This vulnerability allows a local attacker to execute arbitrary code on a targeted system. The attack vector involves supplying an overly long string to the “License Name” field of the application, triggering the buffer overflow. Successful exploitation allows attackers to inject and execute shellcode within the context of the application, potentially leading to privilege escalation and complete system compromise. This vulnerability was reported in April 2026.

Attack Chain

1. Attacker crafts a malicious input string containing shellcode.
2. The malicious string is designed to overwrite the Structured Exception Handler (SEH).
3. Attacker opens Allok Soft WMV to AVI MPEG DVD WMV Converter 4.6.1217.
4. Attacker inputs the crafted string into the “License Name” field within the application’s interface.
5. The application attempts to process the oversized input, triggering a buffer overflow.
6. The overflow overwrites the SEH with a pointer to the attacker-controlled shellcode.
7. An exception is triggered within the application.
8. The SEH handler is invoked, redirecting execution flow to the injected shellcode, enabling arbitrary code execution.

Impact

Successful exploitation of CVE-2018-25314 allows a local attacker to execute arbitrary code with the privileges of the Allok Soft WMV to AVI MPEG DVD WMV Converter application. This could lead to sensitive data theft, installation of malware, or complete system compromise. While specific victim counts are unavailable, any system running the vulnerable software is at risk.

Recommendation

• Monitor process creations for wmvconverter.exe spawning unusual child processes using the Alloksoft WMV Converter Spawning Suspicious Process Sigma rule.
• Monitor for unexpected registry modifications performed by wmvconverter.exe using the Alloksoft WMV Converter Registry Modification Sigma rule.
• Consider removing Allok Soft WMV to AVI MPEG DVD WMV Converter 4.6.1217 from systems where it is not essential, as no patch is available.

This vulnerability enables a local attacker to execute arbitrary code by crafting a specific payload. The attack involves providing a malicious string in the License Name field of the application. This can be exploited without requiring any prior authentication, making it a significant security concern for systems running the vulnerable software. The vulnerability was reported on April 29, 2026.

Attack Chain

1. The attacker prepares a malicious string payload consisting of junk data, an NSEH bypass, an SEH handler address, and shellcode.
2. The attacker opens the Allok AVI to DVD SVCD VCD Converter application.
3. The attacker navigates to the registration or license activation section of the software.
4. The attacker pastes the malicious string into the License Name field.
5. The attacker clicks the “Register” button, triggering the buffer overflow.
6. The overflow overwrites the SEH frame, redirecting execution flow to the attacker-controlled NSEH bypass.
7. The NSEH bypass redirects execution to the SEH handler address, which points to the attacker’s shellcode.
8. The shellcode executes, allowing the attacker to run arbitrary code on the system.

Impact

Successful exploitation of this buffer overflow vulnerability allows a local attacker to execute arbitrary code with the privileges of the user running the Allok AVI to DVD SVCD VCD Converter. This could lead to complete system compromise, data theft, or installation of malware. Given the ease of exploitation (no authentication required, local access only) this poses a significant risk to systems with the vulnerable software installed.

Recommendation

• Deploy the Sigma rule Allok AVI Converter SEH Buffer Overflow to detect exploitation attempts based on process creation events.
• Monitor for abnormal process execution originating from the Allok AVI to DVD SVCD VCD Converter application to identify potential exploitation (process_creation).
• Consider removing the Allok AVI to DVD SVCD VCD Converter 4.0.1217 until a patch is available, due to the high severity and ease of exploitation.
