Vulnerability in Jira Service Management Server and Data Center - CVE-2023-22501

Dear customer,

on the 1st of February 2023 at 8 PM CEST, Atlassian issued a Security Advisory for Jira Service Management Server and Jira Service Management Data Center.
Atlassian Cloud sites are not affected. If your Jira site is accessed via an domain, it is hosted by Atlassian and you are not affected by the vulnerability.

What you need to know

This advisory discloses a critical severity security vulnerability which was introduced in version 5.3.0 of Jira Service Management Server et Data Center. 

An authentication vulnerability was discovered in Jira Service Management Server and Data Center which allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances. With public signup enabled on a Jira Service Management instance, an attacker could gain access to signup tokens sent to users with accounts that have never been logged into. Access to these tokens can be obtained in two cases:

  • If the attacker is included on Jira issues or requests with these users, or

  • If the attacker is forwarded or otherwise gains access to emails containing a “View Request” link from these users.

Bot accounts are particularly susceptible to this scenario. On instances with single sign-on, external customer accounts can be affected in projects where anyone can create their own account.
