CVE-2012-4918
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 · uneditedCall of Duty Elite for iOS 2.0.1 does not properly validate the server SSL certificate, which allows remote attackers to obtain sensitive information via a Man-in-the-Middle (MITM) attack.
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 Call of Duty Elite iOS application 2.0.1 fails to properly validate SSL/TLS server certificates, allowing an attacker positioned on the network path to intercept and decrypt traffic between the app and server. This is a classic improper certificate validation vulnerability where the app accepts invalid or malicious certificates, enabling Man-in-the-Middle attacks.

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 installed app versionOn the iOS device, go to Settings > General > Storage & iCloud Usage > Manage Storage, then find Call of Duty Elite and check the version number displayed. Alternatively, check the app's App Store listing history or the app's Info.plist if you have access to the binary.Affected if The installed version is exactly 2.0.1
-
Confirm network communicationUse a network proxy (such as Burp Suite or Charles Proxy) configured with an invalid or self-signed SSL certificate. Launch the Call of Duty Elite app and attempt to connect to its servers.Affected if The app successfully connects and communicates despite receiving an invalid certificate, indicating it does not properly validate certificates
-
Inspect certificate validation behaviorUse a Man-in-the-Middle proxy with a certificate that is signed by an untrusted CA. Capture the traffic between the app and server while observing whether the app accepts the proxy certificate.Affected if The app accepts connections through the MITM proxy without any certificate validation errors or warnings, confirming the improper validation vulnerability
-
Verify SSL/TLS handshakeCapture the SSL/TLS handshake using a network tracing tool. Observe whether the app verifies the server certificate chain, checks the certificate hostname, and validates against trusted root CAs.Affected if The app completes SSL/TLS connections without performing proper certificate chain validation or hostname verification
If the Call of Duty Elite iOS app version 2.0.1 is installed and accepts connections through a proxy with an invalid or untrusted certificate, the environment is affected by this improper certificate validation vulnerability.

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 proper SSL certificate chain validation in the iOS networking code, ideally with certificate pinning to bind the app to known-good server certificates. The app should reject connections when certificate validation fails.
