CVE-2023-37277 XWiki Platform vulnerable to cross-site request forgery (CSRF) via the REST API

What is CVE-2023-37277?

CVE-2023-37277 is a critical vulnerability in Xwiki Xwiki, published on 10 Jul 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The REST API allows executing all actions via POST requests and accepts `text/plain`, `multipart/form-data` or `application/www-form-urlencoded` as content types which can be sent via regular HTML forms, thus allowing cross-site request forgery. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation. For regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari. The vulnerability has been patched in XWiki 14.10.8 and 15.2 by requiring a CSRF token header for certain request types that are susceptible to CSRF attacks.

Weakness: CWE-352
