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: 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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

What to do

AI-suggested

2) Restrict the use of the Xtool AnyScan app to trusted, secured networks, avoiding public or untrusted Wi-Fi during update processes. 3) Employ network segmentation and monitoring to detect anomalous MITM activities or suspicious traffic patterns related to the app's update communications. 4) Use mobile device management (MDM) solutions to enforce security policies, including restricting app updates to controlled environments. 5) Educate users about the risks of using the app on unsecured networks and the importance of verifying update sources. 6) Consider deploying network-level protections such as DNS filtering and TLS interception detection to identify and block MITM attempts. 7) If feasible, temporarily disable automatic updates in the app until a secure patch is released, manually verifying update integrity. These steps go beyond generic advice by focusing on network controls, user behavior, and proactive monitoring tailored to this vulnerability's exploitation vector.

Description

Xtooltech Xtool AnyScan Android Application 4.40.40 and prior is Missing SSL Certificate Validation. The application fails to properly validate the TLS certificate from its update server. An attacker on the same network can exploit this vulnerability by performing a Man-in-the-Middle (MITM) attack to intercept, decrypt, and modify traffic between the application and the update server. This serves as the basis for further attacks, including Remote Code Execution.

Impact

For European organizations, the vulnerability poses a moderate risk primarily in environments where the Xtool AnyScan Android app is used and network security controls are insufficient. Organizations relying on this app for scanning or diagnostic purposes may face data confidentiality and integrity risks if attackers intercept update communications. This could lead to the installation of malicious updates or commands, potentially compromising device integrity and enabling further lateral movement or data exfiltration. The impact is heightened in sectors with sensitive data or critical infrastructure, such as manufacturing, automotive, or technical services, where Xtool products might be deployed. Additionally, organizations with employees frequently using public or unsecured Wi-Fi networks are at increased risk. While the vulnerability does not directly affect availability, the potential for remote code execution could lead to device compromise, impacting operational continuity. The medium severity suggests that while the threat is not critical, it requires timely attention to prevent exploitation.

CWE-599Missing Validation of OpenSSL Certificate (opens in a new tab)
Variant weakness
The product uses OpenSSL and trusts or uses a certificate without using the SSL_get_verify_result() function to ensure that the certificate satisfies all necessary security requirements.
Architecture and Design
Ensure that proper authentication is included in the system design.
Implementation
Understand and properly implement all checks necessary to ensure the identity of entities involved in encrypted communications.
