Bouncy Castle for Java before 1.73 contains a potential Denial of Service (DoS) issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 encoded keys, and PKCS7 objects. Parsing a file that has crafted ASN.1 data through the PEMParser causes an OutOfMemoryError, which can enable a denial of service attack. (For users of the FIPS Java API: BC-FJA 1.0.2.3 and earlier are affected; BC-FJA 1.0.2.4 is fixed.)

The version of Oracle Business Intelligence Enterprise Edition (OAS) 7.0.0.0 installed on the remote host is affected by multiple vulnerabilities as referenced in the January 2025 CPU advisory, including the following:

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Analytics Server (SciPy)). Supported versions that are affected are 7.0.0.0.0 and 7.6.0.0.0.     Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to     compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this vulnerability can     result in takeover of Oracle Business Intelligence Enterprise Edition. (CVE-2023-29824)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Platform Security (OpenSSL)). Supported versions that are affected are 7.0.0.0.0, 7.6.0.0.0     and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via     TLS to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this     vulnerability can result in unauthorized access to critical data or complete access to all Oracle Business     Intelligence Enterprise Edition accessible data and unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of Oracle Business Intelligence Enterprise Edition. (CVE-2024-5535)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Analytics Server, Pipeline Test Failures, Installation (Spring Framework)). Supported versions     that are affected are 7.0.0.0.0, 7.6.0.0.0 and 12.2.1.4.0. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Oracle Business Intelligence     Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause     a partial denial of service (partial DOS) of Oracle Business Intelligence Enterprise Edition.     (CVE-2024-38809)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The 12.2.1.4.0 and 14.1.1.0.0 versions of WebLogic Server installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2024 CPU advisory:

  - Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Samples (handlebars)).     Supported versions that are affected are 12.2.1.4.0 and 14.1.1.0.0. Easily exploitable vulnerability allows \     unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of     this vulnerability can result in takeover of Oracle WebLogic Server. (CVE-2021-23369)

  - Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Centralized Thirdparty     Jars (Bouncy Castle Java Library)). Supported versions that are affected are 12.2.1.4.0 and 14.1.1.0.0. Easily     exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise     Oracle WebLogic Server. Successful attacks of this vulnerability can result in unauthorized read access to a subset     of Oracle WebLogic Server accessible data. (CVE-2023-2976)

  - Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Web Container). The     supported version that is affected is 14.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker     with network access via HTTP/2 to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can     result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle WebLogic     Server. (CVE-2023-44487)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-479 advisory.
