Cisco BroadWorks Out-of-Band Blind XML External Entity Injection Vulnerability
Cisco patched an XXE flaw in BroadWorks' OCI XML parser letting unauthenticated remote attackers read sensitive files from the filesystem.
Cisco BroadWorks permits external entity resolution by default in its Open Client Interface XML parser, enabling out-of-band blind XXE injection. An unauthenticated remote attacker can send crafted XML to the OCI-P provisioning service and read sensitive configuration files with BroadWorks user privileges. Cisco has released software updates and no workarounds are available.
- XXE affects the OCI XML parser of Cisco BroadWorks
- No authentication is required for remote exploitation
- Successful exploitation exposes sensitive filesystem files and configuration data
- Software updates released; no workarounds available

From the original article
A vulnerability in the Open Client Interface (OCI) XML Parser of Cisco BroadWorks could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system. This vulnerability exists because XML entries are improperly parsed due to external entity resolution being allowed by default.
