 https://cloudsek.com/security-flaw-in-atlassian-products-jira-confluencetrello-bitbucket-affecting-multiple-companies/

 

This has been tested. 

Just wanted to highlight here.

Thank you, @Ajay Mishra, for the heads up!

Have you contacted Atlassian directly? Is there any other publicly available information about the vulnerability?

I didn't find anything neither under https://www.atlassian.com/trust/security/advisories, nor under https://www.cvedetails.com/vulnerability-list/vendor_id-3578/Atlassian.html, nor https://jira.atlassian.com/issues/?jql=issuetype%20%3D%20%22Public%20Security%20Vulnerability%22%20ORDER%20BY%20updated%20DESC.

Regards,
K.

Thank you for bringing this up on the Trust & Security Community.  Atlassian's security team is aware of this incident and we have followed security protocol to invalidate affected session tokens. Atlassian is conducting a comprehensive investigation, though our security team has not found evidence of a compromise within our systems or products. No customer action is required at this time. We will share another update once our investigation concludes.

Hi Dawn,

Is this available somewhere as an official message/advice?

Thanks,

Hi Andrew.  The statement above is reiterated on a handful of news articles, see the one below in the UPDATE section: 

https://www.itworldcanada.com/article/atlassian-admins-warned-of-session-cookie-vulnerabilty/517864

 

Atlassian is working on further communications and I can add them to this thread once they are ready!

I saw that @Dan Hranj has recently posted this announcement in this community group: https://community.atlassian.com/t5/Trust-Security-articles/Atlassian-response-to-claims-regarding-session-tokens-cookies/ba-p/2217925.

In essence, Atlassians say:

Our security team did not find a vulnerability in Atlassian Cloud or On-Premise products or a breach of Atlassian systems related to the incident.
