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.

In order to trigger the flaw, send a HTTP GET request similar to: https://<ip>/tmui/Control/jspmap/tmui/system/archive/properties.jsp?&name=../../../../../etc/passwd Condition: If file does not exist the application will return "File not found." If the file exists, the user can either send, a similar to, the next HTTP POST request or simply click on the Delete button through the GUI -the button will be displayed only if the enumerated file exists-.
