Description
NSF Unidata NetCDF-C Variable Name Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NSF Unidata NetCDF-C. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of variable names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27267.

Executive Summary

This vulnerability is a stack-based buffer overflow in NSF Unidata NetCDF-C that occurs when parsing variable names. It happens because the software does not properly check the length of user-supplied data before copying it into a fixed-length buffer on the stack. An attacker can exploit this by tricking a user into visiting a malicious webpage or opening a malicious file, which then allows the attacker to execute arbitrary code with the same privileges as the current user. [1]

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the privileges of the current user. This can lead to unauthorized access, data modification, or disruption of services, impacting confidentiality, integrity, and availability of your system. [1]

Mitigation Strategies

To mitigate this vulnerability, avoid opening untrusted NetCDF files or visiting untrusted webpages that may trigger the vulnerability. Ensure that users are aware not to interact with suspicious files or links. Additionally, apply any available patches or updates from the vendor for NSF Unidata NetCDF-C to fix the buffer overflow issue. [1]
