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-2024:0914 advisory.

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

    CVE-2023-50782:
    A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt     captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or     sensitive data.

    CVE-2024-2408:
    The openssl_private_decrypt function in PHP, when using PKCS1 padding (OPENSSL_PKCS1_PADDING, which is the     default), is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes the     changes from this pull request: https://github.com/openssl/openssl/pull/13817     (rsa_pkcs1_implicit_rejection).

PHP Windows builds for the versions 8.1.29, 8.2.20 and 8.3.8 and above include     OpenSSL patches that fix the vulnerability.

    CVE-2024-3296:
    A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover     a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an     attacker would have to be able to send a large number of trial messages for decryption. The vulnerability     affects the legacy PKCS#1v1.5 RSA encryption padding mode.

    The vulnerability allows a remote attacker to bypass implemented security restrictions.

    The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a     standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by     PHP applications.

    Note, the vulnerability exists due to incomplete fix for #VU67756 (CVE-2022-31629). (CVE-2024-2756)

    The vulnerability allows a remote attacker to bypass authentication process.

    The vulnerability exists due to an error in within the password_verify() function, which can erroneously     return true. A remote attacker can bypass implemented authentication based on the vulnerable function and     gain unauthorized access to the web application. (CVE-2024-3096)
