Atlassian Questions For Confluence App Hard-coded Credentials Vulnerability
Atlassian Questions For Confluence App has hard-coded credentials, exposing the username and password in plaintext. A remote unauthenticated attacker can use these credentials to log into Confluence and access all content accessible to users in the confluence-users group.
A remote attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2022-08-19 under CISA BOD 22-01.
This is a Use of Hard-coded Credentials (CWE-798) vulnerability in Atlassian Confluence. The Atlassian Questions For Confluence app for Confluence Server and Data Center creates a Confluence user account in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access all content accessible to users in the confluence-users group. This user account is created when installing versions 2.7.34, 2.7.35, and 3.0.2 of the app. Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.
