CVE-2025-63363

CVE-2025-63363 affects Waveshare RS232/485 TO WIFI ETH (B) Serial to Ethernet/Wi‑Fi Gateway. The root cause is a lack of Management Frame Protection in firmware version 3.1.1.0 (HW 4.3.2.1; Webpage 7.04T.07.002880.0301), enabling de‑authentication attacks via crafted frames broadcast without auth...

CVE-2025-55039 Apache Spark, Apache Spark: RPC encryption defaults to unauthenticated AES-CTR mode, enabling man-in-the-middle ciphertext modification attacks

This issue affects Apache Spark versions before 3.4.4, 3.5.2 and 4.0.0. Apache Spark versions before 4.0.0, 3.5.2 and 3.4.4 use an insecure default network encryption cipher for RPC communication between nodes. When spark.network.crypto.enabled is set to true it is set to false by default, but...

CVE-2025-55039

CVE-2025-55039 affects Apache Spark prior to 3.4.4, 3.5.2 and 4.0.0. When spark.network.crypto.enabled is true (default false) and spark.network.crypto.cipher is not configured, Spark uses AES/CTR/NoPadding for RPC traffic, enabling encryption without authentication. A MITM could flip bits in cip...

SimpleSAMLphp Unauthenticated encryption in CBC mode

SimpleSAMLphp 1.14.12 and earlier make it easier for man-in-the-middle attackers to obtain sensitive information by leveraging use of the aesEncrypt and aesDecrypt methods in the SimpleSAML/Utils/Crypto class to protect session identifiers in replies to non-HTTPS service providers...
