XXE in Eclipse Memory Analyzer report definition files

The Eclipse Foundation is a Common Vulnerabilities and Exposures (CVE) Numbering Authority. This issue it used to request and track the progress of the assignment of a CVE for a vulnerability in the project code for an Eclipse open source project.

Basic information

Project name: Eclipse Memory Analyzer

Project id: tools.mat

Request type: reservation

Versions affected: [0.7, 1.14.0]

Common Weakness Enumeration:

• CWE-611

Common Vulnerability Scoring System: 3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L/E:U/RL:W/RC:C/CR:X/IR:X/AR:X/MAV:L/MAC:L/MPR:L/MUI:R/MS:U/MC:L/MI:N/MA:L

Summary:

In Eclipse Memory Analyzer versions 0.7 to 1.14.0, report definition XML files are not filtered to prohibit document type definition (DTD) references to external entities. This means that if a user chooses to use a malicious report definition XML file containing an external entity reference to generate a report then Eclipse Memory Analyzer may access external files or URLs defined via a DTD in the report definition.

Workaround:

A workaround for Eclipse Memory Analyzer 1.14.0 and earlier is to run MAT with the following system properties set in MemoryAnalyzer.ini

-Djavax.xml.accessExternalSchema=
-Djavax.xml.accessExternalDTD=
