CVE-2007-1693
HighSummary
Moduł kanału SIP w Yet Another Telephony Engine (Yate) przed wersją 1.2.0 ustawia parametr caller_info_uri przy użyciu niepoprawnej zmiennej, która może być NULL. To umożliwia zdalnym atakującym spowodowanie awarii aplikacji poprzez nagłówek Call-Info bez parametru purpose.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do wywołania awarii aplikacji, co prowadzi do przerwy w dostępności usług telekomunikacyjnych. Może to wpłynąć na ciągłość działania organizacji i zaufanie użytkowników.
Recommendation
Zaleca się aktualizację Yate do wersji 1.2.0 lub nowszej, aby usunąć tę podatność. Dodatkowo, monitorowanie i ograniczenie dostępu do interfejsów SIP może pomóc w minimalizacji ryzyka.

Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD `id_token`s during OAuth login. Deployments are affected only when the FAB auth manager is configured with Azure AD as an OAuth provider. Because the signing keys are fetched from Microsoft's multi-tenant JWKS endpoint, an `id_token` minted in any Azure tenant — including one the attacker creates — passes signature verification, and the username and role assignments are then read from that attacker-controlled token. Anyone able to register an Azure tenant can therefore authenticate to the Airflow UI with no prior access to the deployment.

Original NVD description (English source)
The SIP channel module in Yet Another Telephony Engine (Yate) before 1.2.0 sets the caller_info_uri parameter using an incorrect variable that can be NULL, which allows remote attackers to cause a denial of service (NULL dereference and application crash) via a Call-Info header without a purpose parameter.
