CVE-2025-23198 is a medium-severity vulnerability affecting Librenms, a community-based GPL-licensed network monitoring system. This vulnerability allows remote attackers to exploit a stored cross-site scripting (XSS) issue via the parameters in the URL. Specifically, the vulnerable endpoint is `/device/$DEVICE_ID/edit`, where the parameter `display` can be manipulated. Affected versions include all versions up to 24.10.1.
When a user interacts with the page showing the data, the injected malicious script executes immediately, leading to potential unauthorized actions or data exposure. This issue poses a significant risk to organizations using this software, particularly in instances where sensitive information is displayed.
This vulnerability has been addressed in release version 24.11.0, and users are advised to upgrade as soon as possible. There are no known workarounds available for this vulnerability, making upgrading the only viable option to mitigate the risk.
As organizations assess their security posture, it is crucial to prioritize this update to prevent exploitation attempts that may compromise the integrity and confidentiality of their systems.
Vulnerability Details
The CVSS score for this vulnerability is 4.6, categorized as medium severity. The attack vector is primarily over the network, with a low attack complexity. Attackers require low privileges and user interaction is necessary for exploitation. The impacts on confidentiality and integrity are both classified as low, while there is no impact on availability.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input in the display parameter. When the server processes this input without adequate validation or sanitization, it allows for the injection of malicious scripts.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is low, as it does not require special conditions or extensive knowledge of the system. Once the malicious script is injected, user interaction is required for it to execute, as the user must view or interact with the affected page.
Given the nature of the XSS vulnerability, it can lead to unauthorized actions on behalf of the user, such as session hijacking or data theft. Organizations should be aware of the potential impacts and take immediate action to mitigate the risks.
Risk & Impact Analysis
Risk to organizations includes exposure to malicious script execution, which can lead to unauthorized access to sensitive data or actions being performed without user consent. The potential blast radius is significant, especially for organizations that utilize Librenms for critical network monitoring tasks.
Given the low complexity of the attack and the requirement for user interaction, organizations must educate users about the risks and ensure that they are not interacting with suspicious links or content. The urgency for remediation is medium, as organizations have a window to address this before it is widely exploited.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Librenms prior to 24.11.0 are affected by this vulnerability. Organizations should verify their current version and upgrade to 24.11.0 or later to mitigate the risks associated with this flaw.
Mitigation & Remediation
Organizations should prioritize patching by upgrading to Librenms version 24.11.0 or later. This update addresses the stored XSS vulnerability effectively. If immediate upgrade is not possible, organizations should review their web application security practices and consider implementing strong input validation and sanitization measures.
For further assistance in validating the effectiveness of the patch, organizations may consider utilizing penetration testing to identify any remaining vulnerabilities.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual script execution or unexpected behavior on the `/device/$DEVICE_ID/edit` page. Behavioral anomalies could indicate an attempted exploitation or successful compromise.
