Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
Directory traversal vulnerability in index.php in PhpMyFaq 1.5.1 allows remote attackers to read arbitrary files or include arbitrary PHP files via a .. (dot dot) in the LANGCODE parameter, which also allows direct code injection via the User Agent field in a request packet, which can be activated by using LANGCODE to reference the user tracking data file.
CVE Informations
Metrics
| Metrics | Score | Severity | CVSS Vector | Source |
|---|---|---|---|---|
| V2 | 6.4 | AV:N/AC:L/Au:N/C:P/I:P/A:N | [email protected] |
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.
