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 installed product versionIdentify the installed version of Abeltechsoft Chavara Matrimony on your system. Check any version information displayed in the application UI, contained in configuration files, or listed in your software inventory.Affected if The installed version is Abeltechsoft Chavara Matrimony version 2.0 exactly.
-
Locate OTP login or registration functionalityDetermine if your instance has OTP (One-Time Password) authentication enabled for user login, registration, or password reset flows. This is typically found in the authentication modules or login pages.Affected if OTP verification is actively used or configured in your environment.
-
Test OTP endpoint for validation bypassSubmit a crafted OTP request to the OTP verification endpoint (commonly /otp/verify, /verify-otp, or similar). Observe if the system accepts invalid, expired, or manipulated OTP values without proper validation.Affected if The OTP endpoint accepts crafted or manipulated requests and grants access without validating the OTP properly.
You are affected if you are running Abeltechsoft Chavara Matrimony v2.0 and have OTP authentication enabled, with the OTP verification endpoint vulnerable to bypass via crafted requests.

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 proper server-side OTP validation that cannot be bypassed through crafted requests, including validating OTP freshness, binding OTP to session, and rejecting replayed or manipulated OTP submissions.
