CVE-2022-25481 is a high-severity vulnerability affecting ThinkPHP Framework v5.0.24. This vulnerability allows attackers to access all system environment parameters through misconfiguration, specifically the absence of the PATHINFO parameter in the index.php file. The potential for system exposure is significant, as it could lead to unauthorized access to sensitive information.
With a CVSS score of 7.5, this vulnerability is classified as high severity, indicating substantial risk to organizations utilizing the affected version of the ThinkPHP Framework. The exploitation status is currently unknown, as there are no confirmed public exploits or proofs of concept available.
Organizations using this version of ThinkPHP are encouraged to prioritize patching to mitigate the risks associated with this vulnerability. The urgency for defenders is high due to the potential exposure of system parameters, which could lead to further attacks or data breaches.
Immediate actions should be taken to review configurations and ensure that the PATHINFO parameter is properly set to prevent unauthorized access to sensitive system information.
Vulnerability Details
The vulnerability in question allows unauthorized access to environment parameters configured within the ThinkPHP Framework. It is attributed to a misconfiguration that exposes sensitive information.
As defined by the CVSS 3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the attack vector is categorized as network, with low attack complexity. No privileges are required for exploitation, and user interaction is not necessary. The confidentiality impact is rated as high, while integrity and availability impacts are rated as none.
The vulnerability was published on March 21, 2022, and has since been marked as modified in the vulnerability database. The associated CWE identifiers are CWE-668 and CWE-284.
Technical Analysis
The root cause of this vulnerability lies in the misconfiguration of the ThinkPHP Framework, specifically the lack of the PATHINFO parameter, which is intended to control access to environment variables.
The attack vector is network-based, allowing potential remote exploitation without requiring physical access to the system. The attack complexity is low, indicating that relatively simple methods could be employed for exploitation. No privileges are required, and user interaction is not necessary, making this vulnerability particularly concerning.
The vulnerability impacts confidentiality significantly, as attackers may gain access to sensitive system parameters which could be exploited for further attacks. However, integrity and availability are unaffected.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information, which could lead to data breaches and exploitation of further vulnerabilities. The blast radius is significant, as a compromised environment could affect not only the immediate system but potentially other connected systems.
Given the CVSS score of 7.5, organizations should assess the urgency of their remediation efforts. The EPSS score of 0.095 indicates a percentile rank of 0.928, suggesting a relatively high likelihood of exploitation in the wild.
Organizations should prioritize patching immediately to mitigate this high-severity vulnerability and prevent potential exploitation.

Affected Versions
The affected version of the ThinkPHP Framework is v5.0.24. Organizations using this version should take immediate action to remediate this vulnerability, as all versions prior to vendor patch are at risk.
Mitigation & Remediation
Organizations should prioritize patching to the latest version of the ThinkPHP Framework to remediate this vulnerability. If a patch is not yet available, configuration hardening should be performed to ensure the PATHINFO parameter is properly set.
Additionally, organizations may consider implementing network controls to restrict access to the application and monitoring solutions to detect any unauthorized access attempts.
Security testing can also be employed to validate the security posture of the application and identify any additional vulnerabilities.
Detection Guidance
It is recommended to monitor logs for indicators of unauthorized access attempts or unusual behavior that may suggest exploitation of this vulnerability.
Behavioral anomalies, such as unexpected access to environment parameters, should be investigated promptly to assess potential breaches.
