High
| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Go versions prior to 1.18.6
Go versions 1.19.x prior to 1.19.1
Description
The issue is related to the net/http package in Go, where an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error, leading to a denial of service. This can be exploited by a malicious client. The vulnerability is also associated with a lack of input data sanitization, which can impact the confidentiality, integrity, and availability of protected information.
Recommendations
For Go versions prior to 1.18.6, update to version 1.18.6 or later to resolve the issue.
For Go versions 1.19.x prior to 1.19.1, update to version 1.19.1 or later to resolve the issue.
As a temporary workaround, consider restricting access to the net/http package to minimize the risk of exploitation.
