CVE-2018-25098: blockmason credit-protocol UCAC CreditProtocol.sol executeUcacTx denial of service

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in blockmason credit-protocol. It has been declared as problematic. Affected by this vulnerability is the function executeUcacTx of the file contracts/CreditProtocol.sol of the component UCAC Handler. The manipulation leads to denial of service. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named 082e01f18707ef995e80ebe97fcedb229a55efc5. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-252799. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Security readout for executives and security teams

Plain-English summary

CVE-2018-25098 is a medium-severity denial-of-service issue in Blockmason credit-protocol, specifically the UCAC handler in CreditProtocol.sol. The project is unsupported and does not use versioning, so exposure depends on whether your organization still runs or relies on this code or a fork.

Executive priority

Treat this as a moderate priority unless the protocol is still used in production or supports financial workflows. Unsupported status increases operational risk because fixes, affected versions, and vendor support are limited.

Technical view

The CVE identifies CWE-404 in executeUcacTx within contracts/CreditProtocol.sol. Manipulation can cause denial of service with low availability impact. CVSS 3.1 is 4.3, AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L. A patch commit is named, but affected and unaffected releases are unavailable.

Likely exposure

Exposure is likely limited to organizations using Blockmason credit-protocol, deployed derivatives, or forks containing the vulnerable UCAC handler. The product has no versioning, and sources state it is no longer supported, making inventory and code comparison necessary.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not listed as KEV. The CVSS vector suggests adjacent access, low complexity, no privileges, and no user interaction, but the documented impact is limited to availability.

Researcher notes

Evidence is sparse: no versioning, unavailable affected-release boundaries, and no cited exploitation. Analysis should focus on code provenance, fork lineage, deployed contract equivalence, and whether the named patch is present.

Mitigation direction

  • Inventory any use of Blockmason credit-protocol or forks.
  • Compare local code with patch commit 082e01f18707ef995e80ebe97fcedb229a55efc5.
  • Apply the referenced patch where the code remains in use.
  • If unsupported code is business-critical, plan retirement or replacement.
  • Check current vendor or community guidance before operational changes.

Validation and detection

  • Search repositories for contracts/CreditProtocol.sol and executeUcacTx.
  • Confirm whether deployed artifacts include the vulnerable UCAC handler logic.
  • Review PR 33 and the patch commit against local code.
  • Run availability-focused regression tests for patched UCAC transaction handling.
  • Document any remaining unsupported deployments and compensating controls.
