Vendor description
|
This security update resolves a privately reported vulnerability in the Open Data (OData) protocol. The vulnerability could allow denial of service if an unauthenticated attacker sends specially crafted HTTP requests to an affected site. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.

SophosLabs comments
|
TCP ports 80 and 443 are typically used for OData access. Blocking these ports at the firewall where feasible will mitigate exposure to this vulnerability.
Administrators could also enforce client authentication for access to IIS servers.
