The version of Oracle Essbase installed on the remote host is missing a security patch from the August 2026 Critical Security Patch Update (CSPU). It is, therefore, affected by multiple vulnerabilities:

  - Vulnerability in Oracle Essbase (component: Essbase Web Platform (Apache HTTP Server)). The supported version     that is affected is 21.8.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network     access via HTTP to compromise Oracle Essbase. Successful attacks of this vulnerability can result in takeover     of Oracle Essbase. (CVE-2026-29167)

  - Vulnerability in Oracle Essbase (component: Infrastructure). The supported version that is affected is     21.8.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to     compromise Oracle Essbase. Successful attacks of this vulnerability can result in takeover of Oracle Essbase.
    (CVE-2026-70689)

  - Vulnerability in Oracle Essbase (component: Calculator). The supported version that is affected is 21.8.1.0.0.
    Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise     Oracle Essbase. Successful attacks of this vulnerability can result in takeover of Oracle Essbase.
    (CVE-2026-70688)

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

    * openssl: Trust-Anchor Substitution via cert/issuer Typo in CMP rootCaKeyUpdate (CVE-2026-42769)

    * openssl: FFC-DH Peer Validation Uses Attacker-Supplied q (CVE-2026-42770)

    * openssl: AES-OCB IV Ignored on EVP_Cipher() Path (CVE-2026-45445)

    * openssl: Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes (CVE-2026-45446)

    * openssl: Heap Use-After-Free in OpenSSL PKCS7_verify() (CVE-2026-45447)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0503 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-45447:
    Issue summary: A specially crafted PKCS#7 or S/MIME signed message could     trigger a use-after-free during PKCS#7 signature verification.

    Impact summary: A use-after-free may result in process crashes, heap     corruption, or potentially remote code execution.

    When processing a PKCS#7 or S/MIME signed message, if the SignedData     digestAlgorithms field is present as an empty ASN.1 SET, OpenSSL may     incorrectly free a caller-owned BIO during PKCS7_verify(). A subsequent     use of the BIO by the calling application results in a use-after-free     condition.

    In the common case this occurs when the application later calls     BIO_free() on the BIO originally passed to PKCS7_verify(). Depending     on allocator behavior and application-specific BIO usage patterns, this     may result in a crash or other memory corruption. In some application     contexts this may potentially be exploitable for remote code execution.

    Applications that process PKCS#7 or S/MIME signed messages using OpenSSL     PKCS#7 APIs may be affected. Applications using the CMS APIs for this     processing are not affected.

    The FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this     issue, as the affected code is outside the OpenSSL FIPS module boundary.

    CVE-2026-34182:
    Issue Summary: Cryptographic Message Services (CMS) processing fails to perform     sufficient input validation on the cipher and tag length fields of     AuthEnvelopedData containers, leading to various potential compromises.

    Impact Summary: Attackers making use of these vulnerabilities may achieve     key-equivalent functionality for a given CMS recipient and/or bypass integrity     validation for a given message.

    In one use case, an attacker may send a CMS message containing     AuthEnvelopedData with the cipher specified as a non-AEAD cipher.  OpenSSL     erroneously allows this selection, and attempts to decrypt and validate the     message.

    An on-path attacker who captures one legitimate AES-GCM AuthEnvelopedData     addressed to the victim can re-emit it with the recipientInfos set left     byte-for-byte intact, so the victim's private key still unwraps the genuine CEK     (the content-encryption key), but with the inner OID rewritten to AES-256-OFB     (Output Feedback Mode, an unauthenticated keystream mode) and with an     attacker-chosen IV and ciphertext. The victim initializes AES-256-OFB under the     real CEK, never consults the MAC field, and CMS_decrypt() returns success.

    If the application under attack responds to the attacker with any indicator     showing success or failure of the decryption effort, it is possible for the     attacker to use this as an oracle to obtain key equivalent functionality for the     CEK used for the chosen recipient of the message.

    In another use case, an attacker can reduce the tag length of the chosen AEAD     cipher for a given AuthEnvelopedData container to be a single byte long,     allowing an attacker to brute force CMS decryption, producing an integrity     bypass for applications that trust CMS_decrypt() to reject modified content.

    The FIPS modules are not affected by this issue.
