CVE-2023-22472: Nextcloud Deck Desktop Client is vulnerable to Cross-Site Request Forgery (CSRF) via malicious link

Noroxi assessment

Priority: Monitor (action score 35/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: nextcloud-client (Alpine:v3.18) 3.6.2-r0.
Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 8.8.

Low priority for now. Upgrade to nextcloud-client (Alpine:v3.18) 3.6.2-r0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Deck is a kanban style organization tool aimed at personal planning and project organization for teams integrated with Nextcloud. It is possible to make a user send any POST request with an arbitrary body given they click on a malicious deep link on a Windows computer. (e.g. in an email, chat link, etc). There are currently no known workarounds. It is recommended that the Nextcloud Desktop client is upgraded to 3.6.2.
