CVE-2020-37161 Overview
CVE-2020-37161 is a stack-based buffer overflow vulnerability affecting Wedding Slideshow Studio version 1.36. This vulnerability allows attackers to execute arbitrary code by overwriting the registration name field with a malicious payload. The flaw can be exploited to trigger remote code execution, enabling attackers to run system commands on the affected system.
Critical Impact
Successful exploitation allows attackers to execute arbitrary code with the privileges of the user running the application, potentially leading to full system compromise.

Technical Details for CVE-2020-37161
Vulnerability Analysis
This vulnerability is classified as CWE-121 (Stack-based Buffer Overflow). The application fails to properly validate the length of user-supplied input in the registration name field before copying it to a fixed-size buffer on the stack. When an attacker provides input that exceeds the buffer's allocated size, the excess data overwrites adjacent memory on the stack, including the return address.
The local attack vector requires user interaction, as the victim must open a malicious file or input a crafted registration name. However, no special privileges are required to exploit this vulnerability. The successful exploitation results in high impact to confidentiality, integrity, and availability of the affected system.
Root Cause
The root cause of this vulnerability is improper bounds checking on user-controlled input in the registration name processing routine. The application uses unsafe string handling functions that do not verify the input length against the destination buffer size, allowing attackers to write beyond the allocated buffer boundaries.
Attack Vector
The attack requires local access to the target system and depends on user interaction to trigger the vulnerability. An attacker can craft a specially designed payload containing shellcode that, when processed by the registration name field, overwrites the stack's return address. This hijacks the program's execution flow to the attacker's injected code, enabling arbitrary command execution such as launching system applications or downloading additional malware.
The vulnerability has been documented with a proof-of-concept demonstrating the ability to execute system commands, including launching the Windows calculator as a demonstration of code execution capability.
Detection Methods for CVE-2020-37161
Indicators of Compromise
- Unusual crash reports or application instability in Wedding Slideshow Studio
- Presence of abnormally long strings in registration or configuration files
- Unexpected child processes spawned by the Wedding Slideshow Studio application
- System behavior indicating code execution (e.g., unexpected calculator or command prompt launches)
Detection Strategies
- Monitor for anomalous process creation events originating from Wedding Slideshow Studio
- Implement endpoint detection rules to identify stack buffer overflow exploitation patterns
- Use application whitelisting to prevent unauthorized code execution from vulnerable applications
Monitoring Recommendations
- Enable detailed application crash logging and analyze dump files for exploitation indicators
- Deploy endpoint detection and response (EDR) solutions to monitor for shellcode execution patterns
- Review process trees for unexpected child processes spawned by multimedia editing applications
How to Mitigate CVE-2020-37161
Immediate Actions Required
- Discontinue use of Wedding Slideshow Studio version 1.36 until a patched version is available
- Implement application whitelisting policies to restrict unauthorized code execution
- Educate users about the risks of opening untrusted files or entering suspicious registration data
- Deploy endpoint protection solutions capable of detecting buffer overflow exploitation attempts
Patch Information
No official patch information is currently available from the vendor. Users should monitor the Wedding Slideshow Studio Homepage for security updates. Additional technical details about this vulnerability are available in the VulnCheck Advisory and Exploit-DB #48050.
Workarounds
- Remove or disable Wedding Slideshow Studio from production systems until a patch is released
- Run the application in a sandboxed environment or virtual machine to contain potential exploitation
- Implement Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) at the operating system level to make exploitation more difficult
- Restrict access to the application to only trusted users who understand the associated risks
