Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
Multiple cross-site request forgery (CSRF) vulnerabilities in TRENDnet TEW-812DRU router with firmware before 1.0.9.0 allow remote attackers to hijack the authentication of administrators for requests that (1) change admin credentials in a request to setSysAdm.cgi, (2) enable remote management or (3) enable port forwarding in an Apply action to uapply.cgi, or (4) have unspecified impact via a request to setNTP.cgi. NOTE: some of these details are obtained from third party information.
CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| Cross-Site Request Forgery (CSRF) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. |
Metrics
| Metrics | Score | Severity | CVSS Vector | Source |

| V2 | 6.8 | AV:N/AC:M/Au:N/C:P/I:P/A:P | nvd@nist.gov |
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.
