Vulnerability Data

NETGEAR RAX30 Device Configuration Cleartext Storage Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR RAX30 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.…

more

The specific flaw exists within the handling of device configuration. The issue results from the storage of configuration secrets in plaintext. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-19841.

Mitigating Controls (NIST 800-53 r5) AI

SC-28 Protection of Information at Rest good match

SC-28 requires cryptographic or equivalent protection of sensitive data at rest, directly stopping cleartext storage in accessible resources.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

A.7.14 Secure disposal or re-use of equipment partial match
mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

A.7.9 Security of assets off-premises partial match
mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

A.8.10 Information deletion partial match
mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.

A.8.12 Data leakage prevention partial match
finds

When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.

A.8.33 Test information partial match
mitigates

By insisting that any retained test copies be stored securely and only for testing, the control reduces the likelihood that clear-text operational data will persist on disk or in backups.
