The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
jackson-databind: Serialization gadgets in classes of the ehcache package (CVE-2019-17267)
A flaw was discovered in jackson-databind in versions before 2.9.10, 2.8.11.5 and 2.6.7.3, where it would permit polymorphic deserialization of a malicious object using commons-configuration 1 and 2 JNDI classes.
An attacker could use this flaw to execute arbitrary code. (CVE-2019-14892)
A flaw was discovered in FasterXML jackson-databind in all versions before 2.9.10 and 2.10.0, where it would permit polymorphic deserialization of malicious objects using the xalan JNDI gadget when used in conjunction with polymorphic type handling methods such as enableDefaultTyping()
or when @JsonTypeInfo is using Id.CLASS
or Id.MINIMAL_CLASS
or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.
(CVE-2019-14893)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
