Atlassian threat watch

Atlassian Jira Server and Data Center contain a path traversal vulnerability that allows a remote attacker to read particular files in the /WEB-INF/web.xml endpoint.

Atlassian Confluence Data Center and Server contain an unauthenticated OGNL template injection vulnerability that can lead to remote code execution. Known ransomware use: Known.

Atlassian Confluence Data Center and Server contain an improper authorization vulnerability that can result in significant data loss when exploited by an unauthenticated attacker. There is no impact on confidentiality since the attacker cannot exfiltrate any data. Known ransomware use: Known.

Atlassian Confluence Data Center and Server contains a broken access control vulnerability that allows an attacker to create unauthorized Confluence administrator accounts and access Confluence. Known ransomware use: Known.

Multiple API endpoints of Atlassian Bitbucket Server and Data Center contain a command injection vulnerability where an attacker with access to a public Bitbucket repository, or with read permissions to a private one, can execute code by sending a malicious HTTP request.

Atlassian Questions For Confluence App has hard-coded credentials, exposing the username and password in plaintext. A remote unauthenticated attacker can use these credentials to log into Confluence and access all content accessible to users in the confluence-users group.

Atlassian Confluence Server and Data Center contain a remote code execution vulnerability that allows for an unauthenticated attacker to perform remote code execution. Known ransomware use: Known.

Affected versions of Atlassian Confluence Server allow remote attackers to view restricted resources via a pre-authorization arbitrary file read vulnerability in the /s/ endpoint. Known ransomware use: Known.

Atlassian Jira Server and Data Center contain a server-side template injection vulnerability which can allow for remote code execution.

Atlassian Confluence Server and Data Center contain a server-side template injection vulnerability that may allow an attacker to achieve path traversal and remote code execution. Known ransomware use: Known.

Atlassian Confluence Server and Data Center contain a path traversal vulnerability in the downloadallattachments resource that may allow a privileged, remote attacker to write files. Exploitation can lead to remote code execution.

Atlassian Confluence Server and Data Server contain an Object-Graph Navigation Language (OGNL) injection vulnerability that may allow an unauthenticated attacker to execute code. Known ransomware use: Known.

Atlassian Crowd and Crowd Data Center contain a remote code execution vulnerability resulting from a pdkinstall development plugin being incorrectly enabled in release builds. Known ransomware use: Known.

Bamboo did not check that the name of a branch in a Mercurial repository contained argument parameters. An attacker who has permission to create a repository in Bamboo, edit an existing plan that has a non-linked Mercurialrepository, create or edit a plan when there is at least one linked Mercurial repository that the attacker has permission to use, or commit to a Mercurial repository used by a Bamboo plan which has branch detection enabled can execute code of their choice on systems that run a vulnerable version of Bamboo Server. Versions of Bamboo starting with 2.7.0 before 6.1.6 (the fixed version for 6.1.x) and from 6.2.0 before 6.2.5 (the fixed version for 6.2.x) are affected by this vulnerability.

It was possible for double OGNL evaluation in FreeMarker templates through Struts FreeMarker tags to occur. An attacker who has restricted administration rights to Bamboo or who hosts a website that a Bamboo administrator visits, is able to exploit this vulnerability to execute Java code of their choice on systems that run a vulnerable version of Bamboo. All versions of Bamboo before 6.1.6 (the fixed version for 6.1.x) and from 6.2.0 before 6.2.5 (the fixed version for 6.2.x) are affected by this vulnerability.

It is possible to bypass the bitbucket auto-unapprove plugin via minimal brute-force because it is relying on asynchronous events on the back-end. This allows an attacker to merge any code into unsuspecting repositories. This affects all versions of the auto-unapprove plugin, however since the auto-unapprove plugin is not bundled with Bitbucket Server it does not affect any particular version of Bitbucket.

Atlassian Fisheye and Crucible versions less than 4.4.3 and version 4.5.0 are vulnerable to argument injection through filenames in Mercurial repositories, allowing attackers to execute arbitrary code on a system running the impacted software.

The Hipchat for Mac desktop client is vulnerable to client-side remote code execution via video call link parsing. Hipchat for Mac desktop clients at or above version 4.0 and before version 4.30 are affected by this vulnerability.

A Server Side Request Forgery (SSRF) vulnerability could lead to remote code execution for authenticated administrators. This issue was introduced in version 2.2.0 of Hipchat Server and version 3.0.0 of Hipchat Data Center. Versions of Hipchat Server starting with 2.2.0 and before 2.2.6 are affected by this vulnerability. Versions of Hipchat Data Center starting with 3.0.0 and before 3.1.0 are affected.

Bamboo before 6.0.5, 6.1.x before 6.1.4, and 6.2.x before 6.2.1 had a REST endpoint that parsed a YAML file and did not sufficiently restrict which classes could be loaded. An attacker who can log in to Bamboo as a user is able to exploit this vulnerability to execute Java code of their choice on systems that have vulnerable versions of Bamboo.
