    Title
    HTTP Request/Response Smuggling in Altitude Communication Server
    Summary
    Illegal HTTP request traffic vulnerability (CL.0) in Altitude Communication Server, caused by inconsistent analysis of multiple HTTP requests over a single Keep-Alive connection using Content-Length headers. This can cause a desynchronization of requests between frontend and backend servers, which could allow request hiding, cache poisoning or security bypass.

    CVE-2025-41082 (GCVE-0-2025-41082)

    Vulnerability from nvd – Published: 2026-01-26 09:24 – Updated: 2026-01-26 13:55
    VLAI
    Title
    HTTP Request/Response Smuggling in Altitude Communication Server
    Summary
    Illegal HTTP request traffic vulnerability (CL.0) in Altitude Communication Server, caused by inconsistent analysis of multiple HTTP requests over a single Keep-Alive connection using Content-Length headers. This can cause a desynchronization of requests between frontend and backend servers, which could allow request hiding, cache poisoning or security bypass.
    Severity
    6.9 (Medium)
