CVE-2020-8840
CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
FasterXML jackson-databind versions 2.0.0 through 2.9.10.2
FasterXML jackson-databind 2.x before 2.6.7.4
FasterXML jackson-databind 2.7.x before 2.7.9.7
FasterXML jackson-databind 2.8.x before 2.8.11.5
FasterXML jackson-databind 2.9.x before 2.9.10.2
Description:
The issue is related to the xbean-reflect/JNDI component of the Jackson-databind library, which lacks certain blocking, as demonstrated by
org.apache.xbean.propertyeditor.JndiConverter. This can allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service by exploiting the vulnerability, which is associated with the restoration of untrusted data structures in memory.Recommendations:
For FasterXML jackson-databind versions 2.0.0 through 2.9.10.2, update to a version that includes the necessary xbean-reflect/JNDI blocking.
For FasterXML jackson-databind 2.x before 2.6.7.4, update to version 2.6.7.4 or later.
For FasterXML jackson-databind 2.7.x before 2.7.9.7, update to version 2.7.9.7 or later.
For FasterXML jackson-databind 2.8.x before 2.8.11.5, update to version 2.8.11.5 or later.
For FasterXML jackson-databind 2.9.x before 2.9.10.2, update to version 2.9.10.2 or later.
As a temporary workaround, consider disabling the
org.apache.xbean.propertyeditor.JndiConverter class until a patch is available.Exploit
