Technical Analysis

CVE-2022-42197 is a vulnerability identified in the Simple Exam Reviewer Management System version 1.0. The core issue lies in the User List functionality, which suffers from improper access control. Specifically, this flaw allows users with low privileges to escalate their permissions by modifying user permissions to higher privilege levels without proper authorization checks. This vulnerability is categorized under CWE-425, which relates to improper authorization. The CVSS 3.1 base score for this vulnerability is 6.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N) reveals that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requiring the attacker to have some privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The vulnerability does not affect confidentiality or availability but has a high impact on integrity (I:H), as unauthorized privilege escalation can lead to unauthorized modifications within the system. No patches or known exploits in the wild have been reported as of the publication date. The lack of vendor or product details limits the ability to assess the broader ecosystem impact, but the vulnerability clearly enables privilege escalation within the application, which can be leveraged for further attacks or unauthorized access to sensitive data or administrative functions.

Potential Impact

For European organizations using the Simple Exam Reviewer Management System v1.0, this vulnerability poses a significant risk to the integrity of user permissions and overall system security. Unauthorized privilege escalation can lead to malicious insiders or external attackers gaining administrative control, potentially allowing them to alter exam data, user records, or system configurations. This could result in compromised exam integrity, data manipulation, and loss of trust in the system. Educational institutions and certification bodies relying on this system may face reputational damage, regulatory scrutiny, and operational disruptions. Given the medium CVSS score and the requirement for some level of initial access, the threat is more pronounced in environments where user accounts are shared or where low-privileged users have network access to the system. The absence of confidentiality and availability impacts reduces the risk of data leakage or denial of service but does not diminish the criticality of unauthorized privilege escalation in sensitive academic or certification contexts.

Mitigation Recommendations

To mitigate this vulnerability, organizations should implement strict access control mechanisms within the Simple Exam Reviewer Management System, ensuring that permission modifications are restricted to authorized administrative users only. Immediate steps include: 1) Conducting a thorough review of user roles and permissions to identify and restrict any unauthorized privilege changes. 2) Applying custom patches or configuration changes to enforce proper authorization checks on the User List function, if vendor patches are unavailable. 3) Implementing network segmentation and access controls to limit exposure of the management system to trusted users only. 4) Enhancing monitoring and logging of user permission changes to detect and respond to suspicious activities promptly. 5) Educating users about the risks of privilege escalation and enforcing strong authentication mechanisms to reduce the risk of compromised accounts. 6) Engaging with the vendor or community for updates or patches addressing this vulnerability. These measures should be prioritized to prevent exploitation and maintain the integrity of the system.
