The penny-flooding protection mechanism in the CTxMemPool::accept method in bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 allows remote attackers to determine associations between wallet addresses and IP addresses via a series of large Bitcoin transactions with insufficient fees.

Security readout for executives and security teams

Plain-English summary

This old Bitcoin Core issue could let a remote party link wallet addresses to IP addresses by abusing fee handling for large transactions. The business impact is privacy exposure, not confirmed fund theft or code execution. The source bundle does not provide a CVSS score or evidence of active exploitation.

Executive priority

Prioritize if the organization operates legacy Bitcoin wallet infrastructure or has privacy-sensitive blockchain operations. Otherwise, urgency is low to moderate because affected software is from 2013-era versions and no active exploitation is cited.

Technical view

CVE-2013-2272 affects bitcoind and Bitcoin-Qt versions before listed 0.4.x, 0.5.x, 0.6.x, and 0.7.x release-candidate boundaries. The weakness is in CTxMemPool::accept penny-flooding protection and can reveal address-to-IP associations through large low-fee transactions. No CWE, CVSS vector, or detailed workaround is provided.

Likely exposure

Exposure is most plausible for organizations still running very old bitcoind or Bitcoin-Qt wallet nodes from the affected version ranges. Modern, maintained Bitcoin clients are not identified as affected in the source bundle.

Exploitation context

The CVE describes remote exploitation for privacy deanonymization. It does not cite CISA KEV, active exploitation, public weaponization, or exploitation prevalence. Treat exploitation status as unconfirmed from the provided sources.

Researcher notes

The useful technical boundary is version-based, not CPE-based, because the source bundle lists n/a affected metadata while the description names bitcoind and Bitcoin-Qt ranges. Evidence is incomplete for severity scoring, CWE classification, exploit maturity, and operational workaround details.

Mitigation direction

  • Inventory any legacy bitcoind and Bitcoin-Qt deployments.
  • Compare versions against the affected ranges listed in the CVE.
  • Move affected clients past the listed fixed release boundaries or current vendor guidance.
  • Retire unsupported wallet nodes where upgrade is not practical.
  • Review wallet-node network exposure and privacy assumptions.

Validation and detection

  • Confirm whether any Bitcoin wallet nodes run bitcoind or Bitcoin-Qt.
  • Record exact client versions for all discovered nodes.
  • Check whether versions fall before the CVE's listed release-candidate boundaries.
  • Verify upgrade status against official Bitcoin project guidance.
  • Document any remaining legacy nodes and compensating controls.
