    CVE-2026-6644 (GCVE-0-2026-6644)

    Vulnerability from cvelistv5 – Published: 2026-04-20 06:54 – Updated: 2026-04-30 12:48
    VLAI
    Title
    A command injection vulnerability was found in the PPTP VPN Clients on the ADM
    Summary
    A command injection vulnerability was found in the PPTP VPN Clients on the ADM. The vulnerability allows an administrative user to break out of the restricted web environment and execute arbitrary code on the underlying operating system. This occurs due to insufficient validation of user-supplied input before it is passed to a system shell. Successful exploitation allows an attacker to achieve Remote Code Execution (RCE) and fully compromise the system. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RR42 as well as from ADM 5.0.0 through ADM 5.1.2.REO1.

    CVE-2026-6643 (GCVE-0-2026-6643)

    Vulnerability from cvelistv5 – Published: 2026-04-20 06:34 – Updated: 2026-04-20 13:46

    Title
    A stack-based buffer overflow vulnerability in the VPN Clients on the ADM
    Summary
    A stack-based buffer overflow vulnerability was found in the VPN Clients on the ADM. The issue stems from the use of unbounded sscanf() and passing user-controlled data directly to printf(). Due to the lack of PIE and Stack Canary protections, an authenticated remote attacker can exploit these to execute arbitrary code as the web server user. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RR42 as well as from ADM 5.0.0 through ADM 5.1.2.REO1.
