In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, and 8.3.* before 8.3.12, erroneous parsing of multipart form data contained in an HTTP POST request could lead to legitimate data not being processed. This could lead to a malicious attacker controlling part of the submitted data, potentially resulting in erroneous application behavior. The CVSS score for this vulnerability is 3.1, indicating a low severity level.
Organizations using the affected PHP versions are at risk of data integrity issues. Although the CVSS score suggests a lower priority, the potential for application malfunction necessitates immediate attention. The vulnerability is classified under CWE-444, which highlights issues related to the improper handling of input data.
Currently, there are no known public exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) database. However, organizations should prioritize patching to mitigate potential risks associated with this vulnerability.
Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability allows for erroneous parsing of multipart form data in specific versions of PHP. The affected versions are 8.1.* prior to 8.1.30, 8.2.* prior to 8.2.24, and 8.3.* prior to 8.3.12. This issue arises when the application fails to process data correctly, leading to potential data manipulation by an attacker.
The CVSS score of 3.1 indicates a low severity level with a high attack complexity. Attackers require low privileges to exploit this vulnerability, and no user interaction is needed.
The vulnerability impacts PHP, with a CWE classification of CWE-444, indicating improper input validation. This vulnerability was published on October 8, 2024.
Technical Analysis
The root cause of this vulnerability lies in the erroneous parsing of multipart form data within the PHP application. The attack vector is network-based, requiring attackers to send specially crafted HTTP POST requests to the server hosting PHP applications.
The attack complexity is considered high due to the requirement for specific conditions to be met for the attack to succeed. Attackers do not need high privileges to exploit this vulnerability, and no user interaction is needed. Confidentiality impact is none, while integrity impact is low, indicating that the attacker may manipulate some data without affecting the confidentiality of the overall system.
The vulnerability does not impact availability, meaning that the application remains operational despite the presence of this issue.
Risk & Impact Analysis
The real-world deployment risk is moderate due to the potential for data manipulation and erroneous application behavior. Organizations relying on PHP for their applications should be aware of the implications of this vulnerability. If exploited, attackers could disrupt data integrity, leading to unreliable application performance.
Given the CVSS score of 3.1, organizations should address this vulnerability in their priority patch cycle. The potential blast radius is significant, especially for applications processing sensitive or critical data.
Organizations should monitor for any unusual application behaviors and prioritize patching to prevent possible exploitation.

Affected Versions
The affected versions of PHP are as follows: 8.1.* prior to 8.1.30, 8.2.* prior to 8.2.24, and 8.3.* prior to 8.3.12. Organizations should ensure that they upgrade to the latest versions to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to the latest stable versions of PHP. Specifically, they should upgrade to PHP 8.1.30, 8.2.24, or 8.3.12 or later. If immediate patching is not possible, consider implementing configuration hardening strategies to limit exposure to malformed multipart data.
Organizations should also employ monitoring solutions to detect abnormal application behavior and network traffic. Regular security assessments can help ensure that any vulnerabilities are identified and remediated promptly. For further guidance, organizations can refer to resources on penetration testing to evaluate the security posture of their applications.
Detection Guidance
Organizations should monitor logs for indicators of any unusual multipart data submissions. Behavioral anomalies, such as unexpected application responses or data processing failures, should be investigated. Network signatures that flag abnormal HTTP POST requests can also aid in detection, and system changes should be monitored closely for indicators of compromise.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2024-8925 lies in its demonstration of how input validation flaws can lead to application instability. Security teams should be aware of the trends associated with vulnerabilities in data processing and prioritize input validation mechanisms in their development lifecycle.
This vulnerability emphasizes the need for security awareness in development processes. Organizations should adopt best practices for secure coding and conduct regular security training for developers. For more information on best practices, organizations can refer to the secure configuration management and the importance of adhering to coding standards.
Organizations can also benefit from engaging in regular security assessments, such as those provided by application security assessments, to identify vulnerabilities before they can be exploited.
In conclusion, the implications of CVE-2024-8925 should not be underestimated. Organizations must ensure they are proactive in their vulnerability management efforts.
