A vulnerability, which was classified as critical, has been found in FasterXML jackson-databind up to 2.7.9.3/2.8.11.1/2.9.5 (Programming Language Software). This issue affects some unknown functionality of the component Default Typing. The manipulation with an unknown input leads to a deserialization vulnerability. Using CWE to declare the problem leads to CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Jodd-db jar (for database access for the Jodd framework) in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

The weakness was released 03/21/2019 as Bug 1671098 as confirmed bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. The identification of this vulnerability is CVE-2018-12022 since 06/07/2018. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.

The commercial vulnerability scanner Qualys is able to test this issue with plugin 176635 (Debian Security Update for jackson-databind (DLA 1703-1)).

Upgrading to version 2.7.9.4, 2.8.11.2 or 2.9.6 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 106601†). Entries connected to this vulnerability are available at VDB-125389, VDB-125417, VDB-128614 and VDB-128615.
