This vulnerability allows a local attacker to execute arbitrary code on a vulnerable system. The attack involves crafting a malicious payload containing shellcode and SEH overwrite values. The attacker then enters this payload into the \u0026ldquo;License Name\u0026rdquo; field within the application. Successful exploitation gives the attacker the ability to execute arbitrary code within the context of the application. This is a local vulnerability, requiring the attacker to have access to the system where the software is installed.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker crafts a text file containing a malicious payload.\u003c/li\u003e\n\u003cli\u003eThe payload includes shellcode designed to execute arbitrary commands.\u003c/li\u003e\n\u003cli\u003eThe payload also contains specific values to overwrite the Structured Exception Handler (SEH) chain.\u003c/li\u003e\n\u003cli\u003eAttacker copies the contents of the crafted text file.\u003c/li\u003e\n\u003cli\u003eAttacker opens Allok AVI DivX MPEG to DVD Converter 2.6.1217 on the target system.\u003c/li\u003e\n\u003cli\u003eAttacker pastes the malicious payload into the \u0026ldquo;License Name\u0026rdquo; field of the application.\u003c/li\u003e\n\u003cli\u003eThe application attempts to process the oversized or malformed license.\u003c/li\u003e\n\u003cli\u003eThe buffer overflow occurs, overwriting the SEH chain and executing the attacker-supplied shellcode, resulting in arbitrary code execution.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability (CVE-2018-25323) allows a local attacker to execute arbitrary code on the targeted system.
