CVE Additional Information
CVE-2018-7489FasterXML jackson-databind before 220.127.116.11, 2.8.x before 18.104.22.168 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.
