CVE-2020-10673
CVSS v2.0
9.3
High
| Vector | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
FasterXML jackson-databind versions 2.0.0 through 2.9.10.3
FasterXML jackson-databind versions 2.6.0 through 2.6.7.3
Description
The issue is related to the interaction between serialization gadgets and typing, specifically with com.caucho.config.types.ResourceRef (also known as caucho-quercus). This can lead to the deserialization of untrusted data, potentially allowing a remote attacker to impact the confidentiality, integrity, and availability of protected information.
Recommendations
For FasterXML jackson-databind versions 2.0.0 through 2.9.10.3, update to version 2.9.10.4 or later.
For FasterXML jackson-databind versions 2.6.0 through 2.6.7.3, update to version 2.6.7.4 or later.
As a temporary workaround, consider restricting the use of the
com.caucho.config.types.ResourceRef class until a patch is available.Exploit
