Impact
xml files like ".project" are parsed vulnerable against all sorts of XXE attacks. The user just needs to open any evil project or update an open project with a vulnerable file (for example for review a foreign repository or patch).
Vulnerablility was found by static code analysis (SonarLint).
Example .project file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE price [
<!ENTITY xxe SYSTEM "http://127.0.0.1:49416/evil">]>
<projectDescription>
<name>p</name>
<comment>&xxe;</comment>
</projectDescription>
Patches
Similar patches including junit test that shows the vulnerability have already applied to PDE (see eclipse-pde/eclipse.pde#667). A solution to platform should be the same: just reject parsing any XML that contains any DOCTYPE.
Workarounds
No known workaround. User can only avoid to get/open any foreign files with eclipse. Firewall rules against loss of data (but not against XML bomb).
