RabidHamster R4 v1.25 contains a stack-based buffer overflow vulnerability due to unsafe use of sprintf() when logging malformed HTTP requests. A remote attacker can exploit this flaw by sending a specially crafted URI, resulting in arbitrary code execution under the context of the web server process.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
