Vault KVv2 Metadata and Secret Deletion Policy Bypass Denial-of-Service

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 0.50% (FIRST EPSS).
  • 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.
  • Fixed version: HashiCorp Vault 2.0.0; HashiCorp Vault Enterprise 1.19.16, 1.20.10, 1.21.5.

Low priority for now. Upgrade to HashiCorp Vault 2.0.0; HashiCorp Vault Enterprise 1.19.16, 1.20.10, 1.21.5 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An authenticated user with access to a kvv2 path through a policy containing a glob may be able to delete secrets they were not authorized to read or write, resulting in denial-of-service. This vulnerability did not allow a malicious user to delete secrets across namespaces, nor read any secret data. Fxed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0, 1.21.5, 1.20.10, and 1.19.16.
