CVE-2023-4680· NVD / CVE Program· CNA HashiCorp

Vault's Transit Secrets Engine Allowed Nonce Specified without Convergent Encryption

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 0.44% (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.
  • Fixed version: HashiCorp Vault 1.12.0, 1.12.11, 1.13.7; HashiCorp Vault Enterprise 1.12.0, 1.12.11, 1.13.7.

Low priority for now. Upgrade to HashiCorp Vault 1.12.0, 1.12.11, 1.13.7; HashiCorp Vault Enterprise 1.12.0, 1.12.11, 1.13.7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

HashiCorp Vault and Vault Enterprise transit secrets engine allowed authorized users to specify arbitrary nonces, even with convergent encryption disabled. The encrypt endpoint, in combination with an offline attack, could be used to decrypt arbitrary ciphertext and potentially derive the authentication subkey when using transit secrets engine without convergent encryption. Introduced in 1.6.0 and fixed in 1.14.3, 1.13.7, and 1.12.11.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
