Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-55147 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, affecting multiple Ivanti products. It impacts Ivanti Connect Secure versions before 22.7R2.9 or 22.8R2, Ivanti Policy Secure before 22.7R1.6, Ivanti ZTA Gateway before 2.8R2.3-723, and Ivanti Neurons for Secure Access before 22.8R1.4. The vulnerability has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.
A remote unauthenticated attacker can exploit this CSRF flaw by tricking an authenticated victim user into performing an unintended action, such as clicking a malicious link or visiting a crafted webpage. User interaction is required for successful exploitation. Upon success, the attacker can execute sensitive actions on behalf of the victim, potentially leading to unauthorized access, data modification, or other administrative privileges within the affected Ivanti gateways.
Ivanti's September Security Advisory details patches for this and related CVEs, recommending immediate upgrades to the fixed versions: Ivanti Connect Secure 22.7R2.9 or 22.8R2, Ivanti Policy Secure 22.7R1.6, Ivanti ZTA Gateway 2.8R2.3-723, and Ivanti Neurons for Secure Access 22.8R1.4 (with a fix deployed on 2025-08-02).

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require anti-CSRF controls such as tokens or SameSite attributes.

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.
Contextual intelligence about emerging CSRF toolkits can be translated into updated anti-CSRF token or same-site policy configurations across applications.
