CVE-2022-37028 is a stored Cross-site Scripting (XSS) vulnerability identified in ISAMS version 22.2.3.2. The vulnerability specifically affects the title field for groups within the application. An attacker can exploit this flaw by injecting malicious JavaScript code into the title field, which is then stored persistently on the server. When other users access the affected group title field in the application, the malicious script executes in their browsers under the context of the vulnerable application. This type of stored XSS attack can lead to session hijacking, unauthorized actions on behalf of users, theft of sensitive information, or the delivery of further malware payloads. The CVSS v3.1 base score for this vulnerability is 5.4, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) reveals that the attack can be performed remotely over the network with low attack complexity, requires the attacker to have some privileges (PR:L), and requires user interaction (UI:R) to trigger the payload. The vulnerability impacts confidentiality and integrity but does not affect availability. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. No public exploits are currently known in the wild, and no patches or vendor details were provided in the source information. The vulnerability is classified under CWE-79, which corresponds to improper neutralization of input during web page generation leading to XSS.

For European organizations using ISAMS 22.2.3.2, this vulnerability poses a risk of unauthorized script execution within the context of the application. ISAMS is a widely used school management information system, so educational institutions are primarily at risk. Exploitation could allow attackers to hijack user sessions, steal sensitive student or staff data, manipulate application data, or conduct phishing attacks by injecting deceptive content. This can lead to data breaches, reputational damage, and regulatory non-compliance under GDPR due to exposure of personal data. The requirement for some level of privilege to inject the payload limits the attack surface but does not eliminate risk, especially if insider threats or compromised accounts exist. The need for user interaction to trigger the payload means social engineering or tricking users into viewing the malicious content is necessary. The changed scope indicates that the impact could extend beyond the immediate vulnerable component, potentially affecting other parts of the application or connected systems. Given the critical role of ISAMS in managing sensitive educational data, the impact on confidentiality and integrity is significant for European educational organizations.

1. Immediate mitigation should involve restricting privileges to only trusted users who can edit group titles to reduce the risk of malicious input. 2. Implement input validation and output encoding specifically for the title field to neutralize any embedded scripts before storage and rendering. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the application context. 4. Educate users about the risks of clicking on suspicious links or interacting with unexpected content within the application to reduce successful exploitation via social engineering. 5. Monitor application logs for unusual input patterns or attempts to inject scripts in group titles. 6. Engage with the ISAMS vendor or community to obtain official patches or updates addressing this vulnerability. 7. If patches are unavailable, consider temporary workarounds such as disabling the group title editing feature or sanitizing data at the database level. 8. Conduct regular security assessments and penetration testing focusing on input handling and XSS vectors within the application. These steps go beyond generic advice by focusing on privilege management, specific input sanitization, and user awareness tailored to the context of ISAMS and the nature of this stored XSS vulnerability.
