CVE-2024-21633 Scanner

MobSF, also known as Mobile Security Framework, is widely used by developers and security professionals to analyze mobile application security. Integrated into development environments, MobSF provides static and dynamic analysis for both Android and iOS apps. It supports penetration testing efforts and helps in identifying security vulnerabilities before deploying applications. By enhancing app security, MobSF contributes to reducing risks associated with mobile apps in modern enterprises. Used globally, this tool assists in ensuring compliance with security policies. It plays a vital role in secure software development lifecycles.

Path Traversal vulnerabilities allow an attacker to manipulate file paths to access unauthorized files and directories outside the intended scope of the application. This type of vulnerability in MobSF can potentially lead to arbitrary file access and execution if exploited. Attackers may leverage Path Traversal to inject malicious files or overwrite existing ones, elevating their privileges within the system. Such vulnerabilities pose significant risks as they can bypass regular security controls. It's crucial to identify these vulnerabilities to prevent unauthorized access and potential data breaches. Security mechanisms need to be in place to detect and mitigate such threats effectively.

The Path Traversal vulnerability in MobSF allows attackers to exploit file paths used by apktool, a dependency within MobSF, to manipulate access levels and gain control over files and directories. Notably, the vulnerability arises due to improper validation of user-supplied inputs in file paths. The issue can lead to remote code execution or arbitrary file writing by exploiting crafted payloads within APK files. The attacker exploits vulnerable endpoints by submitting specially crafted requests. This could involve uploading malicious APK files containing payloads targeting specific file paths. Once exploited, the vulnerability could compromise the security of the underlying system.

An exploited Path Traversal vulnerability could have severe consequences, including unauthorized access to sensitive data, system modification, and loss of data integrity. Attackers could execute arbitrary code, potentially gaining administrative control over the MobSF application and related infrastructure. Sensitive application data might be exposed, leading to intellectual property theft or data leakage. The vulnerability could affect system availability if attackers delete or modify critical application files. Moreover, it opens avenues for further exploits within the compromised environment. Addressing this vulnerability is essential to prevent malicious activities and enhance system security.
