M8: Security Misconfiguration (2023): (Rewording M10(2016))
Involves incorrect configuration settings within mobile applications, exposing them to potential security vulnerabilities.
This may lead to unauthorized access, data exposure, or exploitation of misconfigured settings by attackers.
The OWASP top ten mobile’s first risk, “Improper Credential Usage,” underscores the critical issue of mishandling credentials within mobile applications.
One specific manifestation of this risk is the prevalence of hardcoded credentials in application binaries, a common but dangerous practice. Hardcoded credentials pose a significant security risk as they can be easily exposed, leading to unauthorized access and potential harm to the business.
Attackers can leverage vulnerabilities associated with both hardcoded credentials and improper credential usage.
Once these vulnerabilities are identified, attackers can exploit hardcoded credentials to infiltrate the application, potentially gaining access to sensitive data and functionalities.
Additionally, they may misuse credentials by exploiting improperly validated or stored credentials, bypassing legitimate access controls.
Mobile Application Vulnerabilities to Look For:
Prevention and Mitigation Strategies:
The supply chain encompasses the entire process from collecting materials, such as software libraries and SDKs, through the development phase to the final distribution via mobile app stores. Failures in securing this supply chain can introduce vulnerabilities that adversaries may exploit.
For example, an attacker could put malicious code in a mobile app or change it while building it. This could let them steal info, spy on users, or control the mobile device. They might also find weaknesses in other software parts to get into the app or servers, causing problems like unauthorized access or completely taking over the app or device.
Prevention and Mitigation Strategies
Unlike traditional web apps, mobile devices’ unique input form factor often leads to weaker authentication practices, such as using shorter passwords like 4-digit PINs.
Additionally, the irregular and less predictable nature of mobile internet connections requires thoughtful consideration for offline authentication, introducing complexities for developers.
In addition to authentication challenges, improper authorization practices can amplify risks in mobile app security.
Improper authorization may result in users accessing functionalities or data beyond their intended scope, potentially leading to data breaches or misuse.
Exploiting these security risks in mobile apps can occur through two distinct methods:
1. Authentication Manipulation:
Attackers can manipulate authentication by forging or bypassing it, submitting service requests directly to the app’s backend without engaging with the app directly.
2. User Impersonation and Administrative Actions:
Another tactic involves attackers logging in as legitimate users and navigating to specific mobile application threats. This enables them to execute administrative functionalities stealthily.
Protection and Mitigation Strategies:
The process of validating inputs is a common practice to examine potentially harmful data, ensuring its safety for processing within the code or when interfacing with other components.
When software fails to perform proper input validation, it opens the door for attackers to manipulate inputs in unexpected ways. Consequently, various system parts may receive unintended input, potentially leading to SQL injection, Command Injection, and cross-site scripting (XSS) attacks.
In scenarios involving sensitive information, insufficient output validation can lead to the inadvertent exposure of confidential data. For instance, if a system fails to properly validate and sanitize output in log files or error messages, it may unintentionally disclose sensitive information.
These security lapses can lead to unauthorized access data manipulation and compromise the overall integrity of the mobile app.
Protection and Mitigation Strategies
Insecure communication in a mobile app refers to transmitting sensitive information (such as login credentials, personal data, or financial details) over unsecured channels, making it susceptible to interception and unauthorized access.
It is crucial for app developers to implement secure communication practices to protect user data and maintain the integrity of the application.
Risks and Impacts
Protection and Mitigation Strategies
Inadequate privacy controls in mobile apps pose significant risks to user data, potentially compromising sensitive information and eroding user trust. This risk arises when developers fail to implement robust measures to protect user data privacy, leading to various privacy violations.
Issues include collecting more than needed, sharing data without user consent, and careless handling of Personally Identifiable Information (PII). This exposes users to privacy violations, potential identity theft, and legal consequences.
Prevention and Mitigation Strategies
The binary code is a critical component of the app’s functionality, and its security is paramount for protecting user data and ensuring the app operates as intended.
However, attackers often target the binary code due to its vulnerability, seeking to exploit weaknesses for malicious purposes.
Attackers take advantage of this weakness by doing things like figuring out how the app works (reverse engineering), changing its code (tampering), or analyzing it while it’s running (dynamic analysis). This can lead to serious problems, such as stealing sensitive data or creating malicious app versions.
Prevention and Mitigation Strategies:
Security misconfiguration refers to situations where crucial security settings are either not implemented, implemented with errors, or deployed with default (potentially insecure) settings. This vulnerability can introduce weaknesses that make the mobile app susceptible to cyberattacks or data breaches.
For instance, mobile apps often come with default settings for ease of use, but these defaults may not prioritize security. If developers fail to customize and secure these default settings, the app can be left exposed.
Prevention and Mitigation Strategies:
Insecure data storage in mobile apps is like keeping your personal secrets in a place that’s not well-protected. Imagine if your important passwords or private information were stored on your phone without being properly guarded. This is a problem because two things can happen:
Prevention and Mitigation Strategies
Insufficient cryptography refers to using encryption methods that can be easily compromised. This vulnerability can arise from flaws in the encryption process or the adoption of weak encryption algorithms to safeguard sensitive data.
It’s essential for mobile developers to grasp that the objective of cryptography is not to create unbreakable codes but rather to make breaking them impractical within a reasonable timeframe, given the current state of computational power.
Prevention and Mitigation Strategies:
Incorporating mobile application scanning is the first crucial step in defending your apps against potential threats. This process protects your business applications from the vulnerabilities outlined in the OWASP mobile top 10 list.
Additionally, engaging pen testers to simulate hacker techniques and uncover potential vulnerabilities is essential. Their manual approach is instrumental in identifying business logic risks that automated tools might overlook.
