Codoforum Cross-site Scripting

A stored cross site scripting (XSS) vulnerability in the 'Manage Users' feature of Codoforum v5.0.2 allows authenticated attackers to execute arbitrary web scripts or HTML via a crafted payload entered into the 'Username' parameter. (2021-07-09, CVE-2020-25879)

A stored cross site scripting (XSS) vulnerability in the 'Pages' feature of Codoforum v5.0.2 allows authenticated attackers to execute arbitrary web scripts or HTML via crafted payload entered into the 'Page Title' parameter. (2021-07-09, CVE-2020-25876)

A stored cross site scripting (XSS) vulnerability in the 'Smileys' feature of Codoforum v5.0.2 allows authenticated attackers to execute arbitrary web scripts or HTML via crafted payload entered into the 'Smiley Code' parameter. (2021-07-09, CVE-2020-25875)

Codoforum 4.8.3 allows HTML Injection in the 'admin dashboard Manage users Section.' (2020-09-14, CVE-2020-21845)

Codoforum 4.8.8 allows self-XSS via the title of a new topic. (2020-02-16, CVE-2020-9007)

Codologic Codoforum through 4.8.4 allows a DOM-based XSS. While creating a new topic as a normal user, it is possible to add a poll that is automatically loaded in the DOM once the thread/topic is opened. Because session cookies lack the HttpOnly flag, it is possible to steal authentication cookies and take over accounts. (2020-02-15, CVE-2020-7050)

Codologic Codoforum through 4.8.4 allows stored XSS in the login area. This is relevant in conjunction with CVE-2020-5842 because session cookies lack the HttpOnly flag. The impact is account takeover. (2020-02-13, CVE-2020-7051)

Codoforum 4.8.3 allows XSS in the user registration page: via the username field to the index.php?u=/user/register URI. The payload is, for example, executed on the admin/index.php?page=users/manage page. (2020-01-07, CVE-2020-5842)

Codoforum 4.8.3 allows XSS in the admin dashboard via a category to the Manage Users screen. (2020-01-07, CVE-2020-5843)

Codoforum 4.8.3 allows XSS in the admin dashboard via a name field of a new user, i.e., on the Manage Users screen. (2020-01-05, CVE-2020-5305)

Codoforum 4.8.3 allows XSS via a post using parameters display name, title name, or content. (2020-01-05, CVE-2020-5306)

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>
