CVE-2023-33854: Multiple vulnerabilities affect IBM Db2® on Cloud Pak for Data, and Db2 Warehouse on Cloud Pak for Data.

MediumCVSS 5.3 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

IBM Db2 on Cloud Pak for Data and Db2 Warehouse on Cloud Pak for Data versions 4.8, 5.0, 5.1, 5.2, and 5.3 could allow an authenticated user to bypass client-side validation and manipulate input data using man in the middle techniques.
