CVE-2019-25362
Published: 18 February 2026
Summary
CVE-2019-25362 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Alloksoft Wmv To Avi Mpeg Dvd Wmv Convertor. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 46.5th 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-2019-25362 is a stack-based buffer overflow vulnerability (CWE-787) affecting WMV to AVI MPEG DVD WMV Convertor version 4.6.1217. The issue resides in the application's input handling for the license name and license code fields, where insufficient bounds checking allows overflow conditions that enable arbitrary code execution.
An unauthenticated attacker can exploit this remotely with low complexity and no user interaction, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). By crafting a malicious payload of 6000 bytes, the attacker can overwrite the stack to execute arbitrary code, such as triggering a bind shell on port 4444, resulting in high confidentiality, integrity, and availability impacts on the affected system.
Public proof-of-concept exploits are documented on Exploit-DB (exploits 47563 and 47568), and a vulnerability advisory is available from Vulncheck. The vendor site at Alloksoft provides the product page but does not detail patches or specific mitigations in the referenced information.
