EXPLOIT

Internet Explorer 4.0 and later allows remote attackers to read arbitrary files via a web page that accesses a legacy XML Datasource applet (com.ms.xml.dso.XMLDSO.class) and modifies the base URL to point to the local system, which is trusted by the applet.

other com.ms.xml.dso.XMLDSO.class↗

command xmldso.getDocument()↗

• → Look for web pages that instantiate the com.ms.xml.dso.XMLDSO.class applet with a codebase pointing to the local system (e.g., codebase="file:///" or codebase pointing to local paths), indicating an attempt to abuse trusted local context for file disclosure. ↗
• → Monitor for JavaScript calls to xmldso.getDocument() on pages loaded from remote origins, which is the mechanism used to extract local file contents via the XML Datasource applet. ↗

• · The vulnerability affects Internet Explorer 4.0 and later; the XML Datasource applet (com.ms.xml.dso.XMLDSO.class) must be present and enabled in the browser for exploitation to succeed. ↗
• · Exploitation relies on the applet trusting the local system when the codebase is redirected; the attacker must know the path of the target file in advance. ↗
