Frequently Asked Questions
1
What level of access does an attacker need?
The attacker does not need to log in. Atlassian warned that the issue can allow an unauthenticated attacker to read specific files.
2
Which products are explicitly identified as affected?
The data explicitly names Atlassian Jira Data Center, Confluence Data Center, Bitbucket Data Center, Bamboo Data Center, and Crowd Data Center. It states that eight Data Center products are affected, but does not identify the remaining three.
3
Could a vulnerability-feed-only process have missed this warning when it was published?
Yes. NVD published items earlier in the observed window and was then silent through the two busiest days, while Atlassian issued this warning. A triage process relying on a national feed may therefore have been reviewing older information rather than this advisory.
