CVE Descriptions

Multiple directory traversal vulnerabilities in PHP 5.2.6 and earlier allow context-dependent attackers to bypass safe_mode restrictions by creating a subdirectory named http: and then placing ../ (dot dot slash) sequences in an http URL argument to the (1) chdir or (2) ftok function.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

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.

source: https://www.securityfocus.com/bid/29796/info PHP is prone to multiple 'safe_mode' restriction-bypass vulnerabilities. Successful exploits could allow an attacker to determine the presence of files in unauthorized locations; other attacks are also possible. Exploiting these issues allows attackers to obtain sensitive data that could be used in other attacks. These vulnerabilities would be an issue in shared-hosting configurations where multiple users can create and execute arbitrary PHP script code; in such cases, the 'safe_mode' restriction is expected to isolate users from each other. PHP 5.2.6 is vulnerable; other versions may also be affected. cxib# cat /www/wufff.php <? echo getcwd()."\n"; chdir("/etc/"); echo getcwd()."\n"; ?> cxib# ls -la /www/wufff.php -rw-r--r-- 1 www www 62 Jun 17 17:14 /www/wufff.php cxib# php /www/wufff.php /www Warning: chdir(): SAFE MODE Restriction in effect.
