02 Description

Data Distribution Service (DDS) Chain of Trust (CoT) violation vulnerability in Open DDS

03 Exploitation and scoring

Exploitation
Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
SSVC decision
  • ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.28% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 21.2% of scored records. A rank, not a probability.
NVD base score
8.2 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L
NVD analysis status
Deferred. NVD last modified this record on 2026-06-17.
Red Hat severity
No Red Hat rating. Red Hat rates the CVEs that affect its products.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation

Instead of including the Permission CA into the store of trusted certificates to use for chain verification, the Permission CA (and only the Permission CA) should be included in the set of certificates in which to search for signer's certificates. The store of trusted certificates to use for chain verification should then also be set to null. 2) With the store of trusted certificates to use for chain verification set to null, the PKCS7_NOVERIFY flag should then be enabled so any signer's certificates (i.e. only the Permission CA) is not chain verified. 3) Given that only a valid signer's certificate must be the Permission CA, the PKCS7_NOINTERN flag should then be enabled so any set of certificates in the message itself are not searched when locating the signer's certificates.
