GetSimple CMS & GetSimpleCMS-CE have an Unauthenticated Admin Account Creation via Setup Logic Flaw

GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. A logic flaw in GetSimple CMS (v3.4.0a and below) and GetSimpleCMS-CE (v3.3.22 and below) allows unauthenticated attackers to create a new administrator account. The application features an automated security control designed to delete the sensitive `admin/setup.php` file post-installation. However, this control is neutralized by a self-exclusion bug within the deletion logic, leaving the setup script accessible for unauthorized account creation even after a legitimate installation is completed. As of time of publication, no known patched versions are available.

GetSimpleCMS-CE < 3.3.22 Stored XSS via components.php

GetSimpleCMS Community Edition (CE) versions prior to 3.3.22 (3.3.16 tested) contains a stored cross-site scripting (XSS) vulnerability in the Theme to Components functionality within components.php. User-supplied input provided to the "slug" field of a component is stored without proper output encoding. While other fields are sanitized using safe_slash_html(), the slug parameter is written to XML and later rendered in the administrative interface without sanitation, resulting in persistent execution of arbitrary JavaScript. An authenticated administrator can inject malicious script content that executes whenever the affected Components page is viewed by any authenticated user, enabling session hijacking, unauthorized administrative actions, and persistent compromise of the CMS administrative interface.

GetSimple CMS My SMTP Contact Plugin 1.1.2 - Stored XSS

GetSimple CMS My SMTP Contact Plugin 1.1.2 suffers from a Stored Cross-Site Scripting (XSS) vulnerability. The plugin attempts to sanitize user input using htmlspecialchars(), but this can be bypassed by passing dangerous characters as escaped hex bytes. This allows attackers to inject arbitrary client-side code that executes in the administrator's browser when visiting a malicious page.

GetSimple CMS Custom JS 0.1 - CSRF to XSS to RCE

GetSimple CMS Custom JS 0.1 plugin contains a cross-site request forgery vulnerability that allows unauthenticated attackers to inject arbitrary client-side code into administrator browsers. Attackers can craft a malicious website that triggers a cross-site scripting payload to execute remote code on the hosting server when an authenticated administrator visits the page.

GetSimple CMS My SMTP Contact Plugin 1.1.1 - CSRF

GetSimple CMS My SMTP Contact Plugin 1.1.1 contains a cross-site request forgery (CSRF) vulnerability. Attackers can craft a malicious webpage that, when visited by an authenticated administrator, can change SMTP configuration settings in the plugin. This may allow unauthorized changes but does not directly enable remote code execution.

GetSimple CMS v3.3.16 was discovered to contain a remote code execution (RCE) vulnerability via the edited_file parameter in admin/theme-edit.php.

GetSimple CMS 3.3.4 allows remote attackers to obtain sensitive information via a direct request to (1) data/users/<username>.xml, (2) backups/users/<username>.xml.bak, (3) data/other/authorization.xml, or (4) data/other/appid.xml.

GetSimple CMS 3.3.4 allows remote attackers to obtain sensitive information via a direct request to (1) plugins/anonymous_data.php or (2) plugins/InnovationPlugin.php, which reveals the installation path in an error message.

admin/profile.php in GetSimple CMS 3.x has XSS in a name field.

GetSimple CMS Content Module edit.php cross site scripting

A vulnerability, which was classified as problematic, has been found in GetSimple CMS. Affected by this issue is the file /admin/edit.php of the Content Module. The manipulation of the argument post-content with an input like <script>alert(1)</script> leads to cross site scripting. The attack may be launched remotely but requires authentication. Expoit details have been disclosed within the advisory.

Multiple cross-site scripting (XSS) vulnerabilities in GetSimple CMS before 3.3.6 allow remote attackers to inject arbitrary web script or HTML via the (1) post-content or (2) post-title parameter to admin/edit.php.

Multiple cross-site scripting (XSS) vulnerabilities in GetSimple CMS 3.3.1 allow remote attackers to inject arbitrary web script or HTML via the (1) param parameter to admin/load.php or (2) user, (3) email, or (4) name parameter in a Save Settings action to admin/settings.php.

XML external entity (XXE) vulnerability in admin/api.php in GetSimple CMS 3.1.1 through 3.3.x before 3.3.5 Beta 1, when in certain configurations, allows remote attackers to read arbitrary files via the data parameter.

Cross-site scripting (XSS) vulnerability in admin/filebrowser.php in GetSimple CMS before 3.3.6 allows remote attackers to inject arbitrary web script or HTML via the func parameter.

Multiple cross-site scripting (XSS) vulnerabilities in GetSimple CMS 3.1.2 and 3.2.3 allow remote attackers to inject arbitrary web script or HTML via the (1) post-menu field to edit.php or (2) Display name field to settings.php. NOTE: The Custom Permalink Structure and Email Address fields are already covered by CVE-2012-6621.

Cross-site scripting (XSS) vulnerability in admin/changedata.php in GetSimple CMS 2.01 allows remote attackers to inject arbitrary web script or HTML via the post-title parameter.

Multiple cross-site scripting (XSS) vulnerabilities in GetSimple CMS 3.1, 3.1.2, 3.2.3, and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) Email Address or (2) Custom Permalink Structure fields in admin/settings.php; (3) path parameter to admin/upload.php; (4) err parameter to admin/theme.php; (5) error parameter to admin/pages.php; or (6) success or (7) err parameter to admin/index.php.

Cross-site scripting (XSS) vulnerability in admin/components.php in GetSimple CMS 2.01 allows remote attackers to inject arbitrary web script or HTML via the val[] parameter.

GetSimple CMS 3.3.16 allows in parameter 'permalink' on the Settings page persistent Cross Site Scripting which is executed when you create and open a new page

A Reflected Cross-Site Scripting (XSS) vulnerability in GetSimple CMS v3.3.16, in the admin/index.php login portal webpage, allows remote attackers to execute JavaScript code in the client's browser and harvest login credentials after a client clicks a link, enters credentials, and submits the login form.
