CVE-2019-25565 in Magic Iso Maker
Summary
by MITRE • 03/21/2026
Magic Iso Maker 5.5 build 281 contains a buffer overflow vulnerability in the Serial Code registration field that allows local attackers to crash the application by submitting an oversized input. Attackers can generate a file containing 5000 bytes of data, paste it into the Serial Code field during registration, and trigger a denial of service condition that crashes the application.

The vulnerability identified as CVE-2019-25565 represents a critical buffer overflow flaw within Magic Iso Maker version 5.5 build 281 that specifically targets the Serial Code registration field. This issue demonstrates a classic software security weakness where insufficient input validation allows maliciously crafted data to exceed the allocated buffer space, leading to unpredictable application behavior and system instability. The vulnerability resides in the application's registration mechanism where user-supplied serial code data is processed without adequate bounds checking, creating an exploitable condition that can be readily triggered by local attackers.
The technical implementation of this vulnerability stems from the application's failure to properly validate the length of input data submitted through the Serial Code field during the registration process. When an attacker provides a payload containing 5000 bytes of data, the application's internal buffer handling mechanisms cannot accommodate this excessive input size, resulting in memory corruption that ultimately leads to application crash. This buffer overflow condition occurs because the software allocates a fixed-size buffer for serial code processing but fails to implement proper input length verification before copying data into this allocated memory space. The vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions where insufficient bounds checking allows data to overwrite adjacent memory locations.
From an operational perspective, this vulnerability presents a significant risk to users of Magic Iso Maker 5.5 build 281 as it enables local attackers to achieve denial of service conditions that completely disrupt the application's functionality. The attack requires minimal technical expertise since it only involves copying a large data payload into the registration field, making it particularly dangerous in environments where users might be tricked into entering malicious data. The impact extends beyond simple application crashes as the buffer overflow could potentially be exploited to execute arbitrary code, though the current description indicates the primary effect is denial of service. This vulnerability affects the application's availability and reliability, potentially disrupting legitimate users who require the software for ISO image creation and management tasks.
The exploitation of this vulnerability aligns with ATT&CK technique T1499.004, which covers the use of denial of service attacks against applications and systems. Security professionals should recognize this as a prime example of why input validation and buffer management are critical components of secure software development practices. Organizations using Magic Iso Maker should immediately implement mitigations including updating to patched versions of the software, implementing application whitelisting policies to restrict execution of vulnerable applications, and conducting security awareness training for users to prevent social engineering attacks that might leverage this vulnerability. Additionally, system administrators should monitor for unauthorized access attempts and ensure proper access controls are in place to limit local attack surface exposure. The vulnerability serves as a reminder of the importance of following secure coding practices and implementing proper memory management techniques to prevent buffer overflow conditions that can lead to system instability and potential security breaches.
