Security Bulletin: IBM Workload Scheduler potentially affected by multiple vulnerabilities in jackson-databind (CVE-2022-42003, CVE-2022-42004)

Summary

FasterXML jackson-databind is vulnerable to denial of service attacks that can potentially affect IBM Workload Scheduler 9.5 and IBM Workload Scheduler 10.1

Vulnerability Details

CVEID:CVE-2022-42003
**DESCRIPTION:**FasterXML jackson-databind is vulnerable to a denial of service, caused by a lack of a check in the primitive value deserializers when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. By sending a specially-crafted request using deep wrapper array nesting, a local attacker could exploit this vulnerability to exhaust all available resources.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/237662 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-42004
**DESCRIPTION:**FasterXML jackson-databind is vulnerable to a denial of service, caused by a lack of a check in in the BeanDeserializer._deserializeFromArray function. By sending a specially-crafted request using deeply nested arrays, a local attacker could exploit this vulnerability to exhaust all available resources.
