Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-117: Improper Output Neutralization for Logs, where the product constructs a log message from external input, but it does not neutralize or incorrectly neutralizes special elements when the message is written to a log file. In Github.com/tinfoil factory/netfoil, 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

### Summary HTTPS RR data returned from the DoH server was not properly handled. Unverified APLN data (which could contain arbitrary byte sequences) was written directly to the log. It could also cause unnecessary memory usage. The single-byte response code was also written directly to the log.
