Vulnerabilities

ProcessWire CMS 3.0.246 allows a low-privileged user with lang-edit to upload a crafted ZIP to Language Support that is auto-extracted without limits prior to validation, enabling resource-exhaustion Denial of Service.

Cross Site Request Forgery vulnerability in ProcessWire v.3.0.229 allows a remote attacker to insert a comment. NOTE: this is disputed by the Supplier because the product intentionally accepts anonymous, unauthenticated comments and thus there are fewer situations in which CSRF would be a useful attack technique. Also, the submitted comments are, by default, held for moderator review.

An issue found in ProcessWire 3.0.210 allows attackers to execute arbitrary code and install a reverse shell via the download_zip_url parameter when installing a new module. NOTE: this is disputed because exploitation requires that the attacker is able to enter requests as an admin; however, a ProcessWire admin is intentionally allowed to install any module that contains any arbitrary code.

ProcessWire v3.0.200 was discovered to contain a Cross-Site Request Forgery (CSRF).

A Directory Traversal vulnerability exits in Processwire CMS before 2.7.1 via the download parameter to index.php.
