CVE-2025-24805 in Mobile-Security-Framework-MobSF
Summary
by MITRE • 02/05/2025
Mobile Security Framework (MobSF) is an automated, all-in-one mobile application (Android/iOS/Windows) pen-testing, malware analysis and security assessment framework. A local user with minimal privileges is able to make use of an access token for materials for scopes which it should not be accepted. This issue has been addressed in version 4.3.1 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

The Mobile Security Framework (MobSF) vulnerability CVE-2025-24805 represents a critical access control flaw that undermines the security posture of this widely-used mobile application security assessment tool. This vulnerability affects MobSF versions prior to 4.3.1 and exposes a significant privilege escalation risk through improper token validation mechanisms. The flaw allows local users with minimal privileges to exploit access tokens that should be restricted to specific scopes, effectively granting them unauthorized access to resources and functionality beyond their intended permissions. This issue specifically targets the authentication and authorization subsystem of the framework, where token validation fails to properly verify the scope and permissions associated with each access token. The vulnerability demonstrates a clear breakdown in the principle of least privilege, which is a fundamental security principle outlined in the CWE taxonomy under CWE-284 for improper access control. Organizations relying on MobSF for mobile application security testing and penetration testing face substantial risk exposure, as this flaw could enable malicious actors with low-privilege access to escalate their privileges and gain unauthorized access to sensitive security assessment data, test results, and potentially compromise the integrity of the entire security testing environment.
The technical implementation of this vulnerability stems from inadequate token scope validation within MobSF's authentication system, creating an opportunity for privilege escalation through token manipulation. When local users interact with the framework's API or administrative interfaces, the system fails to properly validate whether the provided access tokens are authorized for the specific operations being requested. This flaw likely occurs in the authorization middleware layer where tokens are processed and validated against expected scopes, allowing tokens to be accepted for operations outside their designated permissions. The vulnerability manifests as a failure to enforce proper access control boundaries, enabling unauthorized access to administrative functions and sensitive data within the framework. Security assessments conducted through MobSF may be compromised, as attackers could potentially access confidential test results, modify security configurations, or manipulate the framework's operational parameters. The lack of a known workaround forces organizations to immediately upgrade to version 4.3.1, as no temporary mitigations can be implemented without potentially compromising the framework's functionality or security posture.
Organizations utilizing MobSF for mobile application security assessments must prioritize immediate remediation of this vulnerability to prevent potential exploitation and maintain the integrity of their security testing operations. The vulnerability's impact extends beyond simple unauthorized access, as it could enable attackers to manipulate security testing results, compromise sensitive data within the framework, or potentially use the compromised system as a staging ground for further attacks against target applications. The security implications are particularly concerning given that MobSF is designed for penetration testing and security assessment activities, making it a valuable target for threat actors seeking to undermine security testing processes. This vulnerability aligns with ATT&CK technique T1548.001 for abuse of system permissions, where adversaries leverage legitimate system access to gain elevated privileges. Organizations should implement comprehensive monitoring of MobSF access logs and authentication events to detect potential exploitation attempts. The remediation process requires careful attention to ensure that the upgrade to version 4.3.1 does not introduce compatibility issues with existing security testing workflows, while also verifying that all access tokens and authentication mechanisms are properly reconfigured to enforce the correct scope limitations. Security teams should also conduct thorough access reviews to ensure that no unauthorized access has occurred during the vulnerability's active period, particularly focusing on administrative access patterns and token usage within the framework's operational environment.
