Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Serilog.Enrichers.ClientInfo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Serilog (before v2.1.0) contains a Client IP Spoofing vulnerability, which allows attackers to falsify their IP addresses in log files by specifying an arbitrary IP as a value of X-Forwarded-For or Client-Ip headers while performing HTTP requests. It is not possible to configure Serilog.Enrichers.ClientInfo to not trust the X-Forwarded-For header.
