CVE-2024-57773 is a cross-site scripting (XSS) vulnerability identified in the openSelectManyUserPage?orgid interface of JFinalOA, an enterprise application framework. The vulnerability exists in versions prior to 2025.01.01 and allows attackers to inject and execute arbitrary web scripts or HTML content via a crafted payload. This occurs because the affected interface does not properly sanitize user-supplied input, leading to the execution of malicious scripts in the context of the victim's browser. The CVSS v3.1 score is 4.8 (medium), with an attack vector of network (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), and user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N). No public exploits are known, and no official patches have been linked yet. The vulnerability falls under CWE-79, a common XSS weakness. Given the requirement for high privileges and user interaction, exploitation is somewhat constrained but still poses a risk, especially in environments where users have elevated access and may be tricked into interacting with malicious content.

The primary impact of CVE-2024-57773 is the potential compromise of confidentiality and integrity within affected JFinalOA deployments. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users with high privileges, potentially leading to session hijacking, unauthorized data access, or manipulation of application data. While availability is not impacted, the breach of confidentiality and integrity could result in data leaks, unauthorized actions, and erosion of trust in the affected systems. Organizations relying on JFinalOA for internal or external applications may face increased risk of targeted attacks, especially if attackers can craft convincing payloads that induce user interaction. The requirement for high privileges and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate risk in environments with privileged users. The absence of known exploits in the wild provides a window for proactive mitigation. However, failure to address this vulnerability could lead to exploitation in targeted attacks, especially in sectors handling sensitive information or critical business processes.

1. Upgrade JFinalOA to version 2025.01.01 or later once the patch is officially released to address the vulnerability. 2. Until a patch is available, implement strict input validation and output encoding on the openSelectManyUserPage?orgid interface to neutralize malicious payloads. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4. Limit the number of users with high privileges and enforce the principle of least privilege to reduce the attack surface. 5. Educate privileged users about the risks of interacting with untrusted links or payloads to mitigate social engineering vectors. 6. Monitor web application logs and user activity for signs of suspicious behavior or attempted exploitation. 7. Employ web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting the affected interface. 8. Conduct regular security assessments and penetration testing focused on input validation and XSS vulnerabilities in JFinalOA deployments.
