Descriptions du CVE
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.

EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.
