对于Web解决方案使用RinRuby是否安全？

Question

I recall from some meetups I've attended in NYC that people in bell labs were trying to work on potential security issues with R on the web. There was potential risks of code injection into a Web App if R sessions were kept alive for the user.

Now, this was presented in the context of HTML 5 and PHP, but I don't see how it would be different when using RoR with the RinRuby gem. Is there a set of rules we as developers should follow to avoid common security pitfalls when using this gem?

Answer 1

R in general was not built with security in mind (see also this preprint at arXiv by Jeroen Ooms). It is also notorious for flaky parsing of numbers .

Judging from the source code (which was not updated for 2 years (!)) RinRuby doesn't seem to provide any kind of isolation from injection either - bare-bones eval is a gateway to hell, they say :)

Thus, it falls upon your shoulders to follow eg OWASP guidelines to avoid injection by carefully validating, parameterizing and whitelisting the input. Having in mind the above-mentioned quirks in parsing numbers, you have to restrict inputs to sane intervals.

Just my 2 cents...
