CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HSummary
CVE-2024-45538 is a critical-severity CSRF (CWE-352) vulnerability in Synology Diskstation Manager. Its CVSS base score is 9.6 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 29th 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-45538 is a Cross-Site Request Forgery (CSRF) vulnerability, mapped to CWE-352, in the WebAPI Framework of Synology DiskStation Manager (DSM) versions before 7.2.1-69057-2 and 7.2.2-72806, and Synology Unified Controller (DSMUC) versions before 3.1.4-23079. Published on 2025-12-04, it carries a CVSS v3.1 base score of 9.6 (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H). The issue enables remote attackers to execute arbitrary code through unspecified vectors.
Remote unauthenticated attackers can exploit this vulnerability by crafting malicious web pages or links that induce authenticated users to perform unintended actions on affected Synology devices. Exploitation requires user interaction, such as visiting a malicious site, but needs no privileges from the attacker. Successful attacks result in arbitrary code execution with high confidentiality, integrity, and availability impacts, potentially compromising the entire system due to the changed scope.
Synology's security advisory Synology_SA_24_27, available at https://www.synology.com/en-global/security/advisory/Synology_SA_24_27, details mitigation through updates to DSM 7.2.1-69057-2, DSM 7.2.2-72806, or DSMUC 3.1.4-23079 and later. Security practitioners should prioritize patching affected systems and advise users to avoid untrusted links.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
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.
