Each year, OWASP identifies the ten most critical security risks faced by the cyber world.
It serves as a roadmap for developers to prioritize vulnerabilities and strengthen their code, and for security professionals to assess the potential risks lurking within the applications.
In this blog, we embark on the 2024 OWASP top 10 vulnerabilities for mobile application considering a complete journey, delving into each security challenge to unravel its intricacies.
The specter of threat agents exploiting hardcoded credentials and mishandling user credentials looms large these days.
These actors come armed with automated tools, be they publicly accessible or crafted for specific exploits- they scan and exploit hardcoded credentials or capitalize on vulnerabilities arising from improper credential usage.
When improper handling of user credentials comes under the scrutiny of a potential attacker, a gateway to unauthorized access to sensitive functionalities within the mobile app swings open.
An attacker can exploit these predetermined access keys to infiltrate and navigate through the mobile application. This unauthorized access grants them entry into functionalities that are meant to be safeguarded.
Unauthorized Access to Sensitive Information and poor credential management opens the door for unauthorized users to gain access to sensitive information stored within the mobile app.
Data breaches and loss of privacy entrust mobile applications with one’s personal information. The fraudulent activities and adversaries equipped with improperly managed credentials can also engage in fraudulent activities within the mobile app.
First, eliminate the use of hardcoded credentials in your mobile application. These easily discoverable access keys create a vulnerable entry point for attackers.
Prioritize the secure management of user credentials throughout their lifecycle which includes encrypting credentials, avoid storing user credentials, implementing user authentication protocols etc.
Inadequate supply chain security stands out as a critical concern. Exploiting vulnerabilities in the mobile app supply chain enables attackers to manipulate application functionality, posing a significant threat to the overall security of the system.
For example: Inadequate supply chain security in a mobile application could be an attacker compromising a third-party library used in the app. If the library is not regularly updated, and the developer fails to incorporate the latest security patches, it creates a vulnerability.
Inadequate supply chain security is exploited through various methods, often taking advantage of vulnerabilities introduced in the supply chain processes.
A threat actor has the potential to capitalize on vulnerabilities present in third-party libraries or components utilized within the application.
The impacts of inadequate supply chain security can be far-reaching and have serious consequences for an organization. It can lead to the compromise of software integrity, unauthorized access to sensitive data, leading to data breaches.
Disruptions in operations, affecting the availability and functionality of software or hardware products along with the compromise of the entire supply chain ecosystem.
Vendor assessment: Conduct thorough assessments of vendors and third-party suppliers before engaging in partnerships.
Secure development Practices: Implement secure coding practices and conduct regular security reviews during the development phase.
Employ encrypted communication channels throughout the supply chain to protect data during transit and implement continuous monitoring mechanisms to detect and respond to security incidents promptly.
Malicious actors exploiting authentication and authorization vulnerabilities commonly employ automated attacks, utilizing either readily available or custom-crafted tools.
This includes issues like weak authentication, flawed authorization controls, insecure session management, and inadequate credential storage. Addressing these concerns is crucial for ensuring robust mobile app security.
When a threat is identified vulnerabilities in either the authentication or authorization framework, they can exploit these weaknesses in two distinct manners.
They might falsify or bypass authentication by directly submitting service requests to the backend server of the mobile app, avoiding any direct engagement with the app.
They can even log into the application as a legitimate user after passing authentication controls and then navigate to a vulnerable endpoint to execute administrative functionality.
Unauthorized access: Attackers can gain unauthorized access to sensitive data, user accounts, or restricted functionalities within the mobile app.
Identity theft: Exploiting authentication vulnerabilities can enable identity theft, allowing attackers to impersonate legitimate users.
Financial loss: Insecure authentication may lead to unauthorized financial transactions or fraudulent activities, resulting in financial losses for both users and the app provider.
Ensure that the authentication requirements for mobile applications align with those of the web application component.
On jailbroken devices, the authentication routine of the application can be circumvented through runtime manipulation or binary modification if the app stores data locally.
Backend systems must autonomously validate the roles and permissions assigned to authenticated users. Do not depend on role or permission data originating from the mobile device.
Inadequate validation and sanitization of data sourced externally, like user inputs or network data, pose significant security threats to mobile applications.
Apps lacking proper validation and sanitization measures become susceptible to exploitation through mobile-specific attacks, including SQL injection, Command Injection, and cross-site scripting (XSS) attacks.
Inadequate input/output validation opens our application to severe attack vectors, such as SQL injection, XSS, command injection, and path traversal. These vulnerabilities may result in unauthorized access, data manipulation, code execution, and compromise of the entire backend system.
This vulnerability can be exploited by attackers to execute unauthorized code, potentially resulting in system compromise and unauthorized access. Insufficient validation enables attackers to manipulate input, leading to data breaches and unauthorized access to sensitive information.
implement strict validation rules: Enforce rigorous input validation rules to ensure that data from external sources.
Use whitelisting: Employ whitelisting techniques to allow only approved characters and patterns, rejecting any input that doesn’t conform to the established criteria.
Sanitize user inputs: Implement thorough data sanitization for user inputs to remove any malicious content or characters that could lead to vulnerabilities like XSS attacks.
Avoid trusting client-side data: Do not solely rely on data validation performed on the client side, as it can be manipulated.
Many contemporary mobile applications interact with remote servers for data exchange. During data transmission, which often traverses the mobile device’s carrier network and the internet, there is a risk of interception and modification by a threat agent if the data is transmitted without encryption or relies on outdated encryption protocols.
This insecurity in communication can expose sensitive information to potential threats. Common issues include the lack of encryption, weak encryption protocols, or improper implementation of secure communication channels.
Attackers may use packet sniffing tools to intercept and analyze data packets traveling over the network. If the communication is not encrypted, the attacker can easily read the sensitive information.
In a MitM attack, an attacker positions themselves between the mobile device and the server, intercepting and possibly modifying the communication.
Utilizing outdated protocols or improperly configured settings, such as accepting basic SSL certificates.
The immediate impacts of insecure communication include identity theft, fraudulent activities and reputational damage.
Data breaches: Insecure communication channels can lead to unauthorized access to sensitive data, resulting in data breaches.
Compromised privacy: Insecure communication can violate individuals’ privacy by exposing personal or confidential information.

Implement HTTPS: Ensure that all communication between the mobile app and servers occurs over HTTPS. This guarantee encrypted and secure data transmission.
Certificate validation: Implement rigorous validation checks for SSL/TLS certificates. Reject self-signed, expired, revoked, or incorrectly configured certificates to thwart potential attacks.
Secure configuration: Configure servers and communication settings securely. Follow best practices for cipher suites, key lengths, and other parameters to enhance overall security.
This could involve insufficient safeguards for sensitive user data, inadequate consent mechanisms, or weak controls over the collection, storage, or sharing of personal information.
This vulnerability exposes users to potential privacy breaches, unauthorized access to personal data, or misuse of sensitive information.
Common sources of Personally Identifiable Information (PII) within mobile applications, such as the app’s sandbox, network communication, logs, and backups, are typically well-protected.
Some sources, like URL query parameters and clipboard content, have less stringent protection but are still challenging to access.
For an attacker to obtain PII, they would need to breach security at another level. This could involve eavesdropping on network communication, accessing the file system, clipboard, or logs using a trojan, or physically obtaining the mobile device to create a backup for analysis. PII, being data that can be stored, processed, and transmitted through various means on mobile devices, presents diverse opportunities for extraction or manipulation.
Unauthorized access: Weak privacy controls may result in unauthorized access to sensitive user data
Data misuse: Inadequate privacy measures increase the risk of data misuse, where personal information may be exploited for malicious purposes
