CVE-2025-20263
HighSummary
Podatność w interfejsie usług sieciowych oprogramowania Cisco Secure Firewall Adaptive Security Appliance (ASA) oraz Cisco Secure Firewall Threat Defense (FTD) może umożliwić nieautoryzowanemu, zdalnemu atakującemu spowodowanie przepełnienia bufora na podatnym systemie. Problem ten wynika z niewystarczających kontroli granic dla określonych danych przekazywanych do interfejsu usług sieciowych.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do przepełnienia bufora, co skutkuje ponownym uruchomieniem systemu i może prowadzić do stanu odmowy usługi (DoS). Taka sytuacja może znacząco wpłynąć na dostępność usług w organizacji.
Recommendation
Zaleca się aktualizację oprogramowania Cisco do najnowszej wersji, która zawiera poprawki zabezpieczeń eliminujące tę podatność. Dodatkowo, warto wprowadzić monitorowanie ruchu HTTP w celu wykrywania potencjalnych prób ataków.

orval versions 8.14.0 through 8.28.1 contain a code injection vulnerability in the @orval/effect generator that converts OpenAPI schema defaults into template literals. Attackers can inject arbitrary JavaScript expressions via schema defaults containing ${...} syntax, which are executed at module scope when the generated code is built or imported.
- CVE-2026-96754Critical
orval versions before 8.29.0 contain a code injection vulnerability in the @orval/hono generator that fails to escape OpenAPI path values in single-quoted route literals. Attackers can craft an OpenAPI document with an apostrophe in a static path segment to inject arbitrary JavaScript code that executes when the generated TypeScript module is imported.
- 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 web services interface of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected system. This vulnerability is due to insufficient boundary checks for specific data that is provided to the web services interface of an affected system. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could cause the system to reload, resulting in a denial of service (DoS) condition.
