Descriptions du CVE

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.

CWE-ID Nom de la faiblesse Source
CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

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.

Percentile EPSS

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/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.
