CVE-2018-15661
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 · uneditedAn issue was discovered in the Ola Money (aka com.olacabs.olamoney) application 1.9.0 for Android. If an attacker controls an application with accessibility permissions and the ability to read SMS messages, then the Forgot Password screen can be used to bypass authentication. NOTE: the vendor does not agree that this is a security issue requiring a fix
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 confidenceThe Ola Money Android application (v1.9.0) contains an authentication bypass vulnerability in its Forgot Password flow. An attacker controlling a malicious Android application with both accessibility service permissions and SMS read permissions can intercept and manipulate the password reset process to gain unauthorized access to the victim's Ola Money account.

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 Ola Money app versionCheck installed Ola Money version via Settings > Apps > Ola Money, or use 'adb shell dumpsys package com.olacabs.olamoney' to query package detailsAffected if Version is exactly 1.9.0 (only this specific version is affected)
-
Review granted accessibility service permissionsNavigate to Settings > Accessibility > Running Services, or use 'adb shell dumpsys accessibility' to list all services with accessibility permissions enabledAffected if Any untrusted or unfamiliar app has accessibility service permission granted (attack requires this permission)
-
Review granted SMS read permissionsCheck Settings > Apps > Permissions > SMS, or use 'adb shell dumpsys package <app>' to inspect READ_SMS permission grantsAffected if Any untrusted or unfamiliar app has READ_SMS permission granted (attack requires this permission)
-
Identify apps with both permission typesCross-reference apps with accessibility permissions against apps with SMS permissions; examine package names for suspicious or unknown originsAffected if A single app possesses both accessibility service and READ_SMS permissions simultaneously
User is affected if Ola Money version 1.9.0 is installed AND a malicious app with both accessibility service and SMS read permissions exists on the same device.

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 dataThe fix requires implementing stronger validation in the Forgot Password flow to detect and block manipulation by accessibility services, and adding additional verification factors beyond SMS-based OTP to prevent relay attacks.
