Overview<\/strong><\/p>\n

In the continuous struggle to maintain information security, a new vulnerability, namely CVE-2025-48005, has been identified in The Biosig Project libbiosig 3.9.0 and Master Branch. This vulnerability has a severe impact on those systems running the said software, allowing attackers to execute arbitrary code, potentially compromising the system and leading to data leakage. It is crucial to address this issue promptly given its high severity score, to avoid any potential exploits<\/a> that could disrupt the integrity, availability, and confidentiality of the system.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-48005
\nSeverity: Critical (CVSS: 9.8)
\nAttack Vector: Local network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Arbitrary code execution, potential system<\/a> compromise, and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

The Biosig Project libbiosig<\/a> | 3.9.0, Master Branch (35a819fa)<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The heap-based buffer overflow vulnerability<\/a> 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<\/a>. This arbitrary code execution could lead to a full system<\/a> compromise or data leakage, depending on the privileges of the software process on the system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

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<\/a>.<\/p>\n

$ echo -n \"malicious_payload\" > exploit.rhs2000\n$ curl -X POST -H \"Content-Type: application\/rhs2000\" --data-binary @exploit.rhs2000 http:\/\/target.example.com\/vulnerable\/endpoint<\/code><\/pre>\n
In this example, “malicious_payload” would be replaced with the actual malicious code that exploits the buffer overflow<\/a>. When the target system processes this file through the vulnerable<\/a> endpoint, it triggers the overflow and executes the attacker’s code.<\/p>\n","protected":false},"excerpt":{"rendered":"
