Exploitation Conditions

Exploitation requires three concrete prerequisites: (1) local access to the device sufficient to invoke an Android ADB (Android Debug Bridge) backup of NT OneAPP; (2) the user actively authorizing and confirming the ADB backup on-device (reflected as UI:A in the CVSS vector); and (3) the ability to retrieve the resulting backup archive, which stores usernames and passwords in cleartext. Limiting factors that reduce real-world risk: there is no remote network vector (AV:L), ADB/USB debugging must be reachable, and the mandatory user confirmation of the backup prevents silent, fully automated extraction. Impact is confined to confidentiality of stored credentials.

Impact

This is a genuinely low-to-moderate real-world risk despite the 6.7 CVSS 4.0 score, which is tempered by a demanding local attack chain. The provided CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N) confirms a local attack vector requiring active user interaction (UI:A) and yielding high confidentiality impact only. Although PR:N technically denotes no authentication, exploitation realistically requires physical/ADB access to the device plus the victim explicitly authorizing and confirming an ADB backup - so the 'unauthenticated' label is accurate per the vector but materially gated by UI:A and the ADB prerequisite. No EPSS score, KEV listing, or POC indicator is present in the supplied intelligence, so there is no public exploit identified at time of analysis and no evidence of active exploitation. The confidentiality-only impact (VI:N/VA:N) means no integrity or availability consequence. Net: this is a credential-exposure bug relevant to targeted device-access scenarios (lost/stolen/forensically-accessed phones or malicious-ADB situations), not a remotely wormable or mass-exploitable priority. EPSS/KEV/POC data are all absent rather than negative, so prioritization relies on the vector alone.

Exploit ScenarioDerived

An attacker with physical or ADB access to a device running NT OneAPP persuades or waits for the user to approve an ADB backup, then extracts the generated backup archive. Because credentials are stored in cleartext (CWE-312), the attacker reads plaintext usernames and passwords directly from the backup data. No public exploit code is identified, and the attack requires both local access and user confirmation of the backup.

AnalysisAIv1 – Oct 22, 2026

NT OneAPP stores account usernames and passwords in cleartext within Android backup data, so an attacker with local device access can extract credentials after initiating an ADB backup and obtaining the user's on-device confirmation. The issue is tracked as CWE-312 and rated 6.7 under CVSS 4.0, but the chain requires local access, reachable ADB/USB debugging, and explicit user approval, keeping real-world risk low to moderate. No public exploit was identified at time of analysis.

RemediationAI

No vendor-released patch identified at time of analysis; monitor the TWcert advisories at https://www.twcert.org.tw/en/cp-139-11299-0cbfd-2.html and https://www.twcert.org.tw/tw/cp-132-11298-d9dd5-1.html for an updated NT OneAPP release and contact NewType Infortech for a fixed version. Until a patch is available, disable Android USB debugging and revoke stored ADB authorizations on devices that hold NT OneAPP data; this blocks the adb backup path but breaks developer and diagnostic workflows. Enforce an MDM policy that disables developer options and USB debugging and restricts backup services on managed Android devices, accepting reduced flexibility for field support. Ask the vendor to set android:allowBackup="false" or a restrictive fullBackupContent rule so credential stores are excluded from ADB backups, with the trade-off that legitimate device-migration backups will omit app data. Users should decline unexpected ADB backup confirmation prompts and avoid granting USB debugging to untrusted hosts. Monitor endpoint logs for adb backup invocations and request that NT OneAPP eliminate plaintext credential storage in favor of Android Keystore-backed encryption.

Technical ContextAI · show details

The root cause is CWE-312 (Cleartext Storage of Sensitive Information): NT OneAPP's backup output includes plaintext usernames and passwords rather than encrypting or excluding credential material. Android Debug Bridge (ADB) backup is a developer/diagnostic feature that can produce an archive of application data; when a user confirms the on-device backup prompt, the resulting archive can be retrieved by a local attacker and mined for credentials. The CVSS 4.0 vector AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N reflects a local, unauthenticated attacker who needs user interaction (the backup confirmation) and achieves high confidentiality impact only. The independent assessment maps this to CVSS 3.1 AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, confirming no remote vector, no integrity or availability impact, and a mandatory user-confirmation step. The CPE cpe:2.3:a:newtype_infortech:nt_oneapp:*:*:*:*:*:*:*:* indicates the issue applies across NT OneAPP versions without a version-specific restriction in the available data.
