On Wednesday 23rd of June, cyber-security experts uncovered key vulnerabilities in the Atlassian project and software development platform that might have been exploited to take over the account and control certain apps connected via its single sign-on (SSO) capabilities. The vulnerabilities are due to Atlassian using SSO to ensure the uninterrupted navigation of the above-mentioned domains, thereby attempting to create a possible attack scenario involving the use of XSS and CSRF to inject malicious code into the portal and leveraging a session fixation error in the event of a valid user session. Though these vulnerabilities have been patched. On January 08, 2021, the Australian company delivered a patch for its upgrades, after Atlassian was notified of the problem. The issues in the sub-domains include – jira.atlassian.com confluence.atlassian.com getsupport.atlassian.com partners.atlassian.com developer.atlassian.com support.atlassian.com training.atlassian.com "With just one click, an attacker could have used the flaws to get access to Atlassian's to publish Jira system and get sensitive information, such as security issues on Atlassian cloud, Bitbucket, and on-premise products," Check Point Research stated. The appropriate exploitation of such vulnerabilities could escalate to an attack through a supply chain where the attacker can take over an account, take illegal measures on behalf of the victim, modify pages of Confluence, access Jira tickets, and even inject malicious implants to perpetrate further attacks. In other words, an attacker can deceive a user by clicking an Atlassian link that has been created to carry out a malicious payload, which can be utilized by the wrong player to log into the victim's account and gain confidential information. Moreover, the attacker can regulate a Bitbucket account with a J ..
