Customers who have upgraded Bamboo to version 6.1.6 or 6.2.5 are not affected. Customers who have downloaded and installed Bamboo less than 6.1.6 (the fixed version for 6.1.x) or who have downloaded and installed Bamboo >= 6.2.0 but less than 6.2.5 (the fixed version for 6.2.x) please upgrade your Bamboo installations immediately to fix these vulnerabilities. Remote code execution through OGNL double evaluation (CVE-2017-14589) Severity: Atlassian rates the severity level of this vulnerability as critical, according to the scale published in our Atlassian severity levels. The scale allows us to rank the severity as critical, high, moderate or low. This is our assessment and you should evaluate its applicability to your own IT environment. Description: 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. Versions of Bamboo before version 6.1.6 (the fixed version for 6.1.x) and from version 6.2.0 before 6.2.5 (the fixed version for 6.2.x) are affected by this vulnerability.

The scale allows us to rank the severity as critical, high, moderate or low. This is our assessment and you should evaluate its applicability to your own IT environment. Description: Bamboo did not check that the name of a branch in a Mercurial repository contained argument parameters. An attacker who has permission to do one or more of the following - create a repository in Bamboo, edit an existing plan in Bamboo that has a non-linked Mercurial repository, create or edit a plan in Bamboo 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.
