A vulnerability was found in Linux Kernel (Operating System). It has been rated as problematic. Affected by this issue is some unknown functionality of the component UDP Handler. The manipulation with an unknown input leads to a information disclosure vulnerability (Fingerprint). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:
The UDP implementation in Linux 2.4.x kernels keeps the IP Identification field at 0 for all non-fragmented packets, which could allow remote attackers to determine that a target system is running Linux.
The weakness was released 08/12/2002 by Ofir Arkin with @stake (Website). The advisory is available at securityfocus.com. This vulnerability is handled as CVE-2002-0510. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.
The vulnerability scanner Nessus provides a plugin with the ID 17841 (Linux Kernel UDP Implementation IP Identification Field Remote OS Disclosure), which helps to determine the existence of the flaw in a target environment. It is assigned to the family General and running in the context r.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 30475.
