvUS

    PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing phar:// paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr. ### Impact Object injection, possible remote code execution ### Patches Fixed in 6.0.6 and 5.2.27 ### Workarounds Validate and sanitise user input before using. ### References https://nvd.nist.gov/vuln/detail/CVE-2018-19296 ### For more information If you have any questions or comments about this advisory: * Open a private issue in [the PHPMailer project](https://github.com/PHPMailer/PHPMailer)
