The NIST SP 800-90A default statement of the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point

The NIST SP 800-90A default statement of the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point Q constants with a possible relationship to certain "skeleton key" values, which might allow context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of those values. NOTE: this is a preliminary CVE for Dual_EC_DRBG; future research may provide additional details about point Q and associated attacks, and could potentially lead to a RECAST or REJECT of this CVE.

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.

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.
