An issue in trojan v.2.0.0 through v.2.15.3 allows a remote attacker to escalate privileges via the initialization interface /auth/register.
Executive ViewAI
Organizations using trojan v.2.0.0 face critical risk from CVE-2024-55215, a incorrect default permissions vulnerability rated CVSS 9.8. Attackers could escalate their privileges to gain elevated access beyond their authorized level. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
