CVE-2001-0500 : 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.

An unchecked buffer resides in the 'idq.dll' ISAPI extension associated with each service. A maliciously crafted request could allow arbitrary code to run on the host in the Local System context. Note that Index Server and Indexing Service do not need to be running for an attacker to exploit this issue. Since 'idq.dll' is installed by default when IIS is installed, IIS would need to be the only service running. Note also that this vulnerability is currently being exploited by the 'Code Red' worm.
