Version: < 4.3.1
CWE-ID: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSS vector v.4.0: 8.5 (AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N)
CVSS vector v.3.1: 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N)
Description: Stored XSS in the iOS Dynamic Analyzer functionality.
Impact: Leveraging this vulnerability would enable performing actions as users, including administrative users.
Vulnerable component: dynamic_analysis.html
https://github.com/MobSF/Mobile-Security-Framework-MobSF/blob/d1d3b7a9aeb1a8c8c7c229a3455b19ade9fa8fe0/mobsf/templates/dynamic_analysis/ios/dynamic_analysis.html#L406
Exploitation conditions: A malicious application was uploaded to the Correlium.
Mitigation: Use escapeHtml() function on the bundle variable.
Researcher: Oleg Surnin (Positive Technologies)
Research
Researcher discovered zero-day vulnerability Stored Cross-site Scripting (XSS) in MobSF in iOS Dynamic Analyzer functionality.
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 (.).
(https://developer.apple.com/documentation/bundleresources/information-property-list/cfbundleidentifier)
However, an attacker can manually modify this value in Info.plist file and add special characters to the <key>CFBundleIdentifier</key> value.
In the dynamic_analysis.html file you do not sanitize received bundle value from Corellium

Figure 1. Unsanitized bundle
As a result, it is possible to break the HTML context and achieve Stored XSS.
Vulnerability reproduction
To reproduce the vulnerability, follow the steps described below.
• Unzip the IPA file of any iOS application. Listing 1. Unzipping the file
unzip test.ipa
• Modify the value of <key>CFBundleIdentifier</key> by adding restricted characters in the Info.plist file.
Figure 2. Example of the modified Bundle Identifier
• Zip the modified IPA file.
Listing 2. Zipping the file
zip -r xss.ipa Payload/
• Upload the modified IPA file to your virtual device using the Correlium platform.
Figure 3. Example of the uploaded malicious application
• Open the XSS functionality and hover the mouse over the Uninstall button of the malicious app.
Figure 4. Example of the 'Uninstall' button
