TencentOS Server 3: curl (TSSA-2022:0142)

high Nessus Plugin ID 239946

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 multiple vulnerabilities as referenced in the TSSA-2022:0142 advisory.

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

CVE-2022-22576:
An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This issue leads to an authentication bypass, either by mistake or by a malicious actor.

CVE-2022-27774:
An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow leaking credentials to other servers when it follows redirects from auth- protected HTTP(S) URLs to other protocols and port numbers.

CVE-2022-27776:
A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number. Sending the same set of headers to a server on a different port number is a problem for applications that pass on custom Authorization: or Cookie:headers. Those headers often contain privacy-sensitive information or data.

CVE-2022-27782:
A vulnerability was found in curl. This issue occurs because curl can reuse a previously created connection even when a TLS or SSH-related option is changed that should have prohibited reuse. This flaw leads to an authentication bypass, either by mistake or by a malicious actor.

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

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

Solution

Update the affected packages.
