Hence, all output that is dynamically generated based on user-controlled data should be encoded according to its context. The majority of programming languages support standard procedures for encoding meta characters. For example, PHP has the built-in function htmlspecialchars().<\/span><br \/><span>Additionally, all input should be validated on the server-side. Where possible, whitelist filters should be used. The more restrictive a filter can be specified, the better the protection it provides. Whitelisting is especially recommended if input values have a well defined format or a list of valid input values exists. Invalid values should not be sanitized and forwarded to the application. Instead, requests with invalid values should be rejected.<\/span><\/p>\n<h3><\/h3>\n<h3>Timeline<\/h3>\n<ul>\n<li>2020-06-18 First contact request via security@getgophish.com<\/li>\n<li>2020-06-22 Vendor responds to initial contact<\/li>\n<li>2020-07-18 Vendor fixes vulnerability <a href=\"https:\/\/github.com\/gophish\/gophish\/commit\/4e9b94b641755f359542b246cc0c555fa3bc6715\" target=\"_blank\" rel=\"noopener\">https:\/\/github.com\/gophish\/gophish\/commit\/4e9b94b641755f359542b246cc0c555fa3bc6715<\/a><\/li>\n<li>2020-09-29 Security advisory released<\/li>\n<\/ul>\n<h3><\/h3>\n<h3>Credits<\/h3>\n<p><span>This security vulnerability was found by Marcus Nilsson of usd AG.<\/span><\/p>\n<\/div>\n<\/div>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>usd-2020-0050 | Gophish v0.10.1 Advisory ID: usd-2020-0050CVE Number: CVE-2020-24712Affected Product: GophishAffected Version: v0.10.1Vulnerability Type: non-persistent self Cross-Site ScriptingSecurity Risk: LowVendor URL: https:\/\/getgophish.com\/Vendor Status: Fixed Description The \u201cIMAP Host\u201c input field is vulnerable to Self-XSS when combined with pressing the \u201cTest Settings\u201c button.
