CVE-2010-0638
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 WebCalendar 1.2.0 allows remote attackers to hijack the authentication of administrators for requests that change the administrative password via unknown vectors. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
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 · moderate confidenceCross-site request forgery (CSRF) vulnerability in WebCalendar 1.2.0 allows remote attackers to hijack the authentication of administrators by tricking authenticated admin users into unknowingly submitting malicious requests that change the administrative password, effectively allowing the attacker to gain administrative access.

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.
-
Confirm WebCalendar installationIdentify if K5n WebCalendar is installed in your environment by checking for web calendar application files or running processesAffected if WebCalendar is present and accessible on the network
-
Identify installed versionCheck the version number of the WebCalendar installation - this is typically visible in the application header, about page, or version fileAffected if Version is 1.2.0 exactly
-
Verify admin interface is accessibleLocate the administrative login page (commonly at /admin or /login) and confirm you can access the authenticated admin panelAffected if Administrative interface is accessible and functional
-
Check password change form for CSRF protectionAccess the admin password change functionality and inspect the HTML form for the presence of anti-CSRF tokens (hidden input fields with random values) or examine server-side code for referer/origin header validationAffected if Password change form lacks anti-CSRF tokens and no referer/origin validation is performed server-side
You are affected if K5n WebCalendar version 1.2.0 is installed and the admin password change form lacks anti-CSRF token protection.

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 sensitive forms including password change functionality, validate Origin/Referer headers server-side, and require re-authentication for critical administrative actions like password modifications.
