CVE-2007-2782
HighSummary
Packeteer PacketShaper wykorzystuje stałe przyrosty w wartościach początkowego numeru sekwencyjnego TCP (ISN), co umożliwia zdalnym atakującym przewidywanie wartości ISN i przeprowadzanie ataków typu hijacking sesji lub zakłócanie jej działania.
Risk Assessment
Atakujący mogą przejąć kontrolę nad sesjami użytkowników lub zakłócić ich komunikację, co może prowadzić do utraty danych lub naruszenia prywatności.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszej wersji, która eliminuje tę podatność oraz wdrożenie dodatkowych mechanizmów zabezpieczających sesje TCP.

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)
Packeteer PacketShaper uses fixed increments in TCP initial sequence number (ISN) values, which allows remote attackers to predict the ISN value, and perform session hijacking or disruption.
