CVE-2023-38885
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 · uneditedOpenSIS Classic Community Edition version 9.0 lacks cross-site request forgery (CSRF) protection throughout the whole app. This may allow an attacker to trick an authenticated user into performing any kind of state changing request.
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 confidenceOpenSIS Classic Community Edition v9.0 lacks cross-site request forgery (CSRF) protection across the entire application. The absence of anti-CSRF tokens or other CSRF mitigations allows authenticated users to be tricked into unknowingly executing state-changing requests via maliciously crafted links or pages.

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 OpenSIS versionCheck the installed OpenSIS version by accessing the admin panel or examining version.php in the installation directoryAffected if Version is exactly 9.0 (Os4ed Opensis)
-
Inspect login and form submissions for anti-CSRF tokensExamine the HTML source of state-changing pages (login, profile update, data entry forms) and search for hidden input fields named like 'token', 'csrf', or 'nonce'Affected if No anti-CSRF tokens are present in forms that perform state-changing operations
-
Check cookie headers for SameSite attributeUse browser dev tools or a proxy to inspect Set-Cookie headers from the OpenSIS server and verify if SameSite attribute is set to 'Strict' or 'Lax'Affected if Cookies do not have SameSite attribute configured or it is set to 'None' without Secure flag
-
Test state-changing endpoints for CSRF vulnerabilityCreate a test HTML page with a form that submits a state-changing request to OpenSIS without a token, then attempt to submit it and observe if the action executesAffected if The state-changing action succeeds without requiring a valid anti-CSRF token or referer validation
The environment is affected if running OpenSIS version 9.0 and state-changing operations lack anti-CSRF tokens or SameSite cookie 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 synchronizer token pattern (anti-CSRF tokens) for all state-changing operations and configure SameSite cookie attributes to prevent CSRF attacks.
