A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS) attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue can result in a large amount of computational consumption, causing a denial of service attack.

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-2024:0814 advisory.

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

    CVE-2023-6681:
    A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS)     attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue     can result in a large amount of computational consumption, causing a denial of service attack.

    CVE-2024-28102:
    JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an     attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression     ratio. When the server processes this token, it will consume a lot of memory and processing time. Version     1.5.6 fixes this vulnerability by limiting the maximum token length.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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