CVE-2018-7489 - Remote Code Execution (RCE)

Abstract

FasterXML jackson-databind before 2.7.9.3, 2.8.x before 2.8.11.1 and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.

The Oxygen products incorporate FasterXML jackson-databind as a third-party library. This advisory was opened to address the potential impact of this third-party library vulnerability.
