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-2026:0844 advisory.

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

    CVE-2026-72694:
    A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops     privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following     vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can     trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This     can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive     files.
