Official description
A vulnerability has been identified in Omnivise T3000 Application Server R9.2 (All versions), Omnivise T3000 Domain Controller R9.2 (All versions), Omnivise T3000 Network Intrusion Detection System (NIDS) R9.2 (All versions), Omnivise T3000 Product Data Management (PDM) R9.2 (All versions), Omnivise T3000 R8.2 SP3 (All versions), Omnivise T3000 R8.2 SP4 (All versions), Omnivise T3000 Security Server R9.2 (All versions), Omnivise T3000 Terminal Server R9.2 (All versions), Omnivise T3000 Thin Client R9.2 (All versions), Omnivise T3000 Whitelisting Server R9.2 (All versions). The affected devices stores initial system credentials without sufficient protection. An attacker with remote shell access or physical access could retrieve the credentials leading to confidentiality loss allowing the attacker to laterally move within the affected network.

The underlying weakness: Cleartext Storage of Sensitive Information
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
How developers prevent this class of flaw
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
- 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.
