VAR-200111-0009

Vulnerability from variot - Updated: 2025-04-03 22:30

Microsoft IIS 5.0 allows remote attackers to spoof web log entries via an HTTP request that includes hex-encoded newline or form-feed characters. A weakness in the reporting functionality of Microsoft IIS has been discovered. It is possible to cause IIS to log false information. This problem occurs when an attacker makes a HTTP request using hexadecimal encoded requests. A malicious attacker can cause IIS to fill the log with false information. This may result in confusion when other services make use of the false IIS log data. It should be noted that this issue highly depends on the text editor used to analyze the logs. Some hexadecimal sequences may have varying results when interpreted
