Attack Vector: Adjacent
Attack Complexity: Low
Privileges Required: Low
User Interaction: Required
Scope: Unchanged
Confidentiality: None
Integrity: None
Availability: High

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

To mitigate CVE-2024-37664, organizations should first verify if they are using the Redmi router RB03 with firmware version 1.0.57 and monitor for official firmware updates or patches from the vendor. Until a patch is available, network administrators should segment WLANs to restrict access between users, minimizing the risk of an attacker sharing the same wireless network as victims. Implementing strong WLAN access controls, such as WPA3 encryption and client isolation features, can reduce the likelihood of local attackers. Network monitoring tools should be configured to detect unusual TCP RST packet patterns indicative of exploitation attempts. Additionally, consider deploying intrusion detection/prevention systems (IDS/IPS) capable of identifying forged TCP resets. Educate users about the risks of connecting to unsecured or shared WLANs. For critical environments, replacing vulnerable routers with devices from vendors with timely security updates may be necessary. Finally, maintain an inventory of network devices and regularly review their firmware versions and security advisories.

Description

Redmi router RB03 v1.0.57 is vulnerable to TCP DoS or hijacking attacks. An attacker in the same WLAN as the victim can disconnect or hijack the traffic between the victim and any remote server by sending out forged TCP RST messages to evict NAT mappings in the router.

Impact

The primary impact of this vulnerability is on the availability of network services for users connected through the affected Redmi router RB03. By evicting NAT mappings via forged TCP RST packets, attackers can cause denial of service by disconnecting active TCP sessions, disrupting business operations, communications, and critical services relying on stable network connections. Additionally, the potential for traffic hijacking could allow attackers to intercept or manipulate data flows, leading to further security risks such as session hijacking or man-in-the-middle attacks. Organizations relying on this router model in environments with shared WLAN access are particularly vulnerable. The disruption could affect remote work, cloud service access, and internal communications. Although the vulnerability does not directly impact confidentiality or integrity, the availability impact can cause operational downtime and loss of productivity. The requirement for local network access limits the attack scope but does not eliminate risk in environments with many users or guest networks.
