Summary
Protection mechanism failure in LLM Scaler software within Ring 3: User Applications may allow an escalation of privilege. The attack requires a privileged user, low complexity, local access, and passive user interaction. The vulnerability impacts confidentiality, integrity, and availability (high).
Risk Assessment
Escalation of privilege may allow an attacker to gain full control of the system, potentially leading to breaches of confidentiality, integrity, and availability. System privileges are required, but the risk is high.
Recommendation
It is recommended to update LLM Scaler software to the latest version with fixes. Also, restrict access to the tool and monitor activity of privileged users.
Original NVD description (English source)
Protection mechanism failure for some LLM Scaler software within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
