The vulnerability identified as CVE-2019-17397 represents a critical security flaw in the DoorDash mobile application for android platforms. This issue stems from improper handling of sensitive authentication data within the application's logging mechanisms. The vulnerability allows for the exposure of user credentials through log files that are accessible via the logcat functionality on android devices. The specific version affected includes all builds up to and including 11.5.2, indicating a widespread impact across multiple application releases.
The technical implementation of this vulnerability involves the application's logging subsystem where authentication credentials are inadvertently written to log files during the authentication process. When the application logs user credentials, including usernames and passwords, these sensitive details become accessible through standard android debugging tools. The logcat functionality provides a window into the application's runtime behavior and error messages, making it possible for attackers with access to the device to extract this information from the logs. This represents a fundamental failure in secure coding practices where sensitive data is not properly sanitized or filtered from logging output.
The operational impact of this vulnerability extends beyond simple credential theft, as it provides attackers with direct access to user authentication information without requiring complex exploitation techniques. Once an attacker gains access to the device or has the ability to read log files, they can immediately retrieve valid login credentials for DoorDash accounts. This creates a significant risk for user privacy and account security, as attackers can potentially access personal information, order history, payment details, and other sensitive data associated with compromised accounts. The vulnerability also enables persistent unauthorized access to user accounts, as stolen credentials can be used repeatedly without additional discovery efforts.
From a cybersecurity perspective, this vulnerability aligns with multiple common weakness enumerations including CWE-532, which describes information exposure through log files, and CWE-200, which addresses information exposure. The attack pattern follows typical privilege escalation techniques described in the attack tree methodology, where attackers can leverage device-level access to extract sensitive information from application logs. Organizations should consider implementing comprehensive logging policies that exclude sensitive data from standard log outputs and utilize secure credential storage mechanisms. The recommended mitigations include removing authentication data from log outputs, implementing proper log sanitization procedures, and conducting regular security audits of logging mechanisms to prevent similar vulnerabilities from occurring in future releases.
