CVE-2019-12814: Debian Linux

Medium severity, CVSS 5.9. EPSS: 10.9% chance of exploitation in the next 30 days.

A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x through 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM 1.x or 2.x jar in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server.

Affected products

• Debian Debian Linux: version 8.0 only
• Fasterxml Jackson-Databind: from 2.0.0, before 2.6.7.3 (fixed in 2.6.7.3); from 2.7.0, before 2.7.9.6 (fixed in 2.7.9.6); from 2.8.0, before 2.8.11.4 (fixed in 2.8.11.4); from 2.9.0, before 2.9.9.2 (fixed in 2.9.9.2)
