      This High severity DoS (Denial of Service) vulnerability was introduced in versions 10.1.0, 10.2.0, 11.0.0, 12.0.0, and 12.1.0 of Bamboo Data Center.

      This DoS (Denial of Service) vulnerability, with a CVSS Score of 7.1 and a CVSS Vector of CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H allows an authenticated attacker to cause a resource to be unavailable for its intended users by temporarily or indefinitely disrupting services of a host connected to a network which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.

      Atlassian recommends that Bamboo Data Center customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions:

      • Bamboo Data Center 10.2: Upgrade to a release greater than or equal to 10.2.19

      The National Vulnerability Database provides the following description for this vulnerability: mchange-commons-java is a Java library of shared utility classes used by mchange projects like the c3p0 connection pool. Prior to version 0.6.0, its JNDI ObjectFactory implementation (com.mchange.v2.naming.JavaBeanObjectFactory) will construct objects of arbitrary classes and initialize "JavaBean"-style properties, which for certain classes enables JNDI injection and "deserialization gadgets." Such initialization is unsafe for some classes: for example, setting the contentType property of a Swing JEditorPane to text/html and its text property to HTML containing a stylesheet <link> will provoke an HTTP GET on an arbitrary URL, potentially from within a trusted security domain. The problem is aggravated by the library's ReferenceIndirector, through which malicious JNDI Reference objects can be smuggled in for dereferencing wherever an application reads a Java-serialized object. This has been resolved in version 0.6.0.
