{"id":"CVE-2025-24803","aliases":["GHSA-cxqq-w3x5-7ph3","PYSEC-2026-1673"],"url":"https://o3.security/vulnerability/CVE-2025-24803","summary":"Stored Cross-Site Scripting (XSS) in MobSF","details":"**Product:** MobSF\n**Version:** < 4.3.1\n**CWE-ID:** CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')\n**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)\n**CVSS vector v.3.1:** 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N)\n**Description:** Stored XSS in the iOS Dynamic Analyzer functionality.\n**Impact:** Leveraging this vulnerability would enable performing actions as users, including administrative users.\n**Vulnerable component:** `dynamic_analysis.html` \nhttps://github.com/MobSF/Mobile-Security-Framework-MobSF/blob/d1d3b7a9aeb1a8c8c7c229a3455b19ade9fa8fe0/mobsf/templates/dynamic_analysis/ios/dynamic_analysis.html#L406\n**Exploitation conditions:** A malicious application was uploaded to the Correlium.\n**Mitigation:** Use `escapeHtml()` function on the `bundle` variable.\n**Researcher: Oleg Surnin (Positive Technologies)**\n\n## Research\nResearcher discovered zero-day vulnerability Stored Cross-site Scripting (XSS) in MobSF in iOS Dynamic Analyzer functionality.\nAccording to Apple's documentation for bundle ID's, it must contain only alphanumeric characters (A–Z, a–z, and 0–9), hyphens (-), and periods (.).\n(https://developer.apple.com/documentation/bundleresources/information-property-list/cfbundleidentifier)\nHowever, an attacker can manually modify this value in `Info.plist` file and add special characters to the `<key>CFBundleIdentifier</key>` value.\nIn the `dynamic_analysis.html` file you do not sanitize received bundle value from Corellium \nhttps://github.com/MobSF/Mobile-Security-Framework-MobSF/blob/d1d3b7a9aeb1a8c8c7c229a3455b19ade9fa8fe0/mobsf/templates/dynamic_analysis/ios/dynamic_analysis.html#L406\n\n<img width=\"1581\" alt=\"image\" src=\"https://github.com/user-attachments/assets/8400f872-46c0-406c-9dd6-97655e499b75\" />\n\n*Figure 1. Unsanitized bundle*\n\nAs a result, it is possible to break the HTML context and achieve Stored XSS.\n\n## Vulnerability reproduction\n\nTo reproduce the vulnerability, follow the steps described below.\n\n•\tUnzip the IPA file of any iOS application.\n*Listing 1. Unzipping the file*\n```\nunzip test.ipa\n```\n•\tModify the value of `<key>CFBundleIdentifier</key>` by adding restricted characters in the `Info.plist` file.\n\n<img width=\"560\" alt=\"image-1\" src=\"https://github.com/user-attachments/assets/3eedf216-45ab-4d73-9815-6b02827d36d4\" />\n\n*Figure 2. Example of the modified Bundle Identifier*\n\n•\tZip the modified IPA file.\n\n*Listing 2. Zipping the file*\n```\nzip -r xss.ipa Payload/\n```\n•\tUpload the modified IPA file to your virtual device using the Correlium platform.\n \n<img width=\"762\" alt=\"image-2\" src=\"https://github.com/user-attachments/assets/7f3e8b0d-d1f9-4d86-b63b-9b3f9e8f1d0c\" />\n\n*Figure 3. Example of the uploaded malicious application*\n\n•\tOpen the XSS functionality and hover the mouse over the Uninstall button of the malicious app.\n\n<img width=\"764\" alt=\"image-3\" src=\"https://github.com/user-attachments/assets/fd621574-f2c1-42be-b30a-e8e7445c6b13\" />\n\n*Figure 4.
