CVE-2019-17531: A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10.
Noroxi assessment
Priority: Plan (action score 41/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 5.3% (FIRST EPSS); higher than 92.6% 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: apache-commons-collections (AlmaLinux:8) 3.2.2-10.module_el8.5.0+2577+9e95fe00; apache-commons-lang (AlmaLinux:8) 2.6-21.module_el8.5.0+2577+9e95fe00; bea-stax-api (AlmaLinux:8) 1.2.0-16.module_el8.5.0+2577+9e95fe00.
Add it to your regular patch cycle. Upgrade to apache-commons-collections (AlmaLinux:8) 3.2.2-10.module_el8.5.0+2577+9e95fe00; apache-commons-lang (AlmaLinux:8) 2.6-21.module_el8.5.0+2577+9e95fe00; bea-stax-api (AlmaLinux:8) 1.2.0-16.module_el8.5.0+2577+9e95fe00 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 2.0.0 through 2.9.10. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the apache-log4j-extra (version 1.2.x) jar in the classpath, and an attacker can provide a JNDI service to access, it is possible to make the service execute a malicious payload.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
