Scope: Changed
Confidentiality: High
Integrity: High
Availability: High

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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 26 Oct 2026.

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 or the CVSS exploit maturity 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

To mitigate CVE-2024-48548 effectively, organizations should implement the following specific measures: 1) Restrict API access by enforcing strong authentication and authorization mechanisms on the device binding API endpoint to prevent unauthorized requests. 2) Implement rate limiting and anomaly detection on API calls to hinder brute force attempts on serial numbers. 3) Monitor logs and network traffic for unusual binding requests or patterns indicative of brute force activity. 4) If possible, disable or restrict the vulnerable API endpoint until a vendor patch is available. 5) Engage with the Cloud Smart Lock vendor to obtain updates or patches addressing this vulnerability. 6) Conduct a thorough inventory of all Cloud Smart Lock devices and review binding configurations to identify unauthorized bindings. 7) Educate security teams about this vulnerability to enhance incident response readiness. 8) Consider network segmentation to isolate IoT devices and minimize exposure to potential attackers. These steps go beyond generic advice by focusing on access control, detection, and vendor engagement specific to the vulnerability's nature.

Description

The APK file in Cloud Smart Lock v2.0.1 has a leaked a URL that can call an API for binding physical devices. This vulnerability allows attackers to arbitrarily construct a request to use the app to bind to unknown devices by finding a valid serial number via a bruteforce attack.

Impact

The impact of CVE-2024-48548 is substantial for organizations relying on Cloud Smart Lock devices for physical security or access control. Unauthorized binding of devices can lead to several severe consequences: attackers may gain control over physical locks, compromising physical security and enabling unauthorized access to facilities or assets. This undermines confidentiality by exposing device associations and potentially sensitive access logs. Integrity is affected as attackers can manipulate device bindings, potentially disrupting normal operations or causing unauthorized device behavior. Availability may also be impacted if attackers bind devices en masse, causing denial of service or operational disruptions. The vulnerability's ease of exploitation without authentication or user interaction increases the risk of widespread abuse. Organizations in sectors such as corporate offices, government facilities, healthcare, and critical infrastructure using Cloud Smart Lock technology face heightened risks. The lack of current patches means the window of exposure remains open, necessitating immediate mitigation efforts to prevent exploitation. Additionally, the ability to brute force serial numbers may allow attackers to scale attacks, increasing the threat scope globally.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
