CVE-2019-25354 Overview
CVE-2019-25354 is a denial of service vulnerability affecting iSmartViewPro version 1.3.34, an iOS application published by Smarteye Group for remote camera management. The flaw resides in the camera identifier (DID) and password input fields, which fail to enforce proper length validation. Attackers who paste a 257-character buffer into these fields trigger an unhandled condition that crashes the application. The issue is classified under [CWE-120] (Buffer Copy without Checking Size of Input). Exploitation requires local user interaction on the device running the vulnerable iOS app, limiting impact to availability of the application itself.
Critical Impact
An attacker with local access to the iOS device can reliably crash the iSmartViewPro application by submitting an oversized string to the camera DID or password input fields, disrupting access to connected camera feeds.
Affected Products
- iSmartViewPro for iOS, version 1.3.34
- Smarteye Group iSmartViewPro (App Store distribution)
- Earlier and related builds that share the same input handling logic may also be affected

Technical Details for CVE-2019-25354
Vulnerability Analysis
The vulnerability stems from improper bounds checking on user-supplied input within the iSmartViewPro iOS application. When a user pastes a string of 257 characters or more into the camera DID field or password field, the application fails to validate or truncate the input before processing it. The result is an unhandled exception that terminates the application process. The flaw is local in nature and requires user interaction, since input must be entered directly into the application's UI fields. Exploitation does not yield code execution, privilege escalation, or data disclosure. Impact is limited to availability of the affected application, preventing operators from monitoring or managing connected cameras until the app is restarted.
Root Cause
The root cause is a missing length check on the camera identifier and password fields. The application copies user-supplied input into a fixed-size buffer without verifying that the source length fits within the destination. Pasting 257 bytes exceeds the expected boundary and produces the crash documented in Exploit-DB #47662.
Attack Vector
Exploitation is local and requires user interaction. An attacker with physical or remote-control access to the iOS device opens iSmartViewPro, navigates to the camera configuration screen, and pastes an oversized string into the DID or password field. The application crashes immediately. Because the attack requires UI interaction on the target device, remote exploitation over a network is not possible. Refer to the VulnCheck Advisory on iSmartViewPro for additional context.
Detection Methods for CVE-2019-25354
Indicators of Compromise
- Repeated unexpected terminations of the iSmartViewPro process on iOS devices
- iOS crash logs referencing the iSmartViewPro bundle identifier with exception type related to input handling or memory access
- User reports of the app closing immediately after entering or pasting camera credentials
Detection Strategies
- Review iOS device crash diagnostics under Settings > Privacy & Security > Analytics & Improvements > Analytics Data for entries matching iSmartViewPro
- Correlate mobile device management (MDM) telemetry for application crash events on devices with iSmartViewPro 1.3.34 installed
- Inventory iOS endpoints to identify installations of iSmartViewPro version 1.3.34 as exposure indicators
Monitoring Recommendations
- Track installed application versions across managed iOS fleets and flag instances of iSmartViewPro 1.3.34
- Monitor crash-reporting feeds and helpdesk tickets for repeated iSmartViewPro failures, which may indicate exploitation attempts
- Alert on anomalous patterns of camera service disruption that correlate with mobile app crashes
How to Mitigate CVE-2019-25354
Immediate Actions Required
- Identify iOS devices running iSmartViewPro 1.3.34 through MDM inventory
- Update the application to the latest available version from the Apple App Store if a fixed build has been published by Smarteye Group
- Restrict physical access to devices running the vulnerable application in shared or kiosk environments
Patch Information
No vendor patch advisory has been published in the references associated with this CVE. Administrators should check the App Store listing for newer versions of iSmartViewPro and contact Smarteye Group directly to confirm whether a fixed release addresses the input length validation flaw documented in Exploit-DB #47662.
Workarounds
- Avoid pasting untrusted strings into the camera DID or password fields of iSmartViewPro
- Enforce manual entry of camera identifiers with length validation performed by the operator
- Consider replacing iSmartViewPro 1.3.34 with an alternative camera management application until a fixed version is confirmed available
- Apply MDM policies that restrict clipboard sharing on devices used for critical camera monitoring tasks
