CVE-2024-31760 is a vulnerability identified in the sanluan flipped-aurora gin-vue-admin version 2.4.x, a web administration framework built on Vue.js and Go. The vulnerability stems from improper authorization checks in the Session Expiration component, classified under CWE-266 (Improper Authorization). This flaw allows an attacker who already has some level of privileges (PR:H) to escalate their privileges further without requiring any user interaction (UI:N). The attack vector is network-based (AV:N), meaning the attacker can exploit the vulnerability remotely over the network. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L) because the attacker can gain higher privileges, potentially accessing or modifying sensitive data or disrupting services. The CVSS 3.1 base score is 4.7, reflecting a medium severity level. No known exploits have been reported in the wild, and no patches have been released at the time of publication. The vulnerability is significant for environments where gin-vue-admin 2.4.x is deployed, especially in administrative contexts where privilege escalation can lead to critical security breaches. The lack of user interaction requirement facilitates automated exploitation once an attacker has initial access. The vulnerability highlights the importance of robust session management and authorization controls in web administration frameworks.

The primary impact of CVE-2024-31760 is the unauthorized escalation of privileges within affected gin-vue-admin 2.4.x deployments. This can lead to attackers gaining administrative or higher-level access beyond their intended permissions, compromising the confidentiality and integrity of sensitive data managed through the admin interface. Additionally, attackers could disrupt availability by modifying or deleting critical configurations or data. Organizations relying on this framework for internal or external administrative portals face increased risk of insider threats or lateral movement by attackers who have obtained limited access. Although no exploits are currently known in the wild, the vulnerability could be leveraged in targeted attacks against organizations using this software, especially if combined with other vulnerabilities or weak authentication mechanisms. The medium severity rating indicates moderate risk, but the potential for privilege escalation in administrative contexts makes it a significant concern for organizations with sensitive or critical infrastructure managed via gin-vue-admin.

To mitigate CVE-2024-31760, organizations should first identify all instances of sanluan flipped-aurora gin-vue-admin 2.4.x in their environment. Until an official patch is released, implement strict access controls to limit who can authenticate and access the administration interface, ideally restricting it to trusted networks or VPNs. Employ multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit the vulnerability. Monitor logs and audit trails for unusual privilege escalation attempts or suspicious session behaviors. Consider deploying web application firewalls (WAFs) with custom rules to detect and block anomalous requests targeting session management endpoints. Review and harden session expiration and authorization logic in custom deployments or forks of the software. Once a patch becomes available, prioritize its deployment in all affected environments. Additionally, conduct regular security assessments and penetration testing focused on privilege escalation vectors within administrative interfaces.
