Related Weaknesses

CWE-ID Weakness Name Source
CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

This vulnerability exists in the latest Windows version of the application available. nginx on Windows is vulnerable to a remote source disclosure attack. - Technical Details - (Source Download) http://[ webserver IP][:port]index.html::$DATA Issue 2: (Remote DoS (w/ Memory Corruption)) - Description - nginx 0.8.36 (Windows) does not seem to handle encoded directory traversal attempts properly. The corrupted registers in the crash dump seem to be loaded with damaged path variables. - Technical Details - (Remote DoS) http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%c0.%c0./%c0.%c0./%20 http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%c0.%c0./%20 http://[ webserver IP][:port]/%c0.%c0./%c0.%c0./%20 These three attempts will overwrite memory registers with different parts of the internal path based on where they try and traverse to.
