CVE-2010-3883
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCross-site request forgery (CSRF) vulnerability in the Change Group Permissions module in CMS Made Simple 1.7.1 and earlier allows remote attackers to hijack the authentication of arbitrary users for requests that make permission modifications.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCross-site request forgery (CSRF) vulnerability in CMS Made Simple's Change Group Permissions module allows remote attackers to trick authenticated administrators into unknowingly modifying group permissions. The attack exploits the lack of anti-CSRF tokens on permission modification forms, enabling unauthorized permission changes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify CMS Made Simple installation and versionLocate the CMS Made Simple installation directory and check the version file (typically version.php or similar in the installation root). Common paths include /var/www/html/cms or the web root where CMS Made Simple is installed.Affected if The installed version matches one of the affected versions: <= 1.7.1, or specifically 0.10, 0.10.3, 0.10.4, 0.11, 0.11.1, 0.11.2, 0.12, 0.12.1, 0.12.2, 0.13, or 1.0.
-
Verify Change Group Permissions module is enabledAccess the CMS Made Simple admin panel, navigate to the admin extensions or module management section, and confirm whether the 'Change Group Permissions' or 'Group Permissions' module is installed and active.Affected if The Change Group Permissions module is installed and enabled on the CMS installation.
-
Inspect permission modification forms for anti-CSRF tokensNavigate to the Change Group Permissions module in the admin interface, view the page source (or use browser dev tools) on the permission modification forms, and search for CSRF token fields such as 'csrf_token', 'csrf', 'token', or 'sec_token'.Affected if The forms for modifying group permissions lack any anti-CSRF token field, or the token field exists but is not validated server-side.
-
Confirm administrator authentication requirementVerify that the Change Group Permissions functionality is accessible only to authenticated administrators with appropriate permissions by checking the module's access control settings.Affected if The module requires administrator authentication but does not implement CSRF protection on state-changing actions.
A user is affected if they run CMS Made Simple version 1.7.1 or lower, have the Change Group Permissions module enabled, and the permission modification forms lack anti-CSRF token validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (synchronizer token pattern) on all forms in the Change Group Permissions module, including both the permission modification form and any related admin interfaces.
