Security readout for executives and security teams
Plain-English summary
This CVE describes an iOS mobile banking app version 3.0.0 that did not properly verify SSL/TLS certificates. A network-positioned attacker could impersonate the bank service with a crafted certificate and capture sensitive information. The sources do not provide CVSS, vendor remediation details, or evidence of active exploitation.
Executive priority
Prioritize confirmation and retirement because the impact involves banking credentials or sensitive customer data. Urgency is highest if the affected app version remains installed or supported. If the app is no longer used, document the residual risk as historical.
Technical view
The issue is missing X.509 certificate validation in avb-bank-mobile-banking/id592565443 app 3.0.0 for iOS. The reported impact is server spoofing and sensitive information exposure through man-in-the-middle interception using a crafted certificate. The source bundle does not identify affected back-end systems, patch versions, or compensating controls.
Likely exposure
Exposure appears limited to users or organizations still relying on the named iOS app version 3.0.0. Current exposure cannot be confirmed from the provided sources because affected vendor/product metadata is listed as n/a and no fixed version is cited.
Exploitation context
The described attack requires a man-in-the-middle position, such as control of or access to the victim’s network path. The CVE is not listed in KEV, and the provided sources do not claim active exploitation.
Researcher notes
The public record is sparse: no CVSS, CWE, CPE, fixed version, or patch advisory is included. Analysis should stay scoped to the named iOS app version and the TLS certificate validation failure described by CVE and the linked advisory.
Mitigation direction
- Check the vendor or App Store guidance for a fixed mobile app version.
- Retire or block use of app version 3.0.0 if still present.
- Require users to update to a vendor-supported mobile banking app.
- Review mobile app TLS certificate validation in current builds.
- Warn users against conducting banking over untrusted networks until remediated.
Validation and detection
- Confirm whether app id592565443 version 3.0.0 exists in the environment.
- Inventory managed iOS devices for the named app and version.
- Review vendor release notes for certificate validation fixes.
- Test current app builds for proper TLS certificate rejection.
- Check support records for user reports tied to network interception.
