CVE-2019-14439: A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2.
Noroxi assessment
Priority: Monitor (action score 33/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 10.8% (FIRST EPSS); higher than 95.8% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: jackson-databind (Debian:10) 2.9.8-3+deb10u1; jackson-databind (Debian:12) 2.9.9.3-1; jackson-databind (Debian:8) 2.4.2-2+deb8u8.
Low priority for now. Upgrade to jackson-databind (Debian:10) 2.9.8-3+deb10u1; jackson-databind (Debian:12) 2.9.9.3-1; jackson-databind (Debian:8) 2.4.2-2+deb8u8 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2. This occurs when Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the logback jar in the classpath.
