| Weakness Name | Source | |
|---|---|---|
| Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |

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.

Tested on Windows XP Professional SP2 all patched, with Internet Explorer 7
<b>Description:
Using the "Load()" method we can load the content of a file from local machine passed as argument to
this function and then save it into arbitrary location with the "SaveAs()" method.
This allow to overwrite well known files with arbitrary data. I try to pass to the "Load()" method
remote directories (http) but, unfortunately, it accepts only local directories.</b>
