🛡️ CVE-2024-43393 — fl-mguard-2102-firmware

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H

• Attack vector: Network — reachable from anywhere that can route to the service.
• Attack complexity: Low — the attack works reliably, with no preparation.
• Privileges required: Low — an ordinary user account is enough.
• User interaction: None — nobody has to be tricked into anything.
• Scope: Unchanged — the damage stays inside the vulnerable component.
• Confidentiality impact: None.
• Integrity impact: High — total loss, or loss the attacker controls.
• Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2024-43393 is classified as CWE-94: Code Injection. Input is incorporated into code that the runtime evaluates, so an attacker can have their own code executed.
