CVE-2013-3935
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 Opsview before 4.4.1 and Opsview Core before 20130522 allows remote attackers to hijack the authentication of administrators for requests that change the administrator password via unspecified vectors.
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 confidenceCSRF vulnerability in Opsview and Opsview Core allows remote attackers to hijack administrator authentication and change admin passwords via forged requests. The vulnerability exists in the password change functionality which lacks proper anti-CSRF token validation.

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 Opsview versionLocate the installed Opsview version through the web interface (typically in 'About' or 'System Info' section) or by checking the package manager if you have CLI access. Compare this version against the affected ranges: Opsview < 4.4.1 or Opsview Core < 20130522.Affected if The installed version is Opsview below 4.4.1 or Opsview Core before 20130522.
-
Verify password change form includes anti-CSRF tokenAccess the admin password change form in the Opsview web interface (typically under Administration > Users or Profile settings). Inspect the HTML source of the form to determine if a hidden CSRF token field is present and submitted with the password change request.Affected if The password change form lacks a CSRF token field or the submitted token is not validated server-side.
-
Test token validation on password change endpointSubmit a password change request without the expected CSRF token (either by removing the token field or using an invalid token value) and observe whether the request is processed or rejected.Affected if Password change requests succeed without a valid CSRF token, indicating the anti-CSRF protection is not enforced.
-
Check Referer/Origin header validationAttempt a password change request with a missing or mismatched Referer/Origin header to see if the application rejects the request.Affected if The application accepts password change requests without validating the Referer or Origin headers, allowing cross-origin forged requests.
A user is affected if their Opsview version is below 4.4.1 (or Opsview Core before 20130522) AND the password change form lacks anti-CSRF token validation, allowing unauthorized admin password modifications.

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 data4.4.120130522
Upgrade to Opsview 4.4.1 or Opsview Core 20130522 or later. Additionally, implement anti-CSRF tokens on all state-changing forms including password change, validate Origin/Referer headers, and consider SameSite cookie attributes.
