- Summary
- plone.rest vulnerable to Denial of Service when ++api++ is used many times
- Details
-
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 inplone.rest2.0.1 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). - References
