Huawei X6800 and XH620 V3 servers with software before V100R003C00SPC606, RH1288 V3 servers with software before V100R003C00SPC613, RH2288 V3 servers with software before V100R003C00SPC617, CH140 V3 and CH226 V3 servers with software before V100R001C00SPC122, CH220 V3 servers with software before V100R001C00SPC201, and CH121 V3 and CH222 V3 servers with software before V100R001C00SPC202 might allow remote attackers to decrypt encrypted data and consequently obtain sensitive information by leveraging selection of an insecure SSH encryption algorithm.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include:
Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include:
Information exposures can occur in different ways:
It is common practice to describe any loss of confidentiality as an “information exposure,” but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read. CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.
