GHSA-9mxf-g3x6-wv74 CVE-2018-14721

Server-Side Request Forgery (SSRF) in jackson-databind

Critical Maven

Severity: 10.0 / 10; Critical · CVSS 3.0
Exploit chance (EPSS): 10.46%; Chance of exploitation in the next 30 days. Higher than 95.75% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-918 Server-Side Request Forgery (SSRF)
Fix: 2.9.7; Upgrade com.fasterxml.jackson.core:jackson-databind to this version or later

Description

FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to conduct server-side request forgery (SSRF) attacks by leveraging failure to block the axis2-jaxws class from polymorphic deserialization.

Affected versions

Maven

Package	Vulnerable	Fixed in
com.fasterxml.jackson.core:jackson-databind	`>= 2.9.0, < 2.9.7`	`2.9.7`
com.fasterxml.jackson.core:jackson-databind	`>= 2.8.0, < 2.8.11.3`	`2.8.11.3`
com.fasterxml.jackson.core:jackson-databind	`>= 2.7.0, < 2.7.9.5`	`2.7.9.5`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

com.fasterxml.jackson.core:jackson-databind Maven → `2.9.7`

<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.7</version></dependency>
