CVE-2025-26411 is a high-severity vulnerability that affects the Wattsense Bridge devices. An authenticated attacker can utilize the Plugin Manager of the web interface to upload malicious Python files, which enables them to gain remote root access to the device. This vulnerability requires the attacker to have a valid user account on the Wattsense web interface to exploit the issue.
With a CVSS score of 8.8, this vulnerability is classified as high severity. The potential impact includes high confidentiality, integrity, and availability risks to the affected devices. Organizations relying on Wattsense Bridge devices must prioritize addressing this vulnerability by applying the necessary firmware updates.
The urgency for organizations to patch this vulnerability is critical, especially considering that it allows for remote root access. Organizations should ensure their devices are running firmware version BSP >= 6.1.0, where this issue has been resolved. Failure to apply these updates may expose organizations to significant security risks.
As of now, there are no known public exploits for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and monitor any developments regarding this vulnerability.
Vulnerability Details
The official description of CVE-2025-26411 states that an authenticated attacker is able to use the Plugin Manager of the web interface of the Wattsense Bridge devices to upload malicious Python files to the device. This vulnerability allows the attacker to gain remote root access to the device. The issue has been fixed in recent firmware versions BSP >= 6.1.0.
The vulnerability is classified under CWE-434, which pertains to improper handling of file uploads. This could lead to significant security impacts if not mitigated. The CVSS score of 8.8 indicates a high risk that should not be ignored.
Technical Analysis
Root cause of this vulnerability lies in the improper handling of file uploads, allowing attackers to upload Python scripts that can be executed on the device. The attack vector is network-based, requiring low attack complexity and low privileges. No user interaction is necessary, which increases the risk of exploitation.
The potential impacts of this vulnerability are severe, as attackers may leverage the access to compromise the confidentiality, integrity, and availability of the device. The requirement for only low privileges to exploit this vulnerability makes it particularly dangerous.
Risk & Impact Analysis
Risk to organizations includes exposure to unauthorized remote access, which can lead to data breaches and operational disruptions. The blast radius for this vulnerability could affect all devices running vulnerable firmware versions, emphasizing the need for immediate action.
Given its high CVSS score and the potential for exploitation, organizations should treat the remediation of this vulnerability as a priority. The urgency to patch is critical, as attackers may exploit similar vulnerabilities in the wild.
