    CVE-2021-4467 (GCVE-0-2021-4467)

    Vulnerability from nvd – Published: 2025-11-14 22:51 – Updated: 2025-11-18 16:33
    VLAI
    Title
    Positive Technologies MaxPatrol 8 & XSpider Remote DoS
    Summary
    Positive Technologies MaxPatrol 8 and XSpider contain a remote denial-of-service vulnerability in the client communication service on TCP port 2002. The service generates a new session identifier for each incoming connection without adequately limiting concurrent requests. An unauthenticated remote attacker can repeatedly issue HTTPS requests to the service, causing excessive allocation of session identifiers. Under load, session identifier collisions may occur, forcing active client sessions to disconnect and resulting in service disruption.
