https://forum.ablackhole.ru/cgi-bin/yabb2/YaBB.pl?board=&action=RSSrecent

so we therefore turned off that there was another problem with the rss, there was no notice of the admin-buttons, and no, it's someone who attacks me with a bot or scripts-in the error crib

Browsers without RSS support also see version/revision information - Guest or not.

On the screen in Chrome on localhost:

We pride ourselves on the cost (FREE), the features, and the security. Visit <a href="http://www.yabbforum.com" target="_blank">http://www.yabbforum.com</a> to view the latest development information, read YaBB news, and participate in community discussions.<br /><br />Make sure you login to your new forum as an administrator and visit the Admin Center. From there, you can maintain your forum. You'll want to look at all of the settings, membergroups, categories/boards, and security options to make sure they are set properly according to your needs. 

The ONLY WAY currently to disable this is to go into Sources/Sublist.pm and actually comment out

'RSSboard'            => 'RSS.pm&rss_board', 

AND
    

'RSSrecent'           => 'RSS.pm&rss_recent', 

But then, anybody looking at actual urls knows the urls and the Revision number means nothing unless you actually are comparing revisions.

And again, this is NOT a new problem - this is a Chrome problem.

completely disagree with you as well as the first mistake of the rss, the fact is that I do not have any chrome in my opera and the standard edge

critical red vulnerability-requires correction

not an error? -When is it possible to prevent an attacker from putting on the test this version which does not mean and to attack it? -you then delete the old ones from the resource so that they are not available for download

Also, although you claim your forum is 'under attack due to alleged YaBB security inadequacies', sites (not just YaBB) do get slammed by bots trying to get through 403 restrictions AND just trying to cause trouble.

1) - check your RAW server access logs and the server error logs to see if bots are slamming YaBB.pl - evidence if this will be repeated (as in 100s of) 403 errors from the same IP close together in time.

If this is happening, the access log should give you the name of the bot to put into your robots.txt file. (see http://www.robotstxt.org/robotstxt.html.)

Also make sure that, if your server is running Apache 2.4, you've installed the Apache 2.4 mod.

2) Copy your .htaccess file from cgi-bin/yabb2 to your html root folder and make sure the offending bot's IP address is included in the .htaccess file.

While reputable bots, like Google and Bing, stop when they hit a 403, some, like Semrushbot, keep slamming those addresses, creating excessive resource use situations.

robots.txt is a plain ASCII only text file. it just needs to be read (644)

It needs to be placed in your server document root.
