Microsoft Entra is a single sign-on tool that allows users to access multiple applications like Jira with one set of login credentials. Researchers recently discovered a high severity vulnerability in one of Entra’s plugins for Jira.

The Entra Jira Single Sign-On plugin contains an elevation of privilege vulnerability. This means that an attacker could potentially exploit the flaw to gain admin access on a user’s Jira account without knowing their password. They could then access and modify projects and issues or add/remove other users.

The vulnerability receives a CVSS score of 9.8 out of 10, meaning it is relatively easy to exploit and can have severe impacts. Attackers would only need to trick a user into clicking a malicious link or visiting a compromised website to exploit it.

If you use Entra to access Jira, you should make sure to update the Entra Jira SSO plugin to the latest version as soon as possible. This will protect your account by fixing the vulnerability. You should also be cautious of any unusual login requests or changes to your Jira profile and password. Using strong and unique passwords can also help prevent account takeovers.

By updating your software and staying alert, you can help protect your Microsoft Entra account from this privilege escalation vulnerability. Let your fellow users know too.
