A vulnerability was found in PHPGurukul Online Course Registration up to version 3.1. This issue affects some unknown processing of the file /admin/edit-student-profile.php of the component Student Registration Page. The manipulation of the argument photo results in unrestricted upload. The attack may be launched remotely. The exploit has been made public and could be used.
The severity level of this vulnerability is classified as low, with a CVSS score of 2.1 according to CVSS 4.0 metrics. However, organizations should be aware that the exploitation could lead to unauthorized access or manipulation of uploaded files. This presents a risk to organizations, especially if sensitive information is stored or processed through the application.
Given the vulnerability's nature and the potential for exploitation, organizations using PHPGurukul Online Course Registration should prioritize patching immediately. While the CVSS score indicates a low severity, the risk context highlights the importance of remediation to prevent potential attacks.
Currently, the vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog, suggesting it hasn't been widely exploited in the wild. However, with a public exploit available, vigilance is recommended.
Vulnerability Details
The vulnerability allows unrestricted file uploads due to improper handling of the photo argument in the /admin/edit-student-profile.php file. The CVSS 4.0 vector for this vulnerability shows it as having a network attack vector with low complexity, requiring low privileges and no user interaction.
The affected product is the PHPGurukul Online Course Registration system, which must be updated to the latest version to mitigate this risk. The CWE classifications applicable to this vulnerability include CWE-284 (Improper Access Control) and CWE-434 (Unrestricted File Upload).
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of user-uploaded files. Attackers may exploit this vulnerability to upload malicious files, potentially leading to further exploitation of the system. The attack vector is primarily network-based, and the complexity is low, allowing attackers to initiate it remotely without requiring significant technical skill.
The attack requires low privileges, indicating that even users with limited access can potentially exploit this vulnerability. No user interaction is necessary, making it easier for attackers to execute. The confidentiality, integrity, and availability impacts are all rated as low, indicating that while the potential for damage exists, it may not be as severe as higher-severity vulnerabilities.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data or system resources, which could lead to data breaches or system compromises. The unrestricted nature of file uploads could enable the execution of malicious scripts or the introduction of malware into the environment.
The urgency for remediation should be assessed against the operational context of the affected systems. Organizations should address this vulnerability in their priority patch cycle, as even low-severity vulnerabilities can lead to significant impacts if exploited.
