Mantis Bug Tracker (MantisBT) allows user account takeover in the signup/reset password process
Insufficient access control in the registration and password reset process allows an attacker to reset another user's password and takeover their account, if the victim has an incomplete request pending.

The exploit is only possible while the verification token is valid, i.e for 5 minutes after the confirmation URL sent by e-mail has been opened, and the user did not complete the process by updating their password.

A brute-force attack calling account_update.php with increasing user IDs is possible.

MantisBT HTML Injection vulnerability
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`.

MantisBT Remote Code Execution
MantisBT before 1.3.20 and 2.22.1 allows Post Authentication Command Injection, leading to Remote Code Execution.

MantisBT cross-site scripting (XSS) vulnerability through crafted PATH_INFO
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.

MantisBT Missing Authorization access check in bug_actiongroup.php
An issue was discovered in MantisBT before 2.24.4. A missing access check in bug_actiongroup.php allows an attacker (with rights to create new issues) to use the COPY group action to create a clone, including all bugnotes and attachments, of any private issue (i.e., one having Private view status, or belonging to a private Project) via the bug_arr[] parameter. This provides full access to potentially confidential information.

MantisBT allows XSS via Edit Filter page
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.

MantisBT is vulnerable to authentication bypass through the SOAP API on MySQL
Mantis Bug Tracker instances running on MySQL and compatible databases are affected by an authentication bypass vulnerability in the SOAP API, as a result of improper type checking on the password parameter.

Other database backends are not affected, as they do not perform implicit type conversion from string to integer.

### Impact
Using a crafted SOAP envelope, an attacker knowing the victim's username is able to login to the SOAP API with their account without knowledge of the actual password, and execute any API function they have access to.

### Patches
* b349e5c890eeda9bd82e7c7e14479853f8a30d9f

### Workarounds
- [Disabling the SOAP API](https://mantisbt.org/docs/master/en-US/Admin_Guide/html-desktop/#admin.config.api.disable) significantly reduces the risk, but still allows the attacker to retrieve user account information including email address and real name.

### Credits
MantisBT thanks Alexander Philiotis of SynerComm for discovering and responsibly reporting the issue.

MantisBT vulnerable to information disclosure with user profiles
Using a crafted POST request, an unprivileged, registered user is able to retrieve information about other users' personal system profiles.

MantisBT XSS when uploading an attachment
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.

MantisBT Incorrect Authorization for bug_revision_view_page.php check
An issue was discovered in MantisBT before 2.24.4. An incorrect access check in bug_revision_view_page.php allows an unprivileged attacker to view the Summary field of private issues, as well as bugnotes revisions, gaining access to potentially confidential information via the bugnote_id parameter.

MantisBT lacks verification when changing a user's email address
When a user edits their profile to change their e-mail address, the system saves it without validating that it actually belongs to the user.

MantisBT Vulnerable to Denial-of-Service (DoS) via Excessive Note Length
A lack of server-side validation for note length in MantisBT allows attackers to permanently corrupt issue activity logs by submitting extremely long notes (tested with 4,788,761 characters). Once such a note is added:

MantisBT allows XSS on the Edit Filter page via crafted filter name
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)').

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
MantisBT is an open source issue tracker. Prior to version 2.26.1, an unauthenticated attacker who knows a user's email address and username can hijack the user's account by poisoning the link in the password reset notification message. A patch is available in version 2.26.1. As a workaround, define `$g_path` as appropriate in `config_inc.php`.
