CVE-2018-25383 in Free MP3 CD Ripper
Summary
by MITRE • 05/29/2026
Free MP3 CD Ripper 2.8 contains a stack-based buffer overflow vulnerability in WMA file processing that allows local attackers to bypass DEP protection via structured exception handling manipulation. Attackers can craft a malicious WMA file that triggers the overflow when loaded through the Convert function, enabling execution of arbitrary code through ROP chain gadgets and shellcode injection.

The vulnerability under analysis involves a stack-based buffer overflow present in Free MP3 CD Ripper version 2.8 specifically during the processing of WMA files. This flaw resides within the application's structured handling of multimedia file formats and represents a critical security weakness that can be exploited by local attackers to gain unauthorized code execution capabilities. The vulnerability manifests when the application's Convert function processes a maliciously crafted WMA file, triggering the buffer overflow condition that compromises the program's execution flow.
The technical implementation of this vulnerability stems from inadequate input validation and memory management practices within the WMA file parsing routine. When the application encounters a malformed WMA file containing oversized data structures or maliciously constructed metadata, the buffer overflow occurs in the stack memory region, allowing attackers to overwrite adjacent memory locations including return addresses and exception handling structures. This particular implementation leverages the application's structured exception handling mechanism as an exploitation vector, bypassing modern exploit mitigation techniques such as Data Execution Prevention. The attacker's ability to manipulate the structured exception handling framework enables the circumvention of DEP protection, which typically prevents execution of data segments in memory.
The operational impact of this vulnerability extends beyond simple code execution to enable sophisticated attack scenarios through the use of Return Oriented Programming (ROP) chains. Attackers can construct malicious WMA files that, when processed by the vulnerable application, trigger a series of gadget-based instructions embedded within the application's memory space or loaded libraries. These ROP chains allow for the construction of arbitrary code execution sequences without requiring direct shellcode injection into the process memory. The exploitation process typically begins with the buffer overflow corrupting the stack frame, followed by manipulation of the exception handling context to redirect execution flow through carefully selected memory addresses containing useful code snippets. This approach enables attackers to execute complex operations including privilege escalation, information disclosure, or system compromise without direct code injection into the application's memory space.
Security professionals should recognize this vulnerability as a variant of CWE-121, which describes stack-based buffer overflow conditions, and as part of the broader ATT&CK technique T1059.007 related to command and scripting interpreters. The exploitation pattern aligns with ATT&CK technique T1203 which covers exploitation for client execution, and T1068 which covers exploit for privilege escalation. Organizations should implement immediate mitigations including application whitelisting, patching the vulnerable software to the latest version, and deploying runtime application self-protection (RASP) mechanisms to detect and prevent such buffer overflow conditions. The vulnerability also highlights the importance of input validation and memory safety practices in multimedia processing applications, as similar issues have been documented in numerous audio and video processing libraries. Additionally, regular security assessments and penetration testing of multimedia applications are crucial to identify similar memory corruption vulnerabilities that could be exploited to bypass modern security protections including DEP, ASLR, and stack canaries.
