*cpe:2.3:a:atlassian:confluence:*:*:*:*:*:*:*:* versions from (including) 6.14.0 up to (excluding) 7.4.11 Atlassian has identified a critical Object-Graph Navigation Language (OGNL) injection vulnerability, CVE-2021-26084, affecting their Confluence Server and Confluence Data Center products. Record truncated, showing 500 of 846 characters. The affected versions are before version 6.13.23, from version 6.14.0 before 7.4.11, from version 7.5.0 before 7.11.6, and from version 7.12.0 before 7.12.5.
Confluence server webwork ognl injection code#
In affected versions of Confluence Server and Data Center, an OGNL injection vulnerability exists that would allow an unauthenticated attacker to execute arbitrary code on a Confluence Server or Data Center instance. To check whether this is enabled go to COG > User Management > User Signup Options. The vulnerable endpoints can be accessed by a non-administrator user or unauthenticated user if ‘Allow people to sign up to create their account’ is enabled. View Entire Change Record In affected versions of Confluence Server and Data Center, an OGNL injection vulnerability exists that would allow an authenticated user, and in some instances an unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance. Record truncated, showing 500 of 658 characters.

We recommend the users of the affected software install the necessary Confluence Server security updates as soon as possible to stay protected.CVE Modified by Atlassian 8:15:07 AM Action Confluence Server/Data Center version 7.12.5.Confluence Server/Data Center version 7.11.6.Confluence Server/Data Center version 7.4.11.Confluence Server/Data Center version 6.13.23.If using a Cluster, the script needs to be executed in each node of the cluster.Īn unauthenticated attacker could exploit the Webwork OGNL injection vulnerability to execute arbitrary code on the affected Confluence Server or Data Center instance.Ītlassian Confluence server fixes this vulnerability in the following versions: A restart of the server is required after the script is run successfully. Also, make the scripts executable and run them on the affected instances.

Normally, the bug requires attackers to be logged in to the network to perform the attack, but under certain circumstances, it even allowed unauthenticated attackers to carry out the attack. Only on-premise customers are affected by this vulnerability, and Cloud customers are not vulnerable. Security researcher Benny Jacob discovered this vulnerability which is exploited actively now. The users need to concentrate on the fact that the vulnerable instances can be accessed by an administrator or non-administrator user when the “Allow people to sign up to create their account” option is enabled in the endpoint. The flaw is assigned with the identifier CVE-2021-26084 and is considered critical upon receiving the highest CVSS base score of 9.8. This vulnerability allowed authenticated and, in some instances, even unauthenticated users to execute arbitrary code on the affected Confluence server instance.
Confluence server webwork ognl injection Patch#
Atlassian Confluence recently published a security advisory to patch a critical OGNL(Object-Graph Navigation Language) injectionvulnerability existing in Confluence Server and Data Center instance.
