  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue SQLmap attack detected (ID: 218500) on blank page

Hi,

I just created new subdomain. I didn't do anything on that page but I already get forbidden 403 code. I found out that Web Application Firewall (builtin from Plesk) threw the error:
Code:
ModSecurity: Access denied with code 403 (phase 2). Pattern match "[\\\\[\\\\]\\\\x22',()\\\\.]{10}$|\\\\b(?:union\\\\sall\\\\sselect\\\\s(?:(?:null|\\\\d+),?)+|order\\\\sby\\\\s\\\\d{1,4}|(?:and|or)\\\\s\\\\d{4}=\\\\d{4}|waitfor\\\\sdelay\\\\s'\\\\d+:\\\\d+:\\\\d+'|(?:select|and|or)\\\\s(?:(?:pg_)?sleep\\\\(\\\\d+\\\\)|\\\\d+\\\\s?=\\\\s?(?:dbms_pipe\\\\.receive_message\\\\ ..." at REQUEST_COOKIES:sbjs_current_add. [file "/etc/apache2/modsecurity.d/rules/comodo_free/22_SQL_SQLi.conf"] [line "64"] [id "218500"] [rev "18"] [msg "COMODO WAF: SQLmap attack detected
It's a blank page with a default index.html file. Should I be worried that my Plesk-instance may be infected? Or is this a know issue and I have to remove the rule 218500?

Do you also have such issue?

Best regards
Floh
 
It would be pretty strange if that ModSecurity rule triggered on a blank page. Does the default index page contain any content or is it an completely empty file?
 
Does the rule trigger when you access the page, or did you just find that in the logs? If the latter, is it a POST attempt?
 
The log excerpt shown above is just one ordinary SQL injection rule where SQL statements are attached to a URL as parameters. This cannot be triggered by simply opening index.html or index.php. No need to worry. It must be a log entry caused by an external source.
 
Is is save to switch of the security rule, because I am facing the same challenge after migrating wordpress site to plesk, I tried uploading the website file to a brand new wordpress site yet it returns 403 forbidden error. When I checked the Web Application Firewall log it discovered it was blocked by it. Should I switch off the rule ID ?
