Published: 22 April 2026
Summary
CVE-2018-25260 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Magix Music Editor Deluxe. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 11.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2018-25260 is a buffer overflow vulnerability (CWE-787) in MAGIX Music Editor 3.1, specifically within the FreeDB Proxy Options dialog. The flaw enables local attackers to execute arbitrary code by exploiting structured exception handling (SEH). Attackers craft a malicious payload and paste it into the Server field, accessible via the CD menu's FreeDB Proxy Options, triggering execution upon accepting the settings. The vulnerability carries a CVSS v3.1 base score of 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Local attackers with access to the system can exploit this vulnerability due to its low attack complexity and lack of required privileges. By inducing the buffer overflow through the manipulated Server field, they achieve arbitrary code execution, potentially granting full control over the affected process and compromising confidentiality, integrity, and availability.
