Mantisbt Cross-site Scripting

An XSS vulnerability in MantisBT before 2.25.5 allows remote attackers to attach crafted SVG documents to issue reports or bugnotes. When a user or an admin clicks on the attachment, file_download.php opens the SVG document in a browser tab instead of downloading it as a file, causing the JavaScript code to execute. (2022-06-24, CVE-2022-33910)

An XSS issue was discovered in browser_search_plugin.php in MantisBT before 2.25.2. Unescaped output of the return parameter allows an attacker to inject code into a hidden input field. (2022-05-04, CVE-2022-28508)

An XSS issue was discovered in MantisBT before 2.25.3. Improper escaping of a Plugin name allows execution of arbitrary code (if CSP allows it) in manage_plugin_page.php and manage_plugin_uninstall.php when a crafted plugin is installed. (2022-04-13, CVE-2022-26144)

An XSS issue was discovered in manage_custom_field_edit_page.php in MantisBT before 2.25.2. Unescaped output of the return parameter allows an attacker to inject code into a hidden input field. (2021-06-17, CVE-2021-33557)

An issue was discovered in MantisBT through 2.24.3. In the helper_ensure_confirmed call in manage_custom_field_update.php, the custom field name is not sanitized. This may be problematic depending on CSP settings. (2021-02-22, CVE-2020-35571)

An issue was discovered in MantisBT before 2.24.3. Improper escaping of a custom field's name allows an attacker to inject HTML and, if CSP settings permit, achieve execution of arbitrary JavaScript when attempting to update said custom field via bug_actiongroup_page.php. (2020-09-30, CVE-2020-25830)

An issue was discovered in MantisBT before 2.24.3. When editing an Issue in a Project where a Custom Field with a crafted Regular Expression property is used, improper escaping of the corresponding form input's pattern attribute allows HTML injection and, if CSP settings permit, execution of arbitrary JavaScript. (2020-09-30, CVE-2020-25288)

An XSS issue was discovered in MantisBT before 2.24.2. Improper escaping on view_all_bug_page.php allows a remote attacker to inject arbitrary HTML into the page by saving it into a text Custom Field, leading to possible code execution in the browser of any user subsequently viewing the issue (if CSP settings allow it). (2020-08-12, CVE-2020-16266)

The proj_doc_edit_page.php Project Documentation feature in MantisBT before 2.21.3 has a stored cross-site scripting (XSS) vulnerability, allowing execution of arbitrary code (if CSP settings permit it) after uploading an attachment with a crafted filename. The code is executed when editing the document's page. (2020-03-19, CVE-2019-15539)

The Timeline feature in my_view_page.php in MantisBT through 2.21.1 has a stored cross-site scripting (XSS) vulnerability, allowing execution of arbitrary code (if CSP settings permit it) after uploading an attachment with a crafted filename. The code is executed for any user having visibility to the issue, whenever My View Page is displayed. (2019-08-21, CVE-2019-15074)

A cross-site scripting (XSS) vulnerability in the View Filters page (view_filters_page.php) and Edit Filter page (manage_filter_edit_page.php) in MantisBT 2.1.0 through 2.17.0 allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted PATH_INFO. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-13055. (2019-06-20, CVE-2018-16514)

A cross-site scripting (XSS) vulnerability in the Edit Filter page (manage_filter_edit page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name. (2018-10-30, CVE-2018-17783)

A cross-site scripting (XSS) vulnerability in the Manage Filters page (manage_filter_page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name. (2018-10-30, CVE-2018-17782)

A cross-site scripting (XSS) vulnerability in the View Filters page (view_filters_page.php) in MantisBT 2.1.0 through 2.15.0 allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted PATH_INFO. (2018-08-03, CVE-2018-13055)

An issue was discovered in manage_filter_edit_page.php in MantisBT 2.x through 2.15.0. A cross-site scripting (XSS) vulnerability in the Edit Filter page allows execution of arbitrary code (if CSP settings permit it) when displaying a filter with a crafted name (e.g., 'foobar" onclick="alert(1)'). (2018-08-03, CVE-2018-14504)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
