Summary
by MITRE • 04/12/2026
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. Attackers can input a crafted payload exceeding 996 bytes in the username field to trigger SEH overwrite and execute arbitrary code with user privileges.

The vulnerability identified as CVE-2019-25701 represents a critical local buffer overflow flaw within Easy Video to iPod Converter version 1.6.20. This software application falls under the category of multimedia conversion tools that facilitate video file processing for portable media devices. The vulnerability specifically targets the user registration functionality, creating a pathway for malicious exploitation through improper input validation mechanisms. The flaw manifests when the application processes user-provided data without adequate bounds checking, particularly within the username field validation logic.
The technical implementation of this buffer overflow occurs due to insufficient boundary validation in the registration form processing module. When an attacker provides a crafted payload exceeding 996 bytes in the username field, the application fails to properly manage memory allocation for the input buffer. This deficiency allows the attacker to overwrite adjacent memory locations, specifically targeting the structured exception handler (SEH) chain that governs error handling within the windows application environment. The SEH overwrite represents a sophisticated exploitation technique that leverages the Windows exception handling mechanism to redirect program execution flow.
The operational impact of this vulnerability extends beyond simple code execution, as it enables attackers to perform arbitrary code injection with the privileges of the currently logged-in user. This local privilege escalation capability significantly increases the potential damage scope since the attacker operates within the user context without requiring elevated system permissions. The vulnerability's local nature means that exploitation requires physical access to the target system or the ability to execute malicious code in the user's session context, making it particularly concerning for environments where user access is not strictly controlled.
From a cybersecurity perspective, this vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and CWE-122, which addresses heap-based buffer overflow scenarios. The attack vector specifically maps to the ATT&CK technique T1059.001, which encompasses command and scripting interpreter execution, as the successful exploitation would likely involve injecting malicious code that executes within the application's process space. The vulnerability's characteristics also relate to T1068, which covers local privilege escalation techniques, as the attacker gains elevated privileges through the SEH overwrite mechanism.
Mitigation strategies for this vulnerability should include immediate software patching from the vendor, as the most effective defense against this specific flaw. System administrators should implement application whitelisting policies to restrict execution of untrusted binaries and ensure that the vulnerable software is removed from systems where it is not essential. Additionally, input validation controls should be enhanced through proper bounds checking and memory management practices. Network segmentation and privilege separation techniques can help limit the potential impact of successful exploitation attempts, while regular security assessments should identify similar vulnerabilities in other legacy applications that may present similar buffer overflow risks.
