Original Post: CSV injection: how risky is it. In the last few months, I tested… | by Pranav Vedma | Sep, 2024
The content discusses the CSV injection vulnerability, which occurs when attackers inject malicious macros into data that gets exported to CSV or Excel files. The risk rating for such vulnerabilities depends on impact and likelihood. Impact is determined by potential outcomes of a successful exploit, like executing remote code or directing victims to malicious websites. Likelihood considers factors such as whether the data export function supports CSV or Excel formats, if the data can be user-controlled, and if the victim opens the file in an application that supports macros.
Typically, CSV injection vulnerabilities are deemed low-risk due to the necessary user interactions. However, the risk increases if the CSV files are automatically sent to victims without their awareness, making them more likely to open the files from trusted sources. The article concludes that while CSV injection vulnerabilities are often low-risk, they can pose significant threats if automation and user habits are exploited.
