This vulnerability in Cisco BroadWorks' OCI XML Parser permits an unauthenticated remote attacker to send specially crafted XML messages to the OCI-P service. Due to improper restriction of XML external entity references, the attacker can cause the parser to resolve external entities and read sensitive files from the system. The flaw stems from external entity resolution being allowed by default, leading to exposure of sensitive configuration information with the privileges of the Cisco BroadWorks user.

An attacker exploiting this vulnerability can read sensitive files on the affected system without authentication, potentially exposing confidential configuration data. The impact is confidentiality loss only, with no integrity or availability impact reported. The attacker gains access with the privileges of the Cisco BroadWorks user, which may be significant depending on deployment.

Patch status is not yet confirmed — check the Cisco vendor advisory for current remediation guidance. No official fix or workaround information is provided in the available data. Until a patch is available, restrict network access to the OCI-P service to trusted sources to reduce exposure.
