CVE-2020-11620

CVSS v2.0

10

High

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions: FasterXML jackson-databind versions 2.x before 2.9.10.4
Description: The issue is related to the deserialization mechanism in the FasterXML jackson-databind library, specifically with the commons-jelly component. This can allow a remote attacker to execute arbitrary code in the target system. The problem arises from the mishandling of the interaction between serialization gadgets and typing, related to org.apache.commons.jelly.impl.Embedded.
Recommendations: For versions 2.x before 2.9.10.4, update to version 2.9.10.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the org.apache.commons.jelly.impl.Embedded class until a patch is applied.
