CVE-2023-46817
CWE-502Published: November 3, 2023· Updated: Jun 17, 2026
Official Description
An issue was discovered in phpFox before 4.8.14. The url request parameter passed to the /core/redirect route is not properly sanitized before being used in a call to the unserialize() PHP function. This can be exploited by remote, unauthenticated attackers to inject arbitrary PHP objects into the application scope, allowing them to perform a variety of attacks, such as executing arbitrary PHP code.
Risk Analysis
phpFox is susceptible to PHP object injection via the url parameter, which can be leveraged by unauthenticated remote attackers to execute arbitrary code. The 9.8 CVSS score reflects the high severity of this remote code execution vulnerability.
No public exploit is known, and it is not in the KEV catalog.
Update phpFox to version 4.8.14 or later to ensure proper sanitization of input parameters.
Technical Analysis
CVE-2023-46817 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
