Description

The JavaScriptUtils.javaScriptEscape() method did not escape all characters that are sensitive within either a JS single quoted string, JS double quoted string, or HTML script data context. In most cases this will result in an unexploitable parse error but in some cases it could result in an XSS vulnerability.

Affected Spring Products and Versions

• Spring MVC 3.0.0 to 3.2.1
• Earlier unsupported versions may be affected

Mitigation

Users of affected versions should apply the following mitigation:

• Users of 3.x should upgrade to 3.2.2 or later

Description

The Spring OXM wrapper did not expose any property for disabling entity resolution when using the JAXB unmarshaller. There are four possible source implementations passed to the unmarshaller: DOMSource, StAXSource, SAXSource and StreamSource.

For a DOMSource, the XML has already been parsed by user code and that code is responsible for protecting against XXE.

For a StAXSource, the XMLStreamReader has already been created by user code and that code is responsible for protecting against XXE.

For SAXSource and StreamSource instances, Spring processed external entities by default thereby creating this vulnerability.

The issue was resolved by disabling external entity processing by default and adding an option to enable it for those users that need to use this feature when processing XML from a trusted source.

Affected Spring Products and Versions

• 3.0.0 to 3.2.3
• 4.0.0.M1
• Earlier unsupported versions may be affected

Mitigation

Users of affected versions should apply the following mitigation:

• Users of 3.x should upgrade to 3.2.4 or later
• Users of 4.x should upgrade to 4.0.0.M2 or later

Description

It was identified that Spring MVC processed user provided XML with JAXB in combination with a StAX XMLInputFactory without disabling external entity resolution. External entity resolution has been disabled in this case. It was subsequently discovered that this fix was incomplete (CVE-2013-6429, CVE-2014-0054).

Affected Spring Products and Versions

• 3.2.0 to 3.2.3
• 4.0.0.M1-4.0.0.M2 (Spring MVC)
• Earlier unsupported versions may be affected

Mitigation

Users of affected versions should apply the following mitigation:

• Users of 3.x should upgrade to 3.2.4 or later
• Users of 4.x should upgrade to 4.0.0.RC1 or later
• To fully mitigate this issue (including CVE-2013-6429 & CVE-2014-0054), users of 3.x should upgrade to 3.2.8 or later and users of 4.x should upgrade to 4.0.2 or later.
