AlienVault OTX Vulnerabilities

AlienVault OTX Malware

An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.

CVE-2023-39191 is a vulnerability identified in the eBPF (extended Berkeley Packet Filter) subsystem of the Linux kernel, specifically impacting Red Hat Enterprise Linux 9. The flaw arises from improper input validation of dynamic pointers within user-supplied eBPF programs before their execution. eBPF programs allow for running sandboxed code in the kernel space, often used for performance monitoring, networking, and security purposes. The vulnerability allows an attacker possessing CAP_BPF privileges—a capability that grants permission to load and manipulate eBPF programs—to exploit the lack of validation to escalate privileges and execute arbitrary code within the kernel context. This could lead to full system compromise, as kernel-level code execution bypasses all user-space security controls. The CVSS 3.1 base score is 8.2, indicating high severity, with vector AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H. This means the attack requires local access with low complexity, high privileges, no user interaction, and impacts confidentiality, integrity, and availability with scope change. Although no known exploits are currently reported in the wild, the potential impact is significant due to the kernel-level execution. The vulnerability affects Red Hat Enterprise Linux 9, a widely used enterprise Linux distribution, especially in server and cloud environments. The lack of proper validation of dynamic pointers in eBPF programs is a critical oversight given the sensitive nature of kernel operations and the power of eBPF to influence system behavior.
