Description Dimitris Nakos (sokan) 2018-02-27 14:55:34 UTC

FasterXML jackson-databind 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. 

Fix/Commit: https://github.com/FasterXML/jackson-databind/commit/6799f8f10cc78e9af6d443ed6982d00a13f2e7d2

Fixed in 2.8.11.1 (newly released) and 2.9.5 (when it is released).
