Title

Opendaylight Vulnerable to Local and Remote File Inclusion in the Netconf (TCP) Service

Summary

Opendaylight (www.opendaylight.com) is vulnerable to Local and Remote File Inclusion in the Netconf (TCP) Service via an External Entity Injection (XXE). Opendaylight’s netconf service, when receiving an XML-RPC message, will process any external entities referenced in that message, local or remote. And will do so using its own running credentials which are root. So by injecting a reference to a local file, you can extract any file you like from the running system including the shadow file which can be leveraged by an attacker to perform an offline password attack.

Affected Products

Opendaylight 1.0 (Hydrogen) – Base, Virtualization, and Service Provider Editions

CVE

CVE-2014-5035

Details

“To Be Released Later”

Impact

Information Disclosure. Disclosure of hashed system credentials, which enables mounting of offline password attacks. Eventual disclosure of clear-text system credentials.
