CVE-2013-3269
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 Cybozu Office before 8.1.6 and 9.x before 9.3.0 allows remote attackers to hijack the authentication of arbitrary users for requests that change mobile passwords, a different vulnerability than CVE-2013-2305.

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.
-
Verify Cybozu Office is installedLocate Cybozu Office by checking for its installation directory (typically under C:\Program Files\Cybozu or /opt/cybozu on Linux) or by accessing the web interface on common ports (80/443). Confirm the product name in the application header or title.Affected if Cybozu Office is not found on the system
-
Identify the installed versionAccess the system settings or administration panel in Cybozu Office. The version information is typically found under 'System Settings' > 'System Information' or by accessing the /cgi-bin/cbgrn/cbgrn.exe?g=adm_menu URL pattern. Alternatively, check the about page or version.txt in the installation directory.Affected if The version is 6.x, 7.x, 8.x before 8.1.6, or 9.x before 9.3.0 (including 9.2.1)
-
Confirm mobile interface is enabledCheck if mobile access is available by attempting to access the mobile interface URL (typically /mobile/ or /sp/ path) or by reviewing the system settings for mobile device access under 'System Settings' > 'Mobile Settings'.Affected if Mobile interface is accessible and enabled for users
-
Verify CSRF protection on password changeAttempt to access the mobile password change function without a CSRF token. Submit a password change request via the mobile interface and inspect whether the application validates an anti-CSRF token (such as a session-bound token or referer check). Check the HTML source for a hidden token field in password change forms.Affected if No anti-CSRF token is present in the mobile password change form or the request is processed without token validation
A user is affected if Cybozu Office version is 6.x, 7.x, 8.x before 8.1.6, or 9.x before 9.3.0, and the mobile interface with password change functionality is enabled and lacks CSRF 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 dataApply vendor patches (Cybozu Office 8.1.6 or 9.3.0 and later) to implement anti-CSRF token validation for mobile password change operations.
