名称

Cleartext Transmission of Sensitive Information

描述

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

常见后果

范围:
Integrity, Confidentiality
影响:
Read Application Data, Modify Files or Directories
注释:
Anyone can read the information by gaining access to the channel being used for communication. Many communication channels can be "sniffed" (monitored) by adversaries during data transmission. For example, in networking, packets can traverse many intermediary nodes from the source to the destination, whether across the internet, an internal network, the cloud, etc. Some actors might have privileged access to a network interface or any link along the channel, such as a router, but they might not be authorized to collect the underlying data. As a result, network traffic could be sniffed by adversaries, spilling security-critical data.
范围:
Integrity, Confidentiality
影响:
Read Application Data, Modify Files or Directories, Other
注释:
When full communications are recorded or logged, such as with a packet dump, an adversary could attempt to obtain the dump long after the transmission has occurred and try to "sniff" the cleartext from the recorded communications in the dump itself. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.
