CVE-2019-25701 Overview
Easy Video to iPod Converter 1.6.20 contains a local buffer overflow vulnerability in the user registration field that allows local attackers to overwrite the structured exception handler (SEH). Attackers can input a crafted payload exceeding 996 bytes in the username field to trigger SEH overwrite and execute arbitrary code with user privileges.
Critical Impact
Local attackers can exploit this buffer overflow to achieve arbitrary code execution by overwriting the structured exception handler through the registration username field.

Technical Details for CVE-2019-25701
Vulnerability Analysis
This vulnerability is classified as CWE-787 (Out-of-bounds Write), a memory corruption flaw that occurs when the application writes data past the boundaries of allocated memory buffers. The vulnerability exists in the user registration functionality of Easy Video to iPod Converter, specifically within the username input field processing routine.
When a user enters registration data, the application fails to properly validate the length of the username input before copying it into a fixed-size stack buffer. This lack of bounds checking allows an attacker to provide input exceeding the expected buffer size, resulting in memory corruption beyond the allocated space.
The impact of this vulnerability is significant as it allows complete compromise of confidentiality, integrity, and availability at the user privilege level. Since the attack requires local access and no privileges, an attacker with physical or local access to a system running this software could leverage this flaw for code execution.
Root Cause
The root cause of this vulnerability is improper input validation in the registration handler. The application allocates a fixed-size buffer on the stack for storing the username but does not verify that user-supplied input fits within the allocated space before performing the copy operation. This classic programming error enables stack-based buffer overflow attacks.
Attack Vector
The attack is performed locally by interacting with the application's registration dialog. An attacker crafts a malicious payload of more than 996 bytes and enters it into the username registration field. This oversized input overwrites adjacent stack memory, including the Structured Exception Handler (SEH) chain.
By carefully constructing the payload, an attacker can overwrite the SEH pointer with an address of their choosing. When an exception occurs (which can be triggered as part of the exploit), Windows transfers execution to the attacker-controlled address, enabling arbitrary code execution.
The attack requires no authentication or special privileges, only local access to run the vulnerable application. The exploitation complexity is low, making this a straightforward buffer overflow attack scenario.
Detection Methods for CVE-2019-25701
Indicators of Compromise
- Presence of Easy Video to iPod Converter version 1.6.20 installed on systems
- Crash dumps or application errors from easy_video_to_ipod.exe indicating stack corruption
- Unusual process behavior or child processes spawned from the application
Detection Strategies
- Monitor for crashes or abnormal termination of the Easy Video to iPod Converter application
- Implement endpoint detection rules to identify buffer overflow exploitation patterns targeting SEH chains
- Deploy application whitelisting to prevent unauthorized or legacy software from running
Monitoring Recommendations
- Conduct software inventory audits to identify systems running this vulnerable application
- Enable crash reporting and analysis to detect exploitation attempts
- Monitor for suspicious activity following application crashes that may indicate successful exploitation
How to Mitigate CVE-2019-25701
Immediate Actions Required
- Remove or uninstall Easy Video to iPod Converter version 1.6.20 from all systems
- Replace with alternative video conversion software that is actively maintained
- If removal is not immediately possible, restrict local access to systems running this software
Patch Information
No vendor patch is available for this vulnerability. The software appears to be legacy or unmaintained. Organizations should consider the following resources for additional information:
Workarounds
- Uninstall the vulnerable software as no patch is available
