Cisco BroadWorks Improper Restriction of XML External Entity Reference Vulnerability
ما هي
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. An attacker could exploit this vulnerability by sending a crafted XML message to the Open Client Interface – Provisioning (OCI-P) service. A successful exploit could allow the attacker to view sensitive files from the filesystem with the privileges of the Cisco BroadWorks user.
CISA: Cisco BroadWorks contains an improper restriction of XML external entity reference vulnerability that could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system.
