CVSS v2.0
10
Critical
| Vector | AV: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 prior to 2.9.7
Description
The issue is related to an error in restricting XML external entity references, which can be exploited by a remote attacker to conduct an XML External Entity (XXE) attack using polymorphic deserialization. This can be achieved by leveraging the failure to block unspecified JDK classes from polymorphic deserialization.
Recommendations
For FasterXML jackson-databind versions 2.x prior to 2.9.7, update to version 2.9.7 or later to resolve the issue.
As a temporary workaround, consider restricting the use of polymorphic deserialization to minimize the risk of exploitation.
