Published: 04 April 2022
Summary
CVE-2022-1026 is a high-severity Insufficiently Protected Credentials (CWE-522) vulnerability in Kyocera Net Viewer. Its CVSS base score is 8.6 (High).
Operationally, ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Kyocera multifunction printers running vulnerable versions of Net View expose sensitive user information, including usernames and passwords, through an insufficiently protected address book export function. The flaw is tracked as CVE-2022-1026 with a CVSS 3.1 score of 8.6 and is associated with CWE-522 for insufficiently protected credentials.
Remote attackers without authentication can retrieve the exposed address book contents over the network, resulting in high confidentiality impact that extends beyond the immediate device scope. The attack requires no user interaction and can be carried out against any reachable vulnerable printer.
Vendor advisories published by Kyocera and technical analysis from Rapid7 at the referenced URLs describe the issue and direct administrators to apply available updates or configuration changes to restrict access to the address book export functionality. The EPSS score reached a peak of 0.9001 with a current value of 0.8584.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Training instructs users on protecting credentials from disclosure or unauthorized access.
Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.
Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.
Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.
Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.
Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.
Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.
