CVE-2018-11307
Description
A vulnerability was discovered in jackson-databind where it would permit deserialization of a malicious object using MyBatis classes when using DefaultTyping. An attacker could use this flaw to achieve content exfiltration and possibly conduct further attacks.
Statement
Red Hat Satellite 6 is not affected by this issue, since Candlepin's java runtime environment does not load MyBatis classes.
Red Hat Virtualization 4 is not affected by this issue, since it does not include MyBatis classes.
Red Hat Fuse 6 and 7 are not directly affected by this issue, as although they do ship the vulnerable jackson-databind component, they do not enable polymorphic deserialization or default typing which are required for exploitability. Their impacts have correspondingly been reduced to Moderate. Future updates may address this flaw.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
