Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-5797C807-4279-11EA-B184-F8B156AC3FF9:

Problem Description:

A missing check means that an attacker can reinject an old packet and

it will be accepted and processed by the IPsec endpoint.

Impact:

The impact depends on the higher-level protocols in use over IPsec.

For example, an attacker who can capture and inject packets could

cause an action that was intentionally performed once to be repeated.
