CVE-2025-20243
HighSummary
Podatność w serwerach zarządzania i VPN oprogramowania Cisco Secure Firewall ASA oraz Secure FTD może pozwolić nieautoryzowanemu, zdalnemu atakującemu na nieoczekiwane przeładowanie urządzenia, co prowadzi do stanu DoS. Problem wynika z niewłaściwej walidacji danych wejściowych dostarczanych przez użytkownika na interfejsie z usługami VPN.
Risk Assessment
Organizacja może doświadczyć przerwy w dostępności usług, co może prowadzić do zakłóceń w działalności oraz potencjalnych strat finansowych. Atakujący może wykorzystać tę podatność do wywołania stanu DoS na dotkniętym urządzeniu.
Recommendation
Zaleca się aktualizację oprogramowania Cisco Secure Firewall ASA oraz Secure FTD do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto monitorować ruch HTTP do serwerów VPN w celu wykrywania potencjalnych prób ataków.

- CVE-2026-95848Critical
Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when a configured authenticator or authorizator class cannot be loaded, Server.initializeAuthenticator and Server.initializeAuthorizatorPolicy treat the failure as though no custom class was configured and fall back to AcceptAllAuthenticator or PermitAllAuthorizatorPolicy. A misspelled class name, missing dependency, constructor failure, or classpath problem can therefore start the broker with authentication or authorization disabled even though the operator configured those controls. This issue is fixed in version 0.18.1.
- CVE-2026-85724Critical
Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when pattern-based ACL rules are configured, AuthorizationsCollector.canDoOperation substitutes client ID and username values directly into rules containing %c or %u and then treats the result as an MQTT topic filter. A client that uses + or # in either identity can broaden the substituted filter and gain cross-tenant read and write access. A # identity can also produce an invalid filter that triggers a NullPointerException in Topic.match and disrupts session processing. This issue is fixed in version 0.18.1.

If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal.
Original NVD description (English source)
A vulnerability in the management and VPN web servers of Cisco Secure Firewall ASA Software and Secure FTD Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a DoS condition. This vulnerability is due to improper validation of user-supplied input on an interface with VPN web services. An attacker could exploit this vulnerability by sending crafted HTTP requests to a targeted web server on an affected device. A successful exploit could allow the attacker to cause a DoS condition when the device reloads.
