Description
A vulnerability in the Device Management Servlet application of Cisco BroadWorks Application Delivery Platform and Cisco BroadWorks Xtended Services Platform could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper input validation when parsing HTTP requests. An attacker could exploit this vulnerability by sending a sustained stream of crafted requests to an affected device. A successful exploit could allow the attacker to cause all subsequent requests to be dropped, resulting in a DoS condition.
Affected
Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.
22.0 ≤ v < 2022.11_1.273
Affected range stops below 2022.11_1.273, so it looks safe — our inference, not a vendor statement
22.0 ≤ v < 23.0.1075.ap384245
Affected range stops below 23.0.1075.ap384245, so it looks safe — our inference, not a vendor statement
