Last modified
CVE-2018-7489 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 19.78% chance of exploitation in the next 30 days.
