Getting an exception to a Sonar raised vulnerability which remains after applying a possible fix (javasecurity:S5167)

As Sonar recommends the requests which contain invalid headers should be thrown away as IO Exceptions after validating against a whitelist.

However, even after validating the retrieved correlation Id, vulnerability still remains.

Hello Gayan,

version 8.6 of SonarQube is not supported anymore. Do you have the possibility to upgrade to SonarQube 9.0? It contains many improvements and might already solve your problem.

That said, we are aware of some problems with rule S5167 and plan to improve it soon.

Are there any changes that are being made to that rule after the 8.6 release? In that case we could consider upgrading.

Rule S5167 is part of the SonarSecurity analyzer and the complete analyzer was drastically improved since version 8.6.

Ok, got it. Thanks for the information.
