Atlassian has published a security advisory warning of a critical vulnerability in its Jira software that could be abused by a remote, unauthenticated attacker to circumvent authentication protections.
Tracked as CVE-2022-0540, the flaw is rated 9.9 out of 10 on the CVSS scoring system and resides in Jira’s authentication framework, Jira Seraph. Khoadha of Viettel Cyber Security has been credited with discovering and reporting the security weakness.
“A remote, unauthenticated attacker could exploit this by sending a specially crafted HTTP request to bypass authentication and authorization requirements in WebWork actions using an affected configuration,” Atlassian noted.
The flaw affects the following Jira products -
Fixed Jira and Jira Service Management versions are 8.13.18, 8.20.6, and 8.22.0 and 4.13.18, 4.20.6, and 4.22.0.
Atlassian also noted that the flaw affects first and third-party apps only if they are installed in one of the aforementioned Jira or Jira Service Management versions and that they are using a vulnerable configuration.
Users are strongly recommended to update to one of the patched versions to mitigate potential exploitation attempts. If immediate patching isn’t an option, the company is advising updating the affected apps to a fixed version or disabling them altogether.
It’s worth noting that a critical remote code execution flaw in Atlassian Confluence (CVE-2021-26084, CVSS score: 9.8) was actively weaponized in the wild last year to install cryptocurrency miners on compromised servers.
