NamelessMC is a free, easy to use & powerful website software for Minecraft servers. Cross-site scripting (XSS) vulnerability in NamelessMC before 2.2.4 allows remote authenticated attackers to inject arbitrary web script or HTML via the default_keywords crafted parameter. This vulnerability is fixed in 2.2.4.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. Sensitive information disclosure in NamelessMC before 2.2.4 allows unauthenticated remote attacker to gain sensitive information such as absolute path of the source code via list parameter. This vulnerability is fixed in 2.2.4.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. Cross-site scripting (XSS) vulnerability in NamelessMC before 2.2.3 allows remote authenticated attackers to inject arbitrary web script or HTML via the dashboard text editor component. This vulnerability is fixed in 2.2.4.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. Prior to version 2.1.4, NamelessMC is vulnerable to SQL injection by providing an unexpected square bracket GET parameter syntax. Square bracket GET parameter syntax refers to the structure `?param[0]=a&param[1]=b&param[2]=c` utilized by PHP, which is parsed by PHP as `$_GET['param']` being of type array. This issue has been patched in version 2.1.4.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, an insecure view count mechanism in the forum page allows an unauthenticated attacker to artificially increase the view count. The application relies on a client-side cookie (nl-topic-[tid]) (or session variable for guests) to determine if a view should be counted. When a client does not provide the cookie, every page request increments the counter, leading to incorrect view metrics. This issue has been patched in version 2.2.0.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, forum quick reply feature (view_topic.php) does not implement any spam prevention mechanism. This allows authenticated users to continuously post replies without any time restriction, resulting in an uncontrolled surge of posts that can disrupt normal operations. This issue has been patched in version 2.2.0.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, if a malicious user is leaving spam comments on many topics then an administrator, unable to manually remove each spam comment, may delete the malicious account. Once an administrator deletes the malicious user's account, all their posts (comments) along with the associated topics (by unrelated users) will be marked as deleted. This issue has been patched in version 2.2.0.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, the forum allows users to post iframe elements inside forum topics/comments/feed with no restriction on the iframe's width and height attributes. This allows an authenticated attacker to perform a UI-based denial of service (DoS) by injecting oversized iframes that block the forum UI and disrupt normal user interactions. This issue has been patched in version 2.2.0.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, the s parameter in GET requests for forum search functionality lacks length validation, allowing attackers to submit excessively long search queries. This oversight can lead to performance degradation and potential denial-of-service (DoS) attacks. This issue has been patched in version 2.2.0.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. A user with admincp.core.emails or admincp.users.edit permissions can validate users and an attacker can reset their password. When the account is successfully approved by email the reset code is NULL, but when the account is manually validated by a user with admincp.core.emails or admincp.users.edit permissions then the reset_code will no longer be NULL but empty. An attacker can request http://localhost/nameless/index.php?route=/forgot_password/&c= and reset the password. As a result an attacker may compromise another users password and take over their account. This issue has been addressed in release version 2.1.3 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In affected versions an admin can add the ability to have users fill out an additional field and users can inject javascript code into it that would be activated once a staffer visits the user's profile on staff panel. As a result an attacker can execute javascript code on the staffer's computer. This issue has been addressed in version 2.1.3 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
