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: 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: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

CVE published 23 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed

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 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 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

Network-level mitigations include enforcing strict TLS interception policies, deploying network segmentation to isolate monitoring software installation traffic, and using VPNs or trusted networks for software deployment. Monitoring network traffic for unusual curl.exe usage or unexpected downloads during installation can help detect exploitation attempts. Endpoint detection and response (EDR) solutions should be configured to alert on execution of unexpected binaries with SYSTEM privileges. Organizations should consider alternative employee monitoring solutions with verified secure installation processes. Additionally, educating IT staff about the risks of using insecure installation methods and enforcing strict software supply chain security policies will reduce exposure. Finally, maintaining comprehensive backups and incident response plans will mitigate damage in case of compromise.

Description

The CleverControl employee monitoring software (v11.5.1041.6) fails to validate TLS server certificates during the installation process. The installer downloads and executes external components using curl.exe --insecure, enabling a man-in-the-middle attacker to deliver malicious files that are executed with SYSTEM privileges. This can lead to full remote code execution with administrative rights. No patch is available as the vendor has been unresponsive. It is assumed that previous versions are also affected, but this is not confirmed.

Impact

For European organizations, this vulnerability poses a significant risk due to the potential for full system compromise via remote code execution with SYSTEM privileges. Employee monitoring software is often deployed in corporate environments, including sensitive sectors such as finance, healthcare, and government, making the impact on confidentiality and operational continuity critical. Attackers exploiting this flaw could gain persistent access, steal sensitive data, or disrupt operations. The lack of vendor response and patch availability increases the risk exposure duration. Additionally, the vulnerability could be leveraged in targeted attacks or broader campaigns exploiting network-level interception, especially in environments with insufficient network segmentation or weak perimeter defenses. Organizations in Europe with remote or hybrid workforces may be particularly vulnerable if installation occurs over untrusted networks. The impact extends beyond individual endpoints to potentially compromise entire corporate networks if lateral movement is achieved post-exploitation.
