A vulnerability has been reported to affect QNAP NAS. If exploited, this vulnerability allows an attacker to access sensitive information stored in cleartext inside cookies via certain widely-available tools. QNAP have already fixed this vulnerability in the following versions: QTS 4.5.1.1456 build 20201015 (and later) QuTS hero h4.5.1.1472 build 20201031 (and later) QuTScloud c4.5.2.1379 build 20200730 (and later)
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Qts | Qnap | * | 4.5.1.1456 (excluding) |
| Quts_hero | Qnap | * | h4.5.1.1472 (excluding) |
| Qutscloud | Qnap | * | c4.5.2.1379 (excluding) |
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.
