TencentOS Server 2: ipa (TSSA-2024:0163)

high Nessus Plugin ID 239277

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0163 advisory.

 Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

 CVE-2024-3183:
 A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the clients session key. This key is different for each new session, which protects it from brute force attacks.
 However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the users password.

 If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principals password).

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.
