CVE-2018-25383

Vulnerability

Free MP3 CD Ripper version 2.8 is vulnerable to a stack-based buffer overflow when processing WMA files via the Convert function [1][3]. The vulnerability resides in the WMA file parsing routine, where insufficient bounds checking allows an attacker to overwrite the stack, including the Structured Exception Handler (SEH) [1]. The software is available from the vendor's download page [2].

Exploitation

An attacker must craft a malicious WMA file and convince a local user to load it into Free MP3 CD Ripper by clicking the "Convert" button and selecting the file [1]. No authentication is required, but the attacker needs local access to the system or the ability to deliver the file (e.g., via email or download). The exploit uses a ROP chain to bypass Data Execution Prevention (DEP) and overwrite the SEH to gain control of execution flow [1][3]. The provided exploit code generates a file that triggers the overflow and executes arbitrary shellcode (e.g., calc.exe) [1].

Impact

Successful exploitation allows arbitrary code execution in the context of the current user [1][3]. The attacker can run commands, install malware, or access sensitive data. Since the application runs with user privileges, the impact is limited to the user's permissions, but could lead to full compromise of the user's data and system.

Mitigation

As of the available references, no official patch has been released for Free MP3 CD Ripper 2.8 [1][3]. The vendor (Cleanersoft Software) may no longer support the product. Users are advised to avoid using the software or to exercise extreme caution when opening WMA files from untrusted sources. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog as of the publication date.
