CVE-2023-42457 – plone.rest vulnerable to Denial of Service when ++api++ is used many times

https://notcve.org/view.php?id=CVE-2023-42457

plone.rest allows users to use HTTP verbs such as GET, POST, PUT, DELETE, etc. in Plone. Starting in the 2.x branch and prior to versions 2.0.1 and 3.0.1, when the `++api++` traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive. Patches are available in `plone.rest` 2.0.1 and 3.0.1. Series 1.x is not affected. As a workaround, one may redirect `/++api++/++api++` to `/++api++` in one's frontend web server (nginx, Apache). plone.rest permite a los usuarios utilizar verbos HTTP como GET, POST, PUT, DELETE, etc. en Plone. • http://www.openwall.com/lists/oss-security/2023/09/22/2 https://github.com/plone/plone.rest/commit/43b4a7e86206e237e1de5ca3817ed071575882f7 https://github.com/plone/plone.rest/commit/77846a9842889b24f35e8bedc2e9d461388d3302 https://github.com/plone/plone.rest/security/advisories/GHSA-h6rp-mprm-xgcq • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
