Summary

CVE-2021-35486 is a high-severity CSRF (CWE-352) vulnerability in Nokia Impact Mobile. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2021-35486 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, affecting Nokia IMPACT through version 19.11.2.10-20210118042150283. The flaw exists in the /ui/rest-proxy/entity/import endpoint, where neither the X-CSRF-NONCE HTTP header nor the CSRF-NONCE cookie is validated, enabling a remote attacker to import and overwrite the entire application configuration.

A remote attacker with no required privileges (PR:N) can exploit this vulnerability by tricking an authenticated user (UI:R) into interacting with a malicious webpage, such as via a crafted link. Successful exploitation allows the attacker to fully overwrite the application's configuration, resulting in high confidentiality and integrity impacts (C:H/I:H) with no availability impact (A:N), as reflected in the CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N).

Mitigating Controls (NIST 800-53 r5) AI

Access enforcement requires verifying that state-changing requests originate from the authenticated user rather than a forged cross-site source.

Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.

By denying access to phishing or malicious sites, the control lowers the likelihood that a user will be tricked into submitting a forged request that performs an unintended action on another site.
