AlienVault OTX Vulnerabilities

AlienVault OTX Malware

libbiosig

A double-free vulnerability exists in the BrainVision ASCII Header Parsing functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .vdhr file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

CVE-2024-23809 is a critical security vulnerability identified in The Biosig Project's libbiosig library, specifically in the BrainVision ASCII Header Parsing component. The vulnerability is classified as a double-free (CWE-415), which occurs when the software attempts to free the same memory location twice, leading to undefined behavior such as memory corruption. In this case, the flaw is triggered by processing a specially crafted .vdhr file, a format used for storing biosignal header data. Exploiting this vulnerability allows an attacker to execute arbitrary code remotely without any authentication or user interaction, as the library processes input files. The vulnerability affects libbiosig version 2.5.0 and the Master Branch (ab0ee111). The CVSS v3.1 base score of 9.8 indicates a critical severity, with attack vector Network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high, meaning a successful exploit could lead to full system compromise. While no public exploits have been reported yet, the nature of the vulnerability and its critical rating suggest that exploitation could be straightforward once a malicious .vdhr file is delivered to a vulnerable system. The Biosig Project is widely used in biomedical research and clinical environments for biosignal data acquisition and analysis, making this vulnerability particularly relevant to organizations handling sensitive medical data.
