CVE-2018-25216 in AnyBurn
Summary
by MITRE • 03/26/2026
AnyBurn 4.3 contains a local buffer overflow vulnerability that allows local attackers to crash the application by supplying an excessively long string in the image file name field. Attackers can paste a 10000-byte payload into the 'Image file name' parameter during the 'Copy disk to Image' operation to trigger a denial of service condition.

The vulnerability identified as CVE-2018-25216 represents a critical local buffer overflow flaw within AnyBurn version 4.3 that fundamentally compromises application stability and integrity. This issue resides in the software's handling of user-supplied input during the disk image creation process, specifically when processing the 'Image file name' parameter. The flaw demonstrates a classic buffer overflow condition where insufficient input validation allows attackers to exceed allocated memory boundaries, resulting in unpredictable application behavior and system instability.
The technical implementation of this vulnerability stems from inadequate bounds checking within the application's string processing functions. When users attempt to copy a disk to an image file, the software fails to properly validate or limit the length of the image file name input field. This oversight creates an exploitable condition where attackers can craft malicious input sequences exceeding the allocated buffer space, typically triggering memory corruption that leads to application termination. The specific trigger involves pasting a 10000-byte payload into the designated parameter, which far exceeds normal usage patterns and exposes the underlying memory management weakness.
From an operational perspective, this vulnerability presents a significant denial of service threat to systems running AnyBurn 4.3, as local attackers can reliably crash the application without requiring elevated privileges. The impact extends beyond simple application instability, potentially disrupting legitimate workflow processes that depend on disk imaging capabilities. The vulnerability's local nature means it does not require network connectivity or remote access, making it particularly concerning for environments where such software is frequently used for backup operations or system recovery tasks. This condition effectively renders the application unusable until manual restart or system reboot occurs.
The vulnerability aligns with CWE-121, which categorizes buffer overflow conditions as critical weaknesses in memory safety, and demonstrates characteristics consistent with ATT&CK technique T1499.004 for denial of service through resource exhaustion. Security practitioners should note that this issue represents a fundamental flaw in input validation that could potentially be extended to more sophisticated attacks if additional vulnerabilities exist within the same codebase. The attack vector's simplicity and reliability make it particularly dangerous in environments where AnyBurn is used regularly, as it can be exploited repeatedly without detection. Organizations should prioritize immediate patching or mitigation strategies to prevent exploitation, as the vulnerability directly impacts the software's core functionality and operational continuity.
