CVE-2025-60022 Overview
CVE-2025-60022 is an improper certificate validation vulnerability [CWE-295] affecting the 'デジラアプリ' (Digira) application for iOS prior to version 80.10.00. The application fails to properly validate TLS certificates during encrypted communications. An attacker positioned on the network path can perform a man-in-the-middle (MITM) attack to intercept or modify data exchanged between the app and its backend servers.
Exploitation requires the attacker to be positioned on the same network as the victim, such as an untrusted Wi-Fi hotspot. Successful exploitation compromises the confidentiality and integrity of otherwise encrypted traffic.
Critical Impact
A network-adjacent attacker can eavesdrop on or tamper with encrypted communications between the iOS app and its servers, exposing user data transmitted over the connection.
Affected Products

Technical Details for CVE-2025-60022
Vulnerability Analysis
The vulnerability stems from improper validation of X.509 server certificates during the TLS handshake in the iOS 'デジラアプリ' application. When a mobile application fails to correctly verify certificate chains, hostnames, or trust anchors, it accepts certificates presented by unauthorized parties. This defeats the guarantees that Transport Layer Security is designed to provide.
Certificate validation weaknesses in mobile applications commonly arise from disabled hostname verification, acceptance of self-signed certificates, or overly permissive trust manager implementations. The result is that TLS becomes an obfuscation layer rather than a security control.
Because the exploitation requires the attacker to be positioned between the client and server, opportunistic exploitation typically occurs on public or untrusted networks. Traffic exposed through such attacks may include authentication tokens, session identifiers, and account-related data.
Root Cause
The root cause is categorized under [CWE-295: Improper Certificate Validation]. The iOS application does not enforce complete validation of the server certificate presented during TLS negotiation, allowing forged or attacker-controlled certificates to be accepted as trusted.
Attack Vector
The attack vector is network-based and requires the adversary to be positioned along the communication path. Common scenarios include rogue Wi-Fi access points, ARP spoofing on shared networks, and compromised upstream routers. Once positioned, the attacker presents a fraudulent certificate that the vulnerable app accepts, enabling decryption and modification of traffic.
No verified public exploit code has been released for this vulnerability. Refer to the JVN Security Advisory for vendor-supplied technical details.
Detection Methods for CVE-2025-60022
Indicators of Compromise
- Unexpected TLS certificate fingerprints observed on connections from the iOS application to its backend endpoints.
- Presence of untrusted or self-signed certificates being accepted by mobile devices on corporate networks.
- Anomalous DNS resolutions or ARP table changes on Wi-Fi segments where affected devices operate.
Detection Strategies
- Inspect mobile device traffic through enterprise Wi-Fi monitoring for TLS sessions terminating at non-authoritative endpoints.
- Deploy network detection and response (NDR) rules that flag certificate mismatches for known application backends.
- Correlate mobile device management (MDM) telemetry with network logs to identify affected app versions still in use.
Monitoring Recommendations
- Monitor for use of the 'デジラアプリ' app at versions below 80.10.00 on managed iOS fleets.
- Track TLS handshake anomalies, including unusual certificate authorities appearing in client connections.
- Alert on repeated connections from mobile endpoints to unknown intermediate proxies or gateways.
How to Mitigate CVE-2025-60022
Immediate Actions Required
- Update the 'デジラアプリ' iOS application to version 80.10.00 or later through the App Store.
- Instruct users to avoid connecting to untrusted or public Wi-Fi networks until the application is patched.
- Enforce update policies through mobile device management to ensure the vulnerable app version is removed from managed devices.
Patch Information
The vendor has released version 80.10.00 of the 'デジラアプリ' iOS application, which corrects the certificate validation logic. Users and administrators should install this version to remediate the vulnerability. Details are published in the JVN Security Advisory.
Workarounds
- Route mobile traffic through a trusted VPN to reduce exposure to network-adjacent attackers on untrusted Wi-Fi.
- Disable use of the affected application on managed devices until the update has been applied.
- Restrict corporate-managed iOS devices from joining unauthenticated wireless networks.
