Security readout for executives and security teams
Plain-English summary
CVE-2017-20200 concerns Coinomi wallet versions 1.7.0 through 1.7.6 transmitting sensitive information in cleartext. That could expose wallet-related data to a network observer. The reported attack is remote but high complexity and difficult to exploit. Public exploit information exists, but the provided sources do not show confirmed active exploitation.
Executive priority
Moderate priority. This is a confidentiality issue involving cryptocurrency wallet software, but sources describe exploitation as difficult and do not confirm active exploitation. Prioritize if the organization manages crypto assets or permits Coinomi on corporate or executive devices.
Technical view
The record maps to CWE-319/CWE-310: sensitive data transmitted without adequate cryptographic protection. VulDB rates it medium with CVSS 4.0 score 6.3, network attack vector, no privileges or user interaction, high attack complexity, and low confidentiality impact. Affected processing is unspecified in the CVE data.
Likely exposure
Exposure is limited to environments still using Coinomi 1.7.0 through 1.7.6. Risk is most relevant when wallet traffic traverses untrusted or monitored networks. Organizations should treat exposure as asset-specific because the CVE does not identify server-side components or other Coinomi products.
Exploitation context
The exploit has reportedly been publicly disclosed and may be used, according to VulDB. However, the CVE is not listed as KEV in the provided data, and no cited source confirms active exploitation. The vendor reportedly disputed security impact, stating there was no security implication associated with the findings.
Researcher notes
Key gaps remain: the affected processing is not specified, vendor impact is disputed, and no patch is named in the provided sources. Treat public issue and Reddit references as context, not definitive exploitation evidence. Avoid assuming impact beyond Coinomi versions 1.7.0 to 1.7.6.
Mitigation direction
- Inventory Coinomi installations and identify versions 1.7.0 through 1.7.6.
- Check Coinomi vendor guidance for supported versions and any security recommendations.
- Avoid using affected wallet versions on untrusted networks until risk is resolved.
- Limit organizational use of unsupported or legacy cryptocurrency wallet software.
Validation and detection
- Confirm installed Coinomi version on managed devices.
- Review mobile asset inventories for Coinomi 1.7.x usage.
- In a controlled lab, assess whether sensitive wallet data is transmitted cleartext.
- Document whether affected versions are still business-relevant or can be removed.
