A stack overflow vulnerability exists in the WebCam Server Login functionality of GeoVision GV-VMS V20 20.0.2. A specially crafted HTTP request can lead to an arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger this vulnerability. #### Stack-overflow via unconstrained sscanf The call to `sscanf` at [1] to split the `Buffer` variable into the `username` and `password` variables doesn't limit the size of the extracted content to match the destination buffers' sizes. In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur. The data is controlled by an attacker, but sronger constraints (e.g. no null bytes) may make exploitation harder. A successful attack could lead to full code execution as SYSTEM on the machine running the service.
Casky was already ahead
This CVE exploits attack patterns that Casky's 255matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-7372 is a critical stack overflow vulnerability in GeoVision GV-VMS V20 20.0.2's WebCam Server login functionality, stemming from improper use of sscanf() that fails to constrain input size against destination buffer limits. An unauthenticated attacker can exploit this via a specially crafted HTTP request to achieve arbitrary code execution on the target system. This vulnerability is particularly dangerous because it requires no authentication and affects widely-deployed video management systems used in surveillance infrastructure across enterprises, government agencies, educational institutions, and critical infrastructure facilities. Organizations running GeoVision GV-VMS V20 20.0.2 face immediate risk of complete system compromise, lateral movement, and data theft.
Casky's 255 matching security skills, powered by Claude AI with extended reasoning, detect the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0002 (Execution) and TA0003 (Persistence). Practitioners using Casky would identify reconnaissance indicators when attackers probe the WebCam Server login endpoint, followed by exploitation attempts through malformed HTTP requests containing oversized payload fields designed to overflow stack buffers. The platform's skills enable detection of memory corruption signatures, abnormal process behavior post-exploitation, code injection patterns, and suspicious network activity indicative of command execution or reverse shell establishment. By correlating these technique-specific indicators with the CWE-787 (Out-of-bounds Write) pattern, Casky helps security teams distinguish legitimate failed login attempts from active exploitation attempts and respond before arbitrary code execution occurs.
