CVE-2020-4430: IBM Data Risk Manager 2.0.1, 2.0.2, 2.0.3, and 2.0.4 could allow a remote authenticated attacker to traverse directories on the system.

Noroxi assessment

Priority: This week (action score 68/100)

CISA has confirmed exploitation in the wild (Nov 3, 2021). Remediation deadline for US federal agencies: May 3, 2022.
Probability of exploitation in the next 30 days: 68.5% (FIRST EPSS); higher than 99.3% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
