CVE-2022-42198: n/a in n/a
In Simple Exam Reviewer Management System v1.0 the User List function suffers from insecure file upload.
AI Analysis
Technical Summary
CVE-2022-42198 is a high-severity vulnerability identified in the Simple Exam Reviewer Management System version 1.0. The vulnerability arises from an insecure file upload mechanism within the User List function. Specifically, this vulnerability is categorized under CWE-434, which refers to 'Unrestricted Upload of File with Dangerous Type.' This means that the application does not properly validate or restrict the types of files that can be uploaded, allowing an attacker with at least low privileges (PR:L) to upload malicious files remotely (AV:N) without requiring any user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the system, indicating that successful exploitation could lead to full compromise, including data theft, system manipulation, or denial of service. The CVSS 3.1 base score of 8.8 reflects the critical nature of this vulnerability. Although no known exploits are currently reported in the wild, the ease of exploitation combined with the potential impact makes this a significant threat. The lack of vendor or product-specific information limits detailed contextual analysis, but the vulnerability's nature suggests that attackers could upload web shells or other malicious payloads to execute arbitrary code on the server, potentially leading to complete system takeover. This vulnerability is particularly concerning in environments where the Simple Exam Reviewer Management System is used to manage sensitive educational data or user information.
Potential Impact
For European organizations, the impact of this vulnerability could be severe, especially for educational institutions or service providers using the Simple Exam Reviewer Management System. Exploitation could lead to unauthorized access to sensitive student data, exam materials, and personal information, violating GDPR and other data protection regulations. The compromise of system integrity could disrupt examination processes, leading to operational downtime and reputational damage. Additionally, attackers could leverage the vulnerability to pivot within the network, potentially accessing other critical systems. The high confidentiality, integrity, and availability impact means that organizations could face significant financial penalties, legal consequences, and loss of trust from stakeholders. Given the remote exploitability without user interaction, the threat could be exploited at scale if the system is exposed to the internet or insufficiently segmented within internal networks.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately restrict or disable the file upload functionality in the User List feature until a secure patch or update is available. 2) Implement strict server-side validation of uploaded files, including checking MIME types, file extensions, and scanning for malicious content. 3) Employ allowlisting of file types and reject all others by default. 4) Use sandboxing or isolated environments for handling uploaded files to prevent execution of malicious code. 5) Monitor logs for unusual upload activity and implement intrusion detection systems to detect exploitation attempts. 6) Apply network segmentation to limit access to the affected system and reduce lateral movement risk. 7) Regularly back up critical data and verify the integrity of backups to enable recovery in case of compromise. 8) Engage with the software vendor or community to obtain patches or updates addressing this vulnerability. 9) Conduct security awareness training for administrators managing the system to recognize and respond to suspicious activities. These measures go beyond generic advice by focusing on immediate containment, validation controls, and proactive monitoring tailored to the specific vulnerability.
