A security issue was discovered in the LRA Coordinator component of Narayana. When Cancel is called in LRA, an execution time of approximately 2 seconds occurs. If Join is called with the same LRA ID within that timeframe, the application may crash or hang indefinitely, leading to a denial of service.
Details

|---|---|---|
| MEDIUM | 5.9 | CVE-2024-8447 |
Exploitation
To exploit this vulnerability, an attacker can initiate a Cancel operation in the LRA Coordinator component and then attempt to call Join with the same LRA ID within the 2-second execution window. This can lead to application crashes or indefinite hangs, resulting in a denial of service.
Affected Products
