TencentOS Server 3: grafana (TSSA-2024:0549)

high Nessus Plugin ID 239954

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0549 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2024-24791:
The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an Expect:
100-continue header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending Expect: 100-continue requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
