The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0499 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-48866:
    ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and     Nginx. Versions prior to 2.9.10 contain a denial of service vulnerability similar to     GHSA-859r-vvv8-rm8r/CVE-2025-47947. The `sanitiseArg` (and `sanitizeArg` - this is the same action but an     alias) is vulnerable to adding an excessive number of arguments, thereby leading to denial of service.
    Version 2.9.10 fixes the issue. As a workaround, avoid using rules that contain the  `sanitiseArg` (or     `sanitizeArg`) action.
