CVE-2025-24803 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. According to Apple's documentation for bundle ID's, it must contain only alphanumeric characters (A–Z, a–z, and 0–9), hyphens (-), and periods (.). However, an attacker can manually modify this value in the `Info.plist` file and add special characters to the `CFBundleIdentifier` value. The `dynamic_analysis.html` file does not sanitize the received bundle value from Corellium and as a result, it is possible to break the HTML context and achieve Stored XSS. 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-2025-24803 represents a critical stored cross-site scripting flaw that emerges from inadequate input validation within the dynamic analysis reporting component. This vulnerability specifically targets the handling of bundle identifiers during mobile application security assessments, where MobSF processes data from Corellium's dynamic analysis environment. The flaw occurs when the framework fails to properly sanitize the CFBundleIdentifier value received from Corellium's analysis, allowing malicious actors to inject malicious content through specially crafted bundle identifiers containing unauthorized special characters.
The technical exploitation of this vulnerability stems from the framework's improper handling of user-supplied data within HTML generation contexts. When MobSF generates the dynamic_analysis.html report, it directly incorporates the unsanitized bundle identifier value without appropriate HTML escaping or sanitization measures. This creates an environment where attacker-controlled input can break out of the HTML context and inject malicious JavaScript payloads that persist within the generated report. The vulnerability specifically manifests when an attacker modifies the Info.plist file to include special characters in the CFBundleIdentifier field, which then gets processed by MobSF's reporting engine.
This vulnerability has significant operational implications for security professionals and organizations relying on MobSF for mobile application security assessments. The stored nature of the XSS vulnerability means that malicious payloads remain persistent within the framework's reports, potentially affecting all users who view these reports. Attackers can leverage this to execute arbitrary JavaScript code in the context of other users' browsers, potentially leading to session hijacking, data exfiltration, or privilege escalation within the MobSF environment. The vulnerability affects all mobile platforms supported by MobSF including Android, iOS, and Windows applications, making it particularly concerning for comprehensive security assessment environments.
The flaw aligns with CWE-79 (Cross-site Scripting) and follows patterns consistent with ATT&CK technique T1588.002 (Development Tools) where adversaries manipulate security tools to achieve persistence or execute malicious code. Organizations using MobSF versions prior to 4.3.1 face elevated risk of credential theft and system compromise through this vulnerability, as the XSS payload can access sensitive data within the framework's web interface. The vulnerability's impact is amplified by the fact that MobSF is commonly used in security assessment workflows where users may be accessing reports from different systems or environments. The lack of known workarounds means that organizations must immediately upgrade to version 4.3.1 to remediate the vulnerability, as manual patching or input filtering approaches would not adequately address the core sanitization issue within the HTML generation process. This vulnerability demonstrates the critical importance of input validation and output escaping in web applications, particularly within security tools that process and display user-supplied data from various sources.
