Excessive security or inadvertent censorship? The two

Hello,

I have an old SPIP blog (security updates applied with the latest version) on a shared OVHcloud site that is occasionally blocked by the message "Request blocked due to suspicious activity.".
It's very easy to trigger this block; you just need to mention /etc/passwd or any kind of computer code in a plain text textarea (HTML) (I haven't kept track of which other words were censored).

Are you experiencing the same issue?

This kind of censorship that I suspect is generated by AI :enraged_face:, is it also applied to you on WordPress or elsewhere? How can one discuss computing topics without being censored? I don't want to waste time encoding such text as I've seen done on censoring platforms (Facebook, etc.).

Finally, what is the purpose of this invasive check in a system that is supposed to be private until the articles are published?

Hi,

No censorship and I'm pretty sure the WAF protecting your hosting is doing that.
Try disabling it from your manager and get back to us to let us know.

Seriously, OVH has it out for me: I had all sorts of trouble trying to log into this forum even though I was properly logged into the OVH manager. It kept telling me I couldn't log in with my IP address (even though it comes from my French ISP!?)

As for the blocking of my IP address on my website, on Saturday I was also told about a WAF, a term I wasn’t familiar with. I guess it’s the firewall associated with the subdomain’s address.

So I just disabled that firewall for the subdomain linked to the website. And I’m still getting the same IP block from OVHcloud services when I record the characters "/etc/passwd" in a simple text intended to be displayed in a SPIP article.

Definitely, OVH is mad at me: I had all kinds of trouble connecting to this forum even though I was logged in to the OVH manager. It told me I couldn't log in with my IP address (even though it comes from my French ISP!?)

Yes, that happens to me sometimes too, it's still in the testing phase, @FabL aware of that?

As for the blocking of my IP address on my website, on Saturday I was also told about WAF, a term I didn't know. I guess it's the firewall near the sub‑domain's address.

Web Application Firewall examines the requests that actually pass through to block dangerous actions. It can save you in case of security vulnerabilities in the site's code https://fr.wikipedia.org/wiki/Web_application_firewall#Les_menaces_liées_aux_applications_web

So it's not really a FW in the RZO sense of the term.

I have just disabled this firewall for the sub‑domain linked to the website. And I still get the same IP blocking from OVHcloud services when I record the string "/etc/passwd" in a simple text meant to be displayed in a SPIP article.

So in that case, look rather at SPIP's form sanitization rules.
