CVE-2017-7272
CVSS v2.0
7.8
High
| Vector | AV:N/AC:M/Au:N/C:P/I:C/A:N |
Name of the Vulnerable Software and Affected Versions
PHP versions prior to 7.1.12
Description
The issue is related to insufficient validation of incoming requests, which can be exploited by a remote attacker to access and compromise confidential data. In applications that use
fsockopen or pfsockopen with a hostname argument, the :port syntax can be used to specify a port number in the hostname, potentially bypassing expected port constraints.Recommendations
For PHP versions prior to 7.1.12, consider updating to a version that includes the necessary security fixes to prevent potential SSRF attacks. As a temporary workaround, restrict the use of
fsockopen and pfsockopen functions with user-provided hostname arguments to minimize the risk of exploitation. Additionally, ensure that all incoming requests are thoroughly validated to prevent unauthorized access to sensitive data.Fix
