This vulnerability allows a local attacker to execute arbitrary code on a vulnerable system. The attack involves crafting a malicious string and supplying it to the \u0026ldquo;License Name\u0026rdquo; field of the application during registration. Exploitation occurs due to the application\u0026rsquo;s failure to properly validate the length of the input, allowing a buffer overflow to occur. The attacker leverages Structured Exception Handler (SEH) overwrite and injects shellcode to gain code execution in the context of the application. This vulnerability was reported in April 2026.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains local access to a system with Alloksoft Video Joiner 4.6.1217 installed.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies the \u0026ldquo;License Name\u0026rdquo; field within the application\u0026rsquo;s registration process as a potential vulnerability point.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious string that exceeds the expected buffer size for the \u0026ldquo;License Name\u0026rdquo; field.\u003c/li\u003e\n\u003cli\u003eThe malicious string includes an SEH overwrite payload, redirecting execution flow to the attacker\u0026rsquo;s controlled memory.\u003c/li\u003e\n\u003cli\u003eThe crafted string also contains shellcode designed to perform arbitrary code execution.\u003c/li\u003e\n\u003cli\u003eThe attacker inputs the malicious string into the \u0026ldquo;License Name\u0026rdquo; field and submits the registration form.\u003c/li\u003e\n\u003cli\u003eThe application attempts to process the oversized string, triggering a buffer overflow.\u003c/li\u003e\n\u003cli\u003eThe SEH overwrite redirects execution to the injected shellcode, granting the attacker arbitrary code execution within the context of the Alloksoft Video Joiner process.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this buffer overflow vulnerability allows a local attacker to execute arbitrary code with the privileges of the Alloksoft Video Joiner application.
