createpage-entervariables.action attempted by userName: anonymous - sign of a breach?

Hi all, our Confluence site went down earlier today but came back up following an application restart. In looking through the logs, I found multiple entries that raised my antennae a bit:

2022-02-06 06:01:40,150 ERROR [http-nio-8090-exec-5001 url: /pages/createpage-entervariables.action] [confluence.plugins.synchrony.SynchronyContextProvider] getContextMap

Anonymous access is not enabled for our site, nor are users enabled to set up their own accounts.

Running 7.13.0 on a Linux server. Not seeing anything suspicious or eating up memory in top. Is this cause for concern?

Hi @Lucinda Stroud

Looks like a health check is failing specifically for the security vulnerabilities. Checks if your application version is listed as an affected version for any critical security vulnerabilities published at www.atlassian.com/trust/security/advisories.

Thanks,

Tim

@Lucinda Stroud The version you are on is susceptible to a vulnerability so you should upgrade it. Is your Confluence instance open to the web or do you have to be on your local network or VPN to access it? Are you sure that none of the spaces have anonymous access setup? When the site went down what was happening in the logs at that time? What was happening on the server? Have you worked with your network team to see if there is traffic from unexpected regions? These are all things you should check as you work to identify what actually happened.

Thanks for the responses, @Tim Perrault and @Brant Schroeder .

Anonymous access is disabled globally. Is it still possible for sites to individually allow anonymous access?
The site is open to the web given the needs of our user base.
We upgraded to 7.13.0 in September in response to the CVE-2021-26084 vulnerability; given that the site is not used for displaying code in any way and has no anonymous access granted, we did not upgrade in response to CVE-2021-42574. Upgrading will require us to upgrade our database as well, so I was hoping to delay that somewhat.
I don't have access to the Azure VM that hosts the site, but I am asking the MSP who manages it for any details re: service interruptions or unusual sources of access.

Outage was reported midday PST yesterday, 2/7. Here are logs leading up from that time to the time when I stopped the application in advance of starting it again.

Might be an issue with the collaborative editing. Check this link to see if anything in there will help you.

Lucinda Stroud

Thanks @Tim Perrault - does that mean that you don't have concern with the repeated

userName: anonymous | action: createpage-entervariables

attempts?

Lucinda Stroud

Thanks @Brant Schroeder . Using the Access log, it does look like an IP from Egypt has been attempting to create pages repeatedly, but without success. We've blocked that IP just to be safe. Anonymous access is disabled globally. I don't know if those repeated attempts would have prompted the application to need to be restarted, as there wasn't any upticks in activity until I actually stopped and started the application. We will look into upgrading soon just to be safe.
