CVE-2026-22919 is a vulnerability affecting Sick's TDC-X401GL firmware, which allows an attacker with administrative access to inject malicious content into the login page. This could enable cross-site scripting (XSS) attacks, allowing the extraction of sensitive data. The vulnerability is classified as low severity, with a CVSS score of 3.8.
The fact that this vulnerability enables XSS attacks indicates that organizations must remain vigilant against potential data breaches. Although the attack complexity is low, the requirement for administrative privileges means that an attacker would need elevated access to exploit this vulnerability.
Organizations should prioritize patching immediately due to the potential for data loss and the sensitivity of the information that could be compromised. Remediation steps should be integrated into the existing security protocols to ensure that such vulnerabilities are not exploited.
As of now, there are no known exploits or public proof of concepts available for this vulnerability, which suggests that it may not yet be widely recognized by threat actors. However, this does not eliminate the risk associated with it.
Given the nature of the vulnerability, organizations should address it within their regular patch management cycles, ensuring that all administrative access points are secured against unauthorized use.
Vulnerability Details
The official description of CVE-2026-22919 states that 'An attacker with administrative access may inject malicious content into the login page, potentially enabling cross-site scripting (XSS) attacks, leading to the extraction of sensitive data.' This vulnerability is linked to CWE-79, indicating its nature as a cross-site scripting issue.
The vulnerability was published on January 15, 2026, and is classified under the following metrics:
Metric | Value |
|---|---|
CVSS Score | 3.8 (Low) |
Attack Vector | Network |
Privileges Required | High |
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input on the login page, which allows an attacker with administrative privileges to inject malicious scripts. The attack vector is network-based, meaning the attacker can exploit this vulnerability remotely without physical access to the device.
The attack complexity is low, as the attacker does not need advanced skills or resources to exploit this vulnerability. However, administrative privileges are required to perform the injection, which limits the potential for widespread exploitation.
The vulnerability impacts confidentiality and integrity, as sensitive data could be compromised through successful XSS attacks. However, there is no impact on availability, making the overall risk relatively moderate in terms of operational disruption.
Risk & Impact Analysis
Risk to organizations includes the potential for data breaches resulting from this vulnerability. Since an attacker can inject malicious scripts, it poses a significant risk to sensitive data stored within the system.
Organizations need to recognize the potential for exploitation, particularly given that administrative access is a requirement for exploiting this vulnerability. Although there are currently no known exploits, the possibility remains for future attacks.
Due to the medium severity rating, organizations should address this vulnerability within their patch cycles but may not need to prioritize it over more critical vulnerabilities.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected product is the Sick TDC-X401GL firmware, specifically all versions prior to 1.5.0. Organizations using this firmware should ensure they are running the latest version to mitigate the associated risks.
Mitigation & Remediation
Organizations should schedule remediation by applying the necessary patches or updates to the Sick TDC-X401GL firmware. If a patch is unavailable, alternative workarounds should be explored to mitigate the risk of exploitation.
Configuration hardening is also recommended to minimize administrative access and reduce the attack surface. Implementing network controls to restrict access to the login page can further enhance security.
Organizations should maintain vigilance through monitoring for unusual activity related to the login page or administrative access attempts.
