Security readout for executives and security teams

Plain-English summary

CVE-2021-37492 is a confidentiality issue in Ravencoin Core wallet code. In version 4.3.2.1 and earlier, an unauthenticated network attacker could view sensitive information through CWallet::CreateTransactionAll(). The supplied sources do not name the exact information exposed or a confirmed fixed Ravencoin release.

Executive priority

Prioritize inventory and remediation for any Ravencoin Core wallet systems handling meaningful funds or sensitive transaction data. This is high severity but evidence for active exploitation is not supplied, so urgency depends on whether vulnerable wallet services are exposed.

Technical view

The CVE points to src/wallet/wallet.cpp and CWallet::CreateTransactionAll() in Ravencoin Core 4.3.2.1 and earlier. CVSS 3.1 is 7.5, driven by network reachability, low complexity, no privileges, no user interaction, and high confidentiality impact, with no integrity or availability impact recorded.

Likely exposure

Exposure is likely limited to systems running Ravencoin Core wallet software at version 4.3.2.1 or earlier, especially where wallet functionality or related interfaces are reachable by untrusted networks. The affected product metadata is sparse, so asset owners should validate installed Ravencoin Core versions directly.

Exploitation context

The provided bundle does not indicate CISA KEV listing or active exploitation. It also does not provide exploit details. Risk comes from the CVSS characteristics: remote, low-complexity access without privileges or user interaction, affecting confidentiality only.

Researcher notes

The source record is thin: no CWE, no detailed affected CPEs, and no named fixed Ravencoin version. The Bitcoin commit appears as a reference, but the bundle does not prove that a specific Ravencoin release incorporated it. Avoid overclaiming exploitability beyond the CVSS vector.

Mitigation direction

  • Identify all Ravencoin Core wallet deployments and versions.
  • Treat Ravencoin Core 4.3.2.1 and earlier as exposed.
  • Review RavenProject issue and release guidance for a fixed build.
  • Restrict wallet and RPC exposure to trusted hosts only.
  • Move sensitive wallet operations off vulnerable deployments until remediated.

Validation and detection

  • Confirm whether installed Ravencoin Core is 4.3.2.1 or earlier.
  • Check whether local wallet.cpp contains the referenced vulnerable function path.
  • Review network exposure of wallet-related services and RPC interfaces.
  • Verify remediation against RavenProject release notes or project issue updates.
