CVE Descriptions

Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.

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.

Exploit information

Exploit Database EDB-ID : 33988

Publication date : 2010-05-13 22h00 +00:00
Author : Stefan Esser
EDB Verified : Yes

source: https://www.securityfocus.com/bid/40173/info PHP is prone to multiple format-string vulnerabilities because it fails to properly sanitize user-supplied input before passing it as the format specifier to a formatted-printing function. Attackers can exploit these issues to run arbitrary code within the context of the PHP process. This may allow them to bypass intended security restrictions or gain elevated privileges. PHP 5.3 through 5.3.2 are vulnerable. $ php -r "fopen('phar:///usr/bin/phar.phar/*%08x-%08x-%08x-%08x-%08x-%08x-%08x-%08x-%08x','r');"
