CVE-2016-20045

HNB Organizer 1.9.18-10 contains a local buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized argument to the -rc command-line parameter. Attackers can craft a malicious input string exceeding 108 bytes containing shellcode and a return address to overwrite the stack and achieve code execution.
