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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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).

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Mar 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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.

AI-suggested

Given the absence of an official patch, organizations should implement several specific mitigations: 1) Restrict network access to the management interfaces of LBT T300-T390 devices by using firewalls or access control lists to limit exposure to trusted IP addresses only. 2) Monitor network traffic for unusual POST requests targeting the updateCurAPlist function or containing suspicious ApCliSsid parameters to detect potential exploitation attempts. 3) If possible, disable or restrict the functionality that processes the ApCliSsid parameter until a patch is available. 4) Regularly check for firmware updates or security advisories from the vendor and apply patches promptly once released. 5) Employ network segmentation to isolate vulnerable devices from critical infrastructure to minimize impact in case of exploitation. 6) Maintain up-to-date backups and incident response plans to quickly recover from potential DoS incidents. 7) Consider deploying intrusion prevention systems (IPS) with custom signatures to detect and block exploit attempts targeting this vulnerability.

Description

LBT T300-T390 v2.2.1.8 were discovered to contain a stack overflow via the ApCliSsid parameter in the updateCurAPlist function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

Impact

The primary impact of CVE-2024-27572 is a Denial of Service condition on affected LBT T300-T390 devices. These devices are typically used in networking environments, potentially as wireless access points or similar infrastructure components. A successful exploit can cause device crashes or reboots, disrupting network connectivity and availability. For organizations relying on these devices for critical network access, this can lead to operational downtime, loss of productivity, and potential cascading effects on dependent systems. Since the vulnerability can be exploited remotely without authentication, attackers can target these devices from anywhere on the internet or internal networks, increasing the risk of widespread disruption. Although no data confidentiality or integrity compromise is indicated, the loss of availability can have severe consequences, especially in environments requiring high uptime such as enterprises, service providers, or public institutions.
