TAIWAN SECOM CO., LTD., a Door Access Control and Personnel Attendance Management system, stores users’ information by cleartext in the cookie, which divulges password to attackers.

Weakness

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Affected Software

Name Vendor Start Version End Version
Dr.id_access_control Secom 3.3.2 (including) 3.3.2 (including)
Dr.id_attendance_system Secom * 3.3.0.3_20160517 (excluding)

Extended Description

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. 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. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
