LF Edge eKuiper is a lightweight internet of things (IoT) data analytics and stream processing engine. Prior to version 2.1.0 user with rights to modificate the service (e.g. kuiperUser role) can inject a cross-site scripting payload into Connection Configuration key `Name` (`confKey`) parameter. After this setup, when any user with access to this service (e.g. admin) tries to delete this key, a payload acts in the victim's browser. Version 2.1.0 fixes the issue.

Read the publisher's advisory### Summary Stored Cross-Site Scripting (XSS) vulnerability allows attackers to inject malicious scripts into web applications, which can then be executed in the context of other users' browsers. This can lead to unauthorized access to sensitive information, session hijacking, and spreading of malware, impacting user data privacy and application integrity. ### Details A user with rights to modificate the service (e.g. kuiperUser role) can inject XSS Payload into Connection Configuration key `Name` (`confKey`) parameter. Then, after any user with access to this service (e.g. admin) will try to delete this key, a payload will act in victim's browser. ### PoC 1. Authorize as a user with rights to modificate the service (e.g. kuiperUser role). 2. Create a service or go to the existing one and access the *Configuration > Connection* page:  3. Open any existing Connection and press on `Add configuration key`:  4. Set any name and Address, then intercept the request and add the following payload to the `confKey` parameter: `123%3Cimg%20src=1%20onerror%3dalert%281%29%3E`:  5. A new configuration key then will be set:  6. *(Optional)* You can authorize another user with access to this service. For nexe steps I will use admin user 7. After we push on delete button (trash icon) opposite the created connection, the payload will work:  ### Impact Stored Cross-site Scripting (XSS) vulnerability Reported by Alexey Kosmachev, Lead Pentester from Bi.Zone

Read the publisher's advisoryCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
