How the Exploit Works
The heap-based buffer overflow vulnerability is present in the RHS2000 parsing functionality of The Biosig Project libbiosig. An attacker can craft a malicious RHS2000 file that, when processed by the software, overflows the buffer’s boundaries and allows the attacker to write and execute arbitrary code. This arbitrary code execution could lead to a full system compromise or data leakage, depending on the privileges of the software process on the system.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. In this case, a malicious payload is sent in the form of a specially crafted RHS2000 file.
$ echo -n "malicious_payload" > exploit.rhs2000
$ curl -X POST -H "Content-Type: application/rhs2000" --data-binary @exploit.rhs2000 http://target.example.com/vulnerable/endpointIn this example, “malicious_payload” would be replaced with the actual malicious code that exploits the buffer overflow. When the target system processes this file through the vulnerable endpoint, it triggers the overflow and executes the attacker’s code.
