CVE-2018-1000123
📋 TL;DR
This vulnerability in the Ionic Team Cordova iOS Keychain plugin exposes sensitive data like login credentials and passwords through iOS log files. Attackers who gain access to a victim's iOS logs can extract this information. This affects iOS applications using vulnerable versions of the cordova-plugin-ios-keychain plugin.
💻 Affected Systems
- cordova-plugin-ios-keychain
📦 What is this software?
Ios Keychain by Ionicframework
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of user credentials, passwords, and other sensitive data stored via the keychain plugin, potentially leading to account takeover and data breaches.
Likely Case
Exposure of sensitive authentication data to attackers with access to device logs, enabling credential theft and unauthorized access.
If Mitigated
Limited impact if logs are properly secured and access-controlled, though sensitive data remains exposed in log files.
🎯 Exploit Status
Exploitation requires access to iOS device logs, which typically requires physical access, malware, or compromised device management tools.
🛠️ Fix & Mitigation

Patch Version: Commit 18233ca25dfa92cca018b9c0935f43f78fd77fbf and later
Vendor Advisory: https://github.com/ionic-team/cordova-plugin-ios-keychain/pull/29/commits/980230645c8ea3b531b85401de5e4bca0f860e42#diff-936020291e4c2115faff0171f20672a4
Restart Required: Yes
Instructions:
1. Update cordova-plugin-ios-keychain to version containing commit 18233ca25dfa92cca018b9c0935f43f78fd77fbf or later. 2. Rebuild and redeploy the iOS application. 3. Restart the application on all affected devices.
🔧 Temporary Workarounds
Disable debug logging
allConfigure the application to disable debug logging that may expose sensitive information.
Modify iOS application configuration to set appropriate logging levels (e.g., in Xcode or build settings).
Secure log storage
iosImplement controls to restrict access to iOS device logs.
Use iOS security features like encrypted logging and access controls to protect log files.
🧯 If You Can't Patch
- Implement strict access controls to device logs and monitor for unauthorized access.
- Audit and sanitize logs regularly to remove any exposed sensitive data.
🔍 How to Verify
Check if Vulnerable:
Check the cordova-plugin-ios-keychain plugin version in your project's package.json or plugin.xml. Verify if the commit hash is before 18233ca25dfa92cca018b9c0935f43f78fd77fbf.
Check Version:
cordova plugin list | grep cordova-plugin-ios-keychain
Verify Fix Applied:
Confirm the plugin version includes commit 18233ca25dfa92cca018b9c0935f43f78fd77fbf or later, and test that sensitive data is no longer logged in iOS debug logs.
📡 Detection & Monitoring
Log Indicators:
- Sensitive data like passwords or login credentials appearing in iOS system or application logs.
Network Indicators:
- Unusual log access patterns or unauthorized attempts to retrieve device logs.
SIEM Query:
Example: Search for log entries containing keychain-related data or sensitive strings in iOS log sources.
