Detailsinfo

A vulnerability has been found in Belkin WeMo 2769 and classified as problematic. Affected by this vulnerability is an unknown code block of the component XML Handler. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality. The summary by CVE is:

The peerAddresses API in the Belkin WeMo Home Automation firmware before 3949 allows remote attackers to read arbitrary files via an XML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

The weakness was released 02/18/2014 by Mike Davis with IOActive as VU#656302 as confirmed vulnerability note (CERT.org). It is possible to read the advisory at kb.cert.org.
